NAME
    sys
FILE
    (built-in)
MODULE DOCS
    http://docs.python.org/library/sys
DESCRIPTION
    This module provides access to some objects used or maintained by the
    interpreter and to functions that interact strongly with the interpreter.
   
    Dynamic objects:
   
    argv -- command line arguments; argv[0] is the script pathname if known
    path -- module search path; path[0] is the script directory, else ''
    modules -- dictionary of loaded modules
   
    displayhook -- called to show results in an interactive session
    excepthook -- called to handle any uncaught exception other than SystemExit
      To customize printing in an interactive session or to install a custom
      top-level exception handler, assign other functions to replace these.
   
    exitfunc -- if sys.exitfunc exists, this routine is called when Python exits
      Assigning to sys.exitfunc is deprecated; use the atexit module instead.
   
    stdin -- standard input file object; used by raw_input() and input()
    stdout -- standard output file object; used by the print statement
    stderr -- standard error object; used for error messages
      By assigning other file objects (or objects that behave like files)
      to these, it is possible to redirect all of the interpreter's I/O.
   
    last_type -- type of last uncaught exception
    last_value -- value of last uncaught exception
    last_traceback -- traceback of last uncaught exception
      These three are only available in an interactive session after a
      traceback has been printed.
   
    exc_type -- type of exception currently being handled
    exc_value -- value of exception currently being handled
    exc_traceback -- traceback of exception currently being handled
      The function exc_info() should be used instead of these three,
      because it is thread-safe.
   
    Static objects:
   
    maxint -- the largest supported integer (the smallest is -maxint-1)
    maxsize -- the largest supported length of containers.
    maxunicode -- the largest supported character
    builtin_module_names -- tuple of module names built into this interpreter
    version -- the version of this interpreter as a string
    version_info -- version information as a tuple
    hexversion -- version information encoded as a single integer
    copyright -- copyright notice pertaining to this interpreter
    platform -- platform identifier
    executable -- pathname of this Python interpreter
    prefix -- prefix used to find the Python library
    exec_prefix -- prefix used to find the machine-specific Python library
    dllhandle -- [Windows only] integer handle of the Python DLL
    winver -- [Windows only] version number of the Python DLL
    __stdin__ -- the original stdin; don't touch!
    __stdout__ -- the original stdout; don't touch!
    __stderr__ -- the original stderr; don't touch!
    __displayhook__ -- the original displayhook; don't touch!
    __excepthook__ -- the original excepthook; don't touch!
   
    Functions:
   
    displayhook() -- print an object to the screen, and save it in __builtin__._
    excepthook() -- print an exception and its traceback to sys.stderr
    exc_info() -- return thread-safe information about the current exception
    exc_clear() -- clear the exception state for the current thread
    exit() -- exit the interpreter by raising SystemExit
    getdlopenflags() -- returns flags to be used for dlopen() calls
    getprofile() -- get the global profiling function
    getrefcount() -- return the reference count for an object (plus one :-)
    getrecursionlimit() -- return the max recursion depth for the interpreter
    getsizeof() -- return the size of an object in bytes
    gettrace() -- get the global debug tracing function
    setcheckinterval() -- control how often the interpreter checks for events
    setdlopenflags() -- set the flags to be used for dlopen() calls
    setprofile() -- set the global profiling function
    setrecursionlimit() -- set the max recursion depth for the interpreter
    settrace() -- set the global debug tracing function
FUNCTIONS
    __displayhook__ = displayhook(...)
        displayhook(object) -> None
       
        Print an object to sys.stdout and also save it in __builtin__.
   
    __excepthook__ = excepthook(...)
        excepthook(exctype, value, traceback) -> None
       
        Handle an exception by displaying it with a traceback on sys.stderr.
   
    call_tracing(...)
        call_tracing(func, args) -> object
       
        Call func(*args), while tracing is enabled.  The tracing state is
        saved, and restored afterwards.  This is intended to be called from
        a debugger from a checkpoint, to recursively debug some other code.
   
    callstats(...)
        callstats() -> tuple of integers
       
        Return a tuple of function call statistics, if CALL_PROFILE was defined
        when Python was built.  Otherwise, return None.
       
