Python正则表达式语法错误 [英] Python regular expression syntax error

问题描述

我正在尝试编写一个正则表达式来匹配 -(破折号)，后跟尽可能多的字母.我目前拥有的是以下内容:exp = (-[a-z A-z]*).
我收到一个 SyntaxError: invalid syntax 错误.

I am trying to write a regular expression that will match a - (dash), followed by as many letters as it possibly can. What I have at the moment, is the following: exp = (-[a-z A-z]*).
I am getting a SyntaxError: invalid syntax error though.

推荐答案

尝试将表达式放入字符串中

try placing your expression in a string

import re
exp = re.compile('(-[a-z A-z]*)')
