Example: Payment Program

Scenario:

We have two Python modules:

1. orders.py – Handles order creation.

2. payments.py – Processes payments.

When an order is placed, it sends the order details to the payment module for processing.

Step 1: Define the payments Module

payments.py

def process_payment(order_id, amount):
    print(f"Processing payment of ${amount} for Order {order_id}")
    return f"Payment for Order {order_id} successful"

Step 2: Integrate with the orders Module

orders.py

from payments import * #Import the payments module

def place_order():
    order_id = 101
    amount = 50.00
    confirmation = payments.process_payment(order_id, amount)  #Integration happens here
    print(confirmation)

place_order() #Run the function to simulate order placement

Expected Output:

Processing payment of $50.0 for Order 101
Payment for Order 101 successful
