Customer Class

'''
Class called Customer
Every customer has a name,
number, email, phone and they
can collect rewards points
An object is collection of related
functions. They all relate
to one topic like customer.
The idea is to make it easier
to manage complex code
by breaking it into the kinds
of objects that actually make up
the contents of the program
abstraction
encapsulation
inheritance
polymorphism
'''
class Customer():
    def __init__(self, number, name, phone, email, rewards):
        self.number=number
        self.name=name
        self.phone=phone
        self.email=email
        self.rewards=rewards

It will represent an item to purchase
It will have a number, a name and a price
'''
