python regular expression re compile

Once you have the compiled regex object, you can use it for various operations such as matching, searching, or substitution.
In this example, the match() method is used to check if the string '123-45-6789' matches the SSN pattern. If there is a match, it prints "Match found!", otherwise, it prints "No match."
The search() method is used to find the first occurrence of the pattern in the given text. If a match is found, it prints the matched SSN.
