Match a word containing ‘z’

pattern = ‘w*z.w*’

Write a python program that matches a word containing ‘z’.
import re

def text_match(S):

    pattern = '\w*z.\w*'

    if re.search(pattern, S):
        return 'Found a match!'
    else:
        return('Not matched!')

# test
print(text_match("The quick brown fox jumps over the lazy dog."))
print(text_match("Python Exercises."))

Output:

Found a match!
Not matched!