        When enabled, this function returns detailed, implementation-specific
        details about the number of function calls executed. The return value is
        a 11-tuple where the entries in the tuple are counts of:
        0. all function calls
        1. calls to PyFunction_Type objects
        2. PyFunction calls that do not create an argument tuple
        3. PyFunction calls that do not create an argument tuple
           and bypass PyEval_EvalCodeEx()
        4. PyMethod calls
        5. PyMethod calls on bound methods
        6. PyType calls
        7. PyCFunction calls
        8. generator calls
        9. All other calls
        10. Number of stack pops performed by call_function()
   
    displayhook(...)
        displayhook(object) -> None
       
        Print an object to sys.stdout and also save it in __builtin__.
   
    exc_clear(...)
        exc_clear() -> None
       
        Clear global information on the current exception.  Subsequent calls to
        exc_info() will return (None,None,None) until another exception is raised
        in the current thread or the execution stack returns to a frame where
        another exception is being handled.
   
    exc_info(...)
        exc_info() -> (type, value, traceback)
       
        Return information about the most recent exception caught by an except
        clause in the current stack frame or in an older stack frame.
   
    excepthook(...)
        excepthook(exctype, value, traceback) -> None
       
        Handle an exception by displaying it with a traceback on sys.stderr.
   
    exit(...)
        exit([status])
       
        Exit the interpreter by raising SystemExit(status).
        If the status is omitted or None, it defaults to zero (i.e., success).
        If the status is numeric, it will be used as the system exit status.
        If it is another kind of object, it will be printed and the system
        exit status will be one (i.e., failure).
   
    getcheckinterval(...)
        getcheckinterval() -> current check interval; see setcheckinterval().
   
    getdefaultencoding(...)
        getdefaultencoding() -> string
       
        Return the current default string encoding used by the Unicode
        implementation.
   
    getfilesystemencoding(...)
        getfilesystemencoding() -> string
       
        Return the encoding used to convert Unicode filenames in
        operating system filenames.
   
    getprofile(...)
        getprofile()
       
        Return the profiling function set with sys.setprofile.
        See the profiler chapter in the library manual.
   
    getrecursionlimit(...)
        getrecursionlimit()
       
        Return the current value of the recursion limit, the maximum depth
        of the Python interpreter stack.  This limit prevents infinite
        recursion from causing an overflow of the C stack and crashing Python.
   
    getrefcount(...)
        getrefcount(object) -> integer
       
        Return the reference count of object.  The count returned is generally
        one higher than you might expect, because it includes the (temporary)
        reference as an argument to getrefcount().
   
    getsizeof(...)
        getsizeof(object, default) -> int
       
        Return the size of object in bytes.
   
    gettrace(...)
        gettrace()
       
        Return the global debug tracing function set with sys.settrace.
        See the debugger chapter in the library manual.
   
    getwindowsversion(...)
        getwindowsversion()
       
        Return information about the running version of Windows.
        The result is a tuple of (major, minor, build, platform, text)
        All elements are numbers, except text which is a string.
        Platform may be 0 for win32s, 1 for Windows 9x/ME, 2 for Windows NT/2000/XP
   
    setcheckinterval(...)
        setcheckinterval(n)
       
        Tell the Python interpreter to check for asynchronous events every
        n instructions.  This also affects how often thread switches occur.
   
    setprofile(...)
        setprofile(function)
       
        Set the profiling function.  It will be called on each function call
        and return.  See the profiler chapter in the library manual.
   
    setrecursionlimit(...)
        setrecursionlimit(n)
       
        Set the maximum depth of the Python interpreter stack to n.  This
        limit prevents infinite recursion from causing an overflow of the C
        stack and crashing Python.  The highest possible limit is platform-
        dependent.
   
    settrace(...)
        settrace(function)
       
        Set the global debug tracing function.  It will be called on each
        function call.  See the debugger chapter in the library manual.

NAME
    string - A collection of string operations (most are no longer used).
FILE
    c:\progra~1\sideef~1\houdin~1.572\python26\lib\string.py
DESCRIPTION
    Warning: most of the code you see here isn't normally used nowadays.
    Beginning with Python 1.6, many of these functions are implemented as
    methods on the standard string object. They used to be implemented by
    a built-in module called strop, but strop is now obsolete itself.
   
    Public module variables:
   
    whitespace -- a string containing all characters considered whitespace
    lowercase -- a string containing all characters considered lowercase letters
    uppercase -- a string containing all characters considered uppercase letters
    letters -- a string containing all characters considered letters
    digits -- a string containing all characters considered decimal digits
    hexdigits -- a string containing all characters considered hexadecimal digits
    octdigits -- a string containing all characters considered octal digits
    punctuation -- a string containing all characters considered punctuation
    printable -- a string containing all characters considered printable

