Re: 字符串中的查找问题

The re <file:///D:/Users/cn1ll290/Desktop/python/lib/module-re.html> module
provides regular expression tools for advanced string processing. For
complex matching and manipulation, regular expressions offer succinct,
optimized solutions:

re <file:///D:/Users/cn1ll290/Desktop/python/lib/module-re.html>模块为高级字符串处理提供了正则表达式工具。对于复杂的匹配和处理，正则表达式提供了简洁、优化的解决方案。

>>> import re
>>> re.findall(r'\bf[a-z]*', 'which foot or hand fell fastest')
['foot', 'fell', 'fastest']
>>> re.sub(r'(\b[a-z]+) \1', r'\1', 'cat in the the hat')
'cat in the hat'

 When only simple capabilities are needed, string methods are preferred
because they are easier to read and debug:

如果只需要简单的功能，应该首先考虑字符串方法，因为它们非常简单，易于阅读和调试。

>>> 'tea for too'.replace('too', 'two')
'tea for two'
