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','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。
