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
