二、预定义字符 如果每次都通过代码来验证正则表达式是否正确效率有点低,我们可以通过在线工具来校验我们的正则表达式是否正确,比如oschina的在线正则表达式测试工具;当然在Windows系统下可以使用RegexBuddy工具进行检测。 普通字符:字母、数字、下划线以及没有特殊意义的符号,都是普通字符。 元字符:这里主要有11个构成正则表...

1)re.compile() 该方法用来生成正则表达式对象,其语法格式如下: regex=re.compile(pattern,flags=0)1复制代码类型:[python] 参数说明: pattern:正则表达式对象。 flags:代表功能标志位,扩展正则表达式的匹配。 2)re.findall() 根据正则表达式匹配目标字符串内容。
