python正则表达式：匹配第一个“}”

Question

我有一个字符串s，其中包含： -

Hello {full_name} this is my special address named {address1}_{address2}.

我正在尝试匹配大括号中包含的所有字符串实例。

尝试： -

matches = re.findall(r'{.*}', s)

给了我

['{full_name}', '{address1}_{address2}']

但我实际上想要检索的是

['{full_name}', '{address1}', '{address2}']

我该怎么做？

Answer 1

>>> import re
>>> text = 'Hello {full_name} this is my special address named {address1}_{address2}.'
>>> re.findall(r'{[^{}]*}', text)
['{full_name}', '{address1}', '{address2}']

Answer 2

尝试非贪婪的比赛：

matches = re.findall(r'{.*?}', s)

Answer 3

你需要一个非贪婪的量词：

matches = re.findall(r'{.*?}', s)

请注意问号?。
