python .replace() regex [duplicate]

No. Regular expressions in Python are handled by the re module.
article = re.sub(r'(?is).+’, ‘‘, article)

In general:
text_after = re.sub(regex_search_term, regex_replacement, text_before)

In order to replace text using regular expression use the re.sub function:

sub(pattern, repl, string[, count, flags])

It will replace non-everlaping instances of pattern by the text passed as string. If you need to analyze the match to extract information about specific group captures, for instance, you can pass a function to the string argument. more info here.
Examples
>>> import re
>>> re.sub(r’a’, ‘b’, ‘banana’)
‘bbnbnb’

>>> re.sub(r’/d+’, ‘/{id}’, ‘/andre/23/abobora/43435’)
‘/andre/{id}/abobora/{id}’
