    mlzboy@mlzboy-mac:/usr/local/nginx$ python --help
    usage: python [option] ... [-c cmd | -m mod | file | -] [arg] ...
    Options and arguments (and corresponding environment variables):
    -B     : don't write .py[co] files on import; also PYTHONDONTWRITEBYTECODE=x
    -c cmd : program passed in as string (terminates option list)
    -d     : debug output from parser; also PYTHONDEBUG=x
    -E     : ignore PYTHON* environment variables (such as PYTHONPATH)
    -h     : print this help message and exit (also --help)
    -i     : inspect interactively after running script; forces a prompt even
             if stdin does not appear to be a terminal; also PYTHONINSPECT=x
    -m mod : run library module as a script (terminates option list)
    -O     : optimize generated bytecode slightly; 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 add user site directory to sys.path; also PYTHONNOUSERSITE
    -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
             can be supplied multiple times to increase verbosity
    -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
    -3     : warn about Python 3.x incompatibilities that 2to3 cannot trivially fix
    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).
    PYTHONIOENCODING: Encoding[:errors] used for stdin/stdout/stderr.
