python的keyword模块用法实例分析

本文实例讲述了python的keyword模块用法。分享给大家供大家参考。具体如下：

    Help on module keyword:
    NAME
      keyword - Keywords (from "graminit.c")
    FILE
      /usr/lib64/python2.6/keyword.py
    DESCRIPTION
      This file is automatically generated; please don't muck it up!
      To update the symbols in this file, 'cd' to the top directory of
      the python source tree after building the interpreter and run:
        python Lib/keyword.py
    FUNCTIONS
      iskeyword = __contains__(...)
        x.__contains__(y) <==> y in x.
    DATA
      __all__ = ['iskeyword', 'kwlist']
      kwlist = ['and', 'as', 'assert', 'break', 'class', 'continue', 'def', ...

得到python的关键字列表：

    >>> keyword.kwlist
    ['and', 'as', 'assert', 'break', 'class', 'continue', 'def', 'del', 'elif', 'else', 'except', 'exec', 'finally', 'for', 'from', 'global', 'if', 'import', 'in', 'is', 'lambda', 'not', 'or', 'pass', 'print', 'raise', 'return', 'try', 'while', 'with', 'yield']

判断字符串是否是python的关键字

    >>> keyword.iskeyword('and')
    True
    >>> 
    >>> keyword.iskeyword('has')
    False

希望本文所述对大家的Python程序设计有所帮助。
