的内容,
I'm trying to remove wiki formatting from some text so it can be parsed.
What is the most pythonic way to remove two delimiters ('[[' and ']]') all the text between them? The given string will contain multiple occurrences of delimiter pairs.
解决方案
Regular expressions are a good match for your problem.
>>> import re
>>> input_str = 'foo [[bar]] baz [[etc.]]'
If you are wanting to remove the whole [[...]]
, which is I think what you are asking about,
>>> re.sub(r'\[\[.*?\]\]', '', input_str)
'foo baz '
If you are wanting to leave the contents of the [[...]]
in,
>>> re.sub(r'\[\[(.*?)\]\]', r'\1', input_str)
'foo bar baz etc.'
