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
