6. a Followed by 2 to 3 b's

Write a Python program that matches a string that has an a followed by two to three 'b'.

Sample Solution:

Python Code:

import re
def text_match(text):
        patterns = 'ab{2,3}'
        if re.search(patterns,  text):
                return 'Found a match!'
        else:
                return('Not matched!')
print(text_match("ab"))
print(text_match("aabbbbbc"))

Sample Output:

Not matched!
Found a match!