        Return the integer represented by the string s in the given
        base, which defaults to 10.  The string s must consist of one
        or more digits, possibly preceded by a sign.  If base is 0, it
        is chosen from the leading characters of s, 0 for octal, 0x or

        given base, which defaults to 10.  The string s must consist
        of one or more digits, possibly preceded by a sign.  If base
        is 0, it is chosen from the leading characters of s, 0 for
        octal, 0x or 0X for hexadecimal.  If base is 16, a preceding
        0x or 0X is accepted.  A trailing L or l is not accepted,
        unless base is 0.

        capitalized.
   
    capwords(s, sep=None)
        capwords(s [,sep]) -> string
       
        Split the argument into words using split, capitalize each
        word using capitalize, and join the capitalized words using
        join.  If the optional second argument sep is absent or None,
        runs of whitespace characters are replaced by a single space
        and leading and trailing whitespace are removed, otherwise
        sep is used to split and join the words.
   
    center(s, width, *args)
        center(s, width[, fillchar]) -> string
       
        Return a center version of s, in a field of the specified
        width. padded with spaces as needed.  The string is never
        truncated.  If specified the fillchar is used instead of spaces.
   
    count(s, *args)
        count(s, sub[, start[,end]]) -> int
       
        Return the number of occurrences of substring sub in string

        Return a copy of the string s with all tab characters replaced
        by the appropriate number of spaces, depending on the current
        column, and the tabsize (default 8).
   
    find(s, *args)
        find(s, sub [,start [,end]]) -> in
       
        Return the lowest index in s where substring sub is found,
        such that sub is contained within s[start,end].  Optional

        Return -1 on failure.
   
    index(s, *args)
        index(s, sub [,start [,end]]) -> int
       
        Like find but raises ValueError when the substring is not found.
   
    join(words, sep=' ')
        join(list [,sep]) -> string
       
        Return a string composed of the words in list, with
        intervening occurrences of sep.  The default separator is a
        single space.
       
        (joinfields and join are synonymous)
   
    joinfields = join(words, sep=' ')
        join(list [,sep]) -> string
       
        Return a string composed of the words in list, with
        intervening occurrences of sep.  The default separator is a
        single space.

        Return a copy of the string s converted to lowercase.
   
    lstrip(s, chars=None)
        lstrip(s [,chars]) -> string
       
        Return a copy of the string s with leading whitespace removed.
        If chars is given and not None, remove characters in chars instead.
   
    maketrans(...)
        maketrans(frm, to) -> string
       
        Return a translation table (a string of 256 bytes long)
        suitable for use in string.translate.  The strings frm and to
        must be of the same length.

        replace (str, old, new[, maxsplit]) -> string
       
        Return a copy of string str with all occurrences of substring
        old replaced by new. If the optional argument maxsplit is
        given, only the first maxsplit occurrences are replaced.
   
    rfind(s, *args)
        rfind(s, sub [,start [,end]]) -> int
       
        Return the highest index in s where substring sub is found,
        such that sub is contained within s[start,end].  Optional

        Return -1 on failure.
   
    rindex(s, *args)
        rindex(s, sub [,start [,end]]) -> int
       
        Like rfind but raises ValueError when the substring is not found.
   
    rjust(s, width, *args)
        rjust(s, width[, fillchar]) -> string
       
        Return a right-justified version of s, in a field of the
        specified width, padded with spaces as needed.  The string is
        never truncated.  If specified the fillchar is used instead of spaces.

        rsplit(s [,sep [,maxsplit]]) -> list of strings
       
        Return a list of the words in the string s, using sep as the
        delimiter string, starting at the end of the string and working
        to the front.  If maxsplit is given, at most maxsplit splits are
        done. If sep is not specified or is None, any whitespace string
        is a separator.
   
    rstrip(s, chars=None)
        rstrip(s [,chars]) -> string

        Return a list of the words in the string s, using sep as the
        delimiter string.  If maxsplit is given, splits at no more than
        maxsplit places (resulting in at most maxsplit+1 words).  If sep
        is not specified or is None, any whitespace string is a separator.
       
        (split and splitfields are synonymous)
   
    splitfields = split(s, sep=None, maxsplit=-1)
        split(s [,sep [,maxsplit]]) -> list of strings
       
        Return a list of the words in the string s, using sep as the
        delimiter string.  If maxsplit is given, splits at no more than
        maxsplit places (resulting in at most maxsplit+1 words).  If sep
        is not specified or is None, any whitespace string is a separator.
       
        (split and splitfields are synonymous)
   
    strip(s, chars=None)
        strip(s [,chars]) -> string
       
        Return a copy of the string s with leading and trailing
        whitespace removed.

