匹配python正则表达式中的括号 [英] matching parentheses in python regular expression

问题描述

我有类似的东西

商店

结束行如 1 个商店 ..我想匹配，它使用 python 正则表达式.

ending line like 1 store(s) .. I want to match , it using python regular expression.

我尝试了类似 re.match('store\(s\)$',text)但它不起作用.

I tried something like re.match('store\(s\)$',text) but it's not working .

添加代码，我试过

import re
s = '1 store(s)'
if re.match('store\(s\)$',s) :
    print('match')

请帮忙.

谢谢极乐

试试这个

import re
s = '1 stores(s)'
if re.match('store\(s\)$',s):
    print('match')

解决方案是使用 re.search 而不是 re.match 因为后者试图用正则表达式匹配整个字符串，而前者只是试图找到一个与表达式匹配的字符串内的子字符串.

The solution is to use re.search instead of re.match as the latter tries to match the whole string with the regexp while the former just tries to find a substring inside of the string that does match the expression.
