python regex to detect a word exists

Question

I want to detect whether a word is in a sentence using python regex. Also, want to be able to negate it.

import re
re.match(r\'(?=.*\\bfoo\\b)\', \'bar red f         


        

Answer 1

You need the .* because re.match() tries to match the pattern to the beginning of the string. If you want to search the whole string, use re.search().

Just as you can do if re.search(...):, you can also do if not re.search(...):
