Use Customer class remove the address attribute.Place the code in Module12 project package custom_exceptions, file customer_exceptions.py. Include your directory for test_custom_exceptions and test_customer_exceptions.py Make exception for the following attributes: customer_id -a number between 1000-9999, InvalidCustomerIdException last_name - alpha characters, InvalidNameException first_name -alpha characters, InvalidNameException phone_number - 123-123-1234 format, InvalidPhoneNumberFormat Include driver code that tests the exceptions with try/except include calls for constructor with invalid customer_id constructor with invalid last_name constructor with invalid first_name constructor with invalid phone_number str() Include unit test to test the code setUp() tearDown() constructor with invalid customer_id constructor with invalid last_name constructor with invalid first_name constructor with invalid phone_number str() test(s)
Homework Answers
You will have to use regular expressions to validate the scenarios.
- ^[0-9]+$ to validate that customer id contain only digits. You can create complex regular expression to validate whether the number is between 1000-9999
- ^[A-Za-z]+$ to validate that the name contain only alphabets, not even blank space
- ^[0-9]{3}\-[0-9]{3}\-[0-9]{4}$ to verify the phone number contains only numbers and is in proper format. This will allow user to enter a phone number "000-000-0000". A lengthy, but not so complex, regular expression can be written to validate this too.
import re
class Customer:
def __init__(self, customer_id, last_name, first_name, phone_number):
if re.match("^[0-9]+$",customer_id):
if not int(customer_id) in range(1000,10000):
raise InvalidCustomerIdException
else:
self._customer_id = int(customer_id)
else:
raise InvalidCustomerIdException
if re.match("^[A-Za-z]+$",last_name):
self._last_name = str(last_name)
else:
raise InvalidNameException
if re.match("^[A-Za-z]+$",first_name):
self._first_name = str(first_name)
else:
raise InvalidNameException
if re.match("^[0-9]{3}\-[0-9]{3}\-[0-9]{4}$",phone_number):
self._phone_number = str(phone_number)
else:
raise InvalidPhoneNumberFormat
def display (self):
return str(self._customer_id) + ", " + self._first_name + self._last_name + "\n" + self._phone_number
