Check if list items contains substrings from another list

Question

I have a lists:

my_list = [\'abc-123\', \'def-456\', \'ghi-789\', \'abc-456\', \'def-111\', \'qwe-111\']

bad = [\'abc\', \'def\']

and want

Answer 1

some_list = ['abc-123', 'def-456', 'ghi-789', 'abc-456']
bad = ['abc', 'def']
for s in some_list:
    for item in bad:
       if item in s:
          print 'Found ', s

It's simple, works fine and fast( only if your list is not very big.)