        If chars is unicode, S will be converted to unicode before stripping.
   
    swapcase(s)
        swapcase(s) -> string
       
        Return a copy of the string s with upper case characters
        converted to lowercase and vice versa.
   
    translate(s, table, deletions='')
        translate(s,table [,deletions]) -> string
       
        Return a copy of the string s, where all characters occurring
        in the optional argument deletions are removed, and the

pwd
ls -al
cd 디렉토리명

cat 파일이름.py
(ex: cat p(tab키 누르면 자동 완성))(.py파일 실행)

chmod +x 파일이름.py 를 하면 py파일을 실행 파일로 바꿔준다.
./파일이름.py 아니면 전체경로/파일이름.py

리눅스 cd 명령어 사용법

1. 기능 Change Directory. 현재 작업하는 디렉토리를 변경한다. 2. 문법 # cd 디렉토리 3. 옵션 . : 현재 디렉토리 .. : 상위 디렉토리 ~ : 홈디렉토리 - : 이전 디렉토리로 이동 4. 사용방법 및 정보 디렉토리 이름과 cd 명령 사이에 반드시 공백이 있어야 한다. 디렉토리 이름을 주지 않고 수행하면 사용자의 홈 디렉토리로 이동한다. 자신이 이동하고자 하는 디렉토리는 자신에게 실행 권한(execution permission)이 있어야 한다. 실행 결과는 ‘pwd’ 명령을 통해 확인할 수 있다. [root@sense ~]# cd /etc/sysconfig : /etc/sysconfig 디렉토리로 이동 [root@sense sysconfig]# pwd : 현재 디렉토리 확인 /etc/sysconfig [root@sense sysconfig]# cd ../.. : 두 단계 상위의 디렉토리로 이동 [root@sense /]# cd : 홈디렉토리로 이동 [root@sense ~]# pwd : 현재 디렉토리 확인 /root [root@sense ~]# cd - : 이전 작업 디렉토리로 이동 /

Linux에서 Python 설치

Linux에서 Python 설치

Linux에는 기본적으로 Python이 설치되어있지만, 버젼이 맞지않을경우에 특별한 버젼의 파이썬을 다운로드하고 설치를 해야합니다.

1. Python 실행 파일 위치 및 버젼 알기

which python --> /usr/bin/python
python -V --> 3.2.x

2. 설치하고 싶은 버젼의 tar 파일을 Linux 컴퓨터에 저장(http://python.org/download/)

3. tar 파일 압축 풀기

tar -zxvf Python-2.7.3.tar

http://psjin14.tistory.com&embedCodeSrc=http%3A%2F%2Fpsjin14.tistory.com%2Fplugin%2FCallBack_bootstrapper%3F%26src%3Dhttp%3A%2F%2Fs1.daumcdn.net%2Fcfs.tistory%2Fv%2F0%2Fblog%2Fplugins%2FCallBack%2Fcallback%26id%3D7%26callbackId%3Dpsjin14tistorycom79857%26destDocId%3Dcallbacknestpsjin14tistorycom79857%26host%3Dhttp%3A%2F%2Fpsjin14.tistory.com%26float%3Dleft" swliveconnect="true">

4. Python 설치

압축 해제된 폴더 내에서, 다음 명령어를 실행한다.

1) ./configure
2) make
3) make install

코드를 컴파일하고, 설치를 한다.

5. Symbolic Link를 통해 원하는 버젼의 파이썬을 링크를 걸어줘야 한다.

1) 기존의 /usr/bin/python는 지워준다.

ex) sudo rm /usr/bin/python

2) Symbolic Link 걸기

ln -s /usr/bin/Python2.7 /usr/bin/python

MAYA Python

MAYA PYTHON
-------------------------------------------------------------------------
 print u'하이 MAYA'
#유니코드를 사용하기 때문에 앞에 u를 붙인다.



import sys
print sys.version
을 치면 버전 정보가 print된다.


a=1 을 치고 a를 치면 1이 뜬다.

하지만

a=1
a
를 치게 되면, 그냥
a=1
a
가 뜬다. 왜냐하면, 한줄 이상을 입력하게 되면 대화형이 아닌 script모드로 바로 전환되기 때문이다. 그래서 a값이 바로 반환되지는 않는다..

아니면 원하는 부분만 블록 지정을 한뒤, execute를 실행해도 된다.





-Python Module Path 확인/추가하기

import sys
print sys.path
그럼 시스템경로가 print된다.

만약 c:\\myModle이라는 폴더에 python스크립트가 있으면,
import sys
sys.path.append('c:\\myModule\\')
로 경로를 추가한다..






