def matchsix(string):
    temp = re.compile(r"^6")
    if temp.match(string):
        return True
    else:
        return False

    #must have .* before suffix and $
    temp = re.compile(r".*ism$")

        return True
    else:
        return False

    #checks for a number at the end of a string.
    temp = re.compile(r".*[0-9]$")
    if temp.match(string):
        return True
    else:
