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

Question

Lets say I have a list of strings,

string_lst = [\'fun\', \'dum\', \'sun\', \'gum\']

I want to make a regular expression, where at a point

Answer 1

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

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

You cannot use match as it will match from start.Use findall instead.

Output:['fun']

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.
