Can I get some clarification on the re module specifically on matching
string

Line 137 of the Re module

def match(pattern, string, flags=0):
    """Try to apply the pattern at the start of the string, returning
    a match object, or None if no match was found."""
    return _compile(pattern, flags).match(string)