-import maya.cmds as cmds

import maya.cmds as cmds
print cmds.ls( selection=True )
를 치면 선택한 obj가 프린트가 된다.

as 처럼...,~~로써
maya.cmds라는 module을 cmds라는 이름으로 불러오는 명령..
즉, maya.cmds라는 명령을 cmds로 바꿔서 명령을 수행하게 된다..
import maya.cmds as cmds
maya.cmds를 자주 쓰기 때문에, cmds로 짧게 바꾼 것 뿐이다..

따라서import maya.cmds as m을 쓰면
import maya.cmds as m
print m.ls( selection=True )
를 치면 똑같이 프린트가 된다.

그리고 import를 한 번만 읽어도 게속 사용이 가능하다..즉,
cmds.ls(selection=True)
m.ls( selection=True )
를 치면 똑같이 선택된 obj를 보여준다.

하지만
cmds.ls(selection=True)
cmds.ls(selection=True)
두번을 똑같은걸 치면
보이지 않는다. 왜냐하면 대화형 모드와 script모드의 차이 때문이다..






-select,wildcard
nurbsCone obj를 그리드에 맞춰 25개를 만든다.
import maya.cmds as cmds
cmds.select(all=True)
를 치면 전체가 선택이 된다.

cmds.select('*')
를 치면 결과는 똑같다.

cmds.select('nurbsCone1?')
를 치면 10~19까지 Cone이 선택된다.

cmds.select('nurbsCone1', 'nurbsCone2','nurbsCone3')
적힌 nurbsCone만 선택이 된다.

sel_obj = cmds.ls(sl=1)
cmds.select(clear=1)
를 치면 sel_obj라는 변수에 select된 목록 자료를 담고, 현재 select를 해제하였습니다.

sel_obj = cmds.ls(sl=1)명령은 sel_obj에 지금 선택한 목록을 저장하라는 명령니 된다.
sl=1은 sl=True와 같다.(python command에서 ls를 검색)(ls의 sl차입이 boolean이라서..)

sel_obj
를 치면 선택했던 obj이름이 뜬다.

obj왜에 node들도 가능하다..





-Python Sequence자료 다루기
노드나, 오브젝트를 선택
import maya.cmds as cmds
sel_=cmds.ls(sl=1)
를 치면 sle_이라는 변수에 선택된 노드를 저장한다.

sel_
를 치면 선택된 이름들이 리스트형으로 나온다.

cmds.select(sel_[0])
를 치면 0번째 node가 선택이 된다. 인덱싱.리스트자료에서 0번째

cmds.select(sel_[-1])
를 치면 마지막 node가 선택

cmds.select(sel_[:10])
를 치면 앞에서 부터 10개만 선택이 된다.

cmds.select(sel_[-10:])
를 치면 뒤에서부터 10개 선택이 된다.

cmds.select(sel_[5:15])
를 치면 5번째 부터 15번째 까지 선택

cmds.select(sel_[::2])
를 치면 한칸씩 건너뛰면서 선택








-Python Sequence자료 다루기-2
len(sel_)
를 치면 len모듈을 쳤기 때문에 자료의 계수 숫자가 나온다.

sel_.count('nurbsCone14')
를 치면 nurbsCone14의 계수를 보여준다.

sel_.index('nurbsCone14')
를 치면 리스트 자료상에서 몇번째에 있는지 알 수 있다.

sel_.remove('nurbsCone14')
를 치면 nurbsCone14가 지워진다.sel_을 쳐서 확인

del sel_[3]
를 치면 리스트 자료 중에 3번째가 지워진다.

sel_.append(u'nurbsCone14')
sel_
를 치면 append모듈로 sel_리스트에 'NURBSCone14'를 추가한다.

sel_.insert(3, u'nurbsCone14')
sel_
를 치면 3위치에 삽입이 된다.

sel_.count('nurbsCone14')
를 치면 nurbsCone14의 계수가 나온다.

sel_[3:3] = [u'nurbsCone14']
sel_
를 치면 3:3인덱싱 위치에 삽입한다.

sel_+= [u'nurbsCone14']
sel_
를 쳐도 삽입이 된다.

sel_.sort()
를 치면 이름 순서대로 리스트를 정리 한다.

sel_.reverse()
sel_
를 치면 reverse()모듈를 이용해 리스트의 순서를 반전 시킨다.

sel_.extend([u'노드',u'노드',u'노드',u'노드'들....])
sel_
를 치면 자료와 자료를 합친다.

sel_ +=[u'노드',u'노드',u'노드',u'노드'들....]
를 치면 이 역시 자료와 자료를 합친다.

sel_

'nurbsCone18' in sel_
를 치면 sel_변수안에 'nurbsCone18'가 있는지 검사
