9. a ... ending in b

Write a Python program that matches a string that has an 'a' followed by anything ending in 'b'.

Sample Solution:

Python Code:

import re
def text_match(text):
        patterns = 'a.*?b$'
        if re.search(patterns,  text):
                return 'Found a match!'
        else:
                return('Not matched!')

print(text_match("aabbbbd"))
print(text_match("aabAbbbc"))
print(text_match("accddbbjjjb"))

Sample Output:

Not matched!                                                                                                  
Not matched!                                                                                                  
Found a match!
