How to match any string from a list of strings in regular expressions in python?

by

Join the list on the pipe character |, which represents different options in regex.

string_lst = ['fun', 'dum', 'sun', 'gum']
x="I love to have fun."

print re.findall(r"(?=("+'|'.join(string_lst)+r"))", x)

Output: ['fun']

You cannot use match as it will match from start.
Using search you will get only the first match. So use findall instead.

Also use lookahead if you have overlapping matches not starting at the same point.
