How to input a regex in string.replace?

Question

I need some help on declaring a regex. My inputs are like the following:

this is a paragraph with<[1> in between and then there are cases ..         


        

Answer 1

replace method of string objects does not accept regular expressions but only fixed strings (see documentation: http://docs.python.org/2/library/stdtypes.html#str.replace).

You have to use re module:

import re
newline= re.sub("<\/?\[[0-9]+>", "", line)
