# Question 4:
# Write a Customer class and Items class. Let user enter customer information and add stuff to his/her shopping card.
# Class Items :
# Method : __init__(), __str__(), calculate_discount(), shopping_cart(), get_total_amount()
# calculate_discount():
# total_price = price * qty
# discount —> 25% if total_price >= 4000
# discount —> 15% if total_price >= 2000
# discount —> 10% if total_price < 2000
# price_tobe_paid = total_price – discount
# shopping_cart():
# Let user add items in the shopping basket. Be creative with the items, set their prices as well.
# __str__():
# Print items added and total price nicely.
# Class Customer :
# Methods: __init__(), get_cust_info() this is optional, __str__()
# Optionally create a get_cust_info() or similar to allow customer to enter his/her information or
# just define them in __init__() and pass customer information as arguments while creating a customer object.
# __str__():
# Print customer information and price nicely.
# Find a way to link two classes. For example, instances of both classes may have a customer number.
# With a get method, get the customer number and pass it to the item object as an argument to set customer number attribute.
# So Customer class instance holds the customer info, Items class holds the shopped item’s info for the same customer
# ID number such as price, quantity or so.
# In the end, print both info (customer info and shopped items info) using their respective __str__ format in a nice way.
# Simple example:
# Customer1 = [name : Jack, last_name : Russel, customer_id : 123]
# shopping_cart1 = [customer_id : 123, items : [necklace, ring, ear ring], total_price : 2000, discount : 300, price_tobe_paid : 1700]
# Crate a few customers and print their information (Personal and shopping info).
