Invocation Options 起動オプション
(シェルで実行。>>>の表示はインタプリタ起動中。)
### -d
Output parser debugging information (also PYTHONDEBUG=x)
G5:~ username$ python -d Python 2.5.1 (r251:54869, Apr 18 2007, 22:08:04) [GCC 4.0.1 (Apple Computer, Inc. build 5367)] on darwin Type "help", "copyright", "credits" or "license" for more information. >>>
?
### -E
Ignore environment variables (such as PYTHONPATH)
G5:~ username$ python -E Python 2.5.1 (r251:54869, Apr 18 2007, 22:08:04) [GCC 4.0.1 (Apple Computer, Inc. build 5367)] on darwin Type "help", "copyright", "credits" or "license" for more information. >>>
?
### -h
Print a help message and exit (formerly -?)
G5:~ username$ python -h usage: /Library/Frameworks/Python.framework/Versions/2.5/Resources/Python.app/Contents/MacOS/Python [option] ... [-c cmd | -m mod | file | -] [arg] ... Options and arguments (and corresponding environment variables): -c cmd : program passed in as string (terminates option list) -d : debug output from parser (also PYTHONDEBUG=x) -E : ignore environment variables (such as PYTHONPATH) -h : print this help message and exit (also --help) -i : inspect interactively after running script, (also PYTHONINSPECT=x) and force prompts, even if stdin does not appear to be a terminal -m mod : run library module as a script (terminates option list) -O : optimize generated bytecode (a tad; also PYTHONOPTIMIZE=x) -OO : remove doc-strings in addition to the -O optimizations -Q arg : division options: -Qold (default), -Qwarn, -Qwarnall, -Qnew -S : don't imply 'import site' on initialization -t : issue warnings about inconsistent tab usage (-tt: issue errors) -u : unbuffered binary stdout and stderr (also PYTHONUNBUFFERED=x) see man page for details on internal buffering relating to '-u' -v : verbose (trace import statements) (also PYTHONVERBOSE=x) -V : print the Python version number and exit (also --version) -W arg : warning control (arg is action:message:category:module:lineno) -x : skip first line of source, allowing use of non-Unix forms of #!cmd file : program read from script file - : program read from stdin (default; interactive mode if a tty) arg ...: arguments passed to program in sys.argv[1:] Other environment variables: PYTHONSTARTUP: file executed on interactive startup (no default) PYTHONPATH : ':'-separated list of directories prefixed to the default module search path. The result is sys.path. PYTHONHOME : alternate <prefix> directory (or <prefix>:<exec_prefix>). The default module search path uses <prefix>/pythonX.X. PYTHONCASEOK : ignore case in 'import' statements (Windows).
### -i
Inspect interactively after running script (also PYTHONINSPECT=x) and force prompts, even if stdin appears not to be a terminal.
下準備として、ファイルprint.pyを作成して「print "I love Python!"」と書いて保存しておく。(現在作業中のディレクトリに)
G5:~ username$ python -i Python 2.5.1 (r251:54869, Apr 18 2007, 22:08:04) [GCC 4.0.1 (Apple Computer, Inc. build 5367)] on darwin Type "help", "copyright", "credits" or "license" for more information. >>> G5:~ username$ python -i print.py I love Python! >>>
### -m module
Search for module on sys.path and runs the module as a script. (Implementation improved in 2.5: module runpy)
G5:~ username$ python -m print
I love Python!
### -O
Optimize generated bytecode (also PYTHONOPTIMIZE=x). Asserts are suppressed.
保留(´・ω・`)
### -OO
Remove doc-strings in addition to the -O optimizations.
保留(´・ω・`)
### -Q arg
Division options: -Qold (default), -Qwarn, -Qwarnall, -Qnew
保留(´・ω・`)
### -S
Don't perform import site on initialization.
保留(´・ω・`)
### -t
Issue warnings about inconsistent tab usage (-tt: issue errors).
保留(´・ω・`)
### -u
Unbuffered binary stdout and stderr (also PYTHONUNBUFFERED=x).
保留(´・ω・`)
### -v
Verbose (trace import statements) (also PYTHONVERBOSE=x).

### -W arg
Warning control (arg is action:message:category:module:lineno)
保留(´・ω・`)
### -x
Skip first line of source, allowing use of non-unix Forms of #!cmd
保留(´・ω・`)
### -c command
Specify the command to execute (see next section). This terminates the option list (following options are passed as arguments to the command).
保留(´・ω・`)
### scriptFile
The name of a python file (.py) to execute. Read from stdin.
G5:~ username$ python print.py
I love Python!
### -
Program read from stdin (default; interactive mode if a tty).
保留(´・ω・`)
### args
Passed to script or command (in sys.argv[1:])
下準備として現在作業中のディレクトリにargv_hoge.pyファイルを作成し以下を書き込む。
import sys for i in sys.argv[1:]: print i
実行と結果
G5:~ username$ python argv_hoge.py 1 2 3 1 2 3 G5:~ username$ python argv_hoge.py "a" "b" "c" a b c
###
If no scriptFile or command, Python enters interactive mode.

補足
というか言い訳。
起動オプションなんて普段使わないから、よくわからず保留多し(´・ω・`)。そのうち...
