Python中re正则表达式的问题

Question

str1 = 'universe  ['juːnɪvɜːs]'

请问下各位，怎么用正则表达式匹配 ['juːnɪvɜːs]

使之替换成空，最后的结果是：str1 = 'universe'

恳请各位不吝赐教，不胜感激。

Answer 1

The answer above needs to be slightly modified. Regular Chinese square brackets [ ] themselves have grammatical meaning, so they need to be escaped. Just change it to this.

pythonimport re
str1 = re.sub(r'\[.*\]', '', "universe ['juːnɪvɜːs]")

The official description of the python re module is as follows:

https://docs.python.org/2/library/re.html

Sometimes you forget to check the regular rules, they are quite detailed.

Answer 2

import re
str1 = re.sub(r'\[.*\]', '', "universe  ['juːnɪvɜːs]")

Segmentfaults seems to automatically [escape to [, which forces me to use code blocks.
