使用Python的正则表达式(regex)模块re可以获取字符串的前两个数字。下面是一个完善且全面的答案: 正则表达式是一种强大的模式匹配工具,可以用于在字符串中查找、替换和提取特定的文本模式。Python的re模块提供了对正则表达式的支持。 要获取字符串的前两个数字,可以使用以下步骤: 导入re模块:在Python代码中,首...
A Match Object is an object containing information about the search and the result. Note:If there is no match, the valueNonewill be returned, instead of the Match Object. Example Do a search that will return a Match Object: importre ...
importreprint(re.match('com','comwww.runcomoob').group())print(re.match('com','Comwww.runcomoob',re.I).group()) 6、search() 格式: re.search(pattern, string, flags=0) re.search函数会在字符串内查找模式匹配,只要找到第一个匹配然后返回,如果字符串没有匹配,则返回None。
