Loosely searching multiple words in a sentence using python

I am trying to search words in a string but my output is false because "men" and "shirt" does not match in the string because of plural factor. What i am really looking for is to match "men" with "mens" and "shirt" with "shirts". How can I do that and if there is a easy way to accomplish this in python then please share.

strings = ['get-upto-70-off-on-mens-t-shirts']
words = ['men','shirt']
print map(lambda x: all(map(lambda y:y in x.split(),words)),strings)

Output

False

One possibility is using Python's builtin difflib module. The function get_close_matches() (doc) might need some tuning:

import difflib

strings = ['get-upto-70-off-on-mens-t-shirts']
words = ['men','shirt']

for w in words:
    for s in strings:
        s = s.split('-')
        m = difflib.get_close_matches(w, s)
        print('Word: "{}" Close matches: {}'.format(w, m))

Prints:

Word: "men" Close matches: ['mens']
Word: "shirt" Close matches: ['shirts']

You can either use lemmatization in NTLK library (remove 's' 'ing' etc) or Fuzzy String Match using FUZZYWUZZY library.
