python - python中的正则表达式:findall

re.findall(r'[\w]+@+[\w.]','blahh [email protected] yipee']

返回['ggg@g']

为什么不返回['[email protected]']或至少返回['ggg@google']？

最佳答案

\w+@+[\w.]+

         ^^

您未能添加一个量词，因此@之后只能得到一个字符。

它应该是

`re.findall(r'[\w]+@+[\w.]+','blahh [email protected] yipee')`

另外，如果只能有一个@，则可以删除其前面的量词以使其成为\w+@[\w.]+

输出：['[email protected]']
