def phoneNumberFormat(phoneNum):
    if len(phoneNum) != 10:
        print('Error. Length of phone number is not 10.')
    else:
        areaCode = phoneNum[:3]
        next3digits = phoneNum[3:6]
        last4digits = phoneNum[6:]
        result = '(' + areaCode + ')' + next3digits + '-' + last4digits
        print(result)


phoneNumberFormat('5155551212')
