Write a Python function that checks if a given string contains the letter `a` followed by exactly three `b` characters. The function should return `True` if the pattern is found and `False` otherwise. #### Example Usage ```python [main.nopy] text_match_three("abbb") # True text_match_three("a") # False text_match_three("abbbb") # False text_match_three("cabbbd") # True ``` #### Constraints - Use regular expressions to solve the problem. - The function should return a boolean value indicating whether the pattern is found.
import re def text_match_three(text): """ Check if the input string contains 'a' followed by exactly three 'b' characters. Args: text (str): The input string to check. Returns: bool: True if the pattern is found, False otherwise. """ # Define the regular expression pattern pattern = '' # TODO: Complete the pattern # Use re.search to find the pattern in the text return bool(re.search(pattern, text))
