Check if multiple strings exist in another string

Question

How can I check if any of the strings in an array exists in another string?

Like:

a = ['a', 'b', 'c']

str = "a123"

if a in str:

print "some of the strings found in str"

else:

print "no strings found in str"

That code doesn't work, it's just to show what I want to achieve.

Answer 1

If you want to check whether any of the strings in an array exists in another string or not you can use the keyword ‘any’ below is an example that shows how to use any keyword:-

if any(x in str for x in a):

Another thing you can do is to use the regular expression:-

import re

if any(re.findall(r'a|b|c', str, re.IGNORECASE)):

print('possible matches found')

else:

print('no matches')
