python - 从字符串中提取方括号文本

Question

有人可以帮我从字符串中删除字符，只留下“[....]”中的字符吗？

For example:

a  = newyork_74[mylocation]

b = # strip the frist characters until you reach the first bracket [

c = [mylocation]

Answer 1

类似这样的事情:

>>> import re
>>> strs = "newyork_74[mylocation]"
>>> re.sub(r'(.*)?(\[)','\g<2>',strs)
'[mylocation]'
