  Problem Description: Building a Digital Shopping Cart
  
  Imagine you're tasked with developing a digital shopping cart system for an online store. Your goal is to implement a Python program that allows users to add items to their cart, view the cart contents, calculate the total cost, and complete the purchase. This assignment will test your proficiency in Python, particularly in handling classes and objects.
  
  Your Mission: Implementing the Shopping Cart Program
  
  1. Object-Oriented Design
  - Create a class for the shopping cart.
  - Implement methods for adding items, viewing the cart, and calculating the total cost.
  
  2. User Interaction
  - Develop a simple user interface for interacting with the shopping cart.
  - Allow users to add items, view the cart, and complete the purchase.
  
  3. Data Handling
  - Explore techniques for storing and managing item information.
  - Consider using dictionaries or other data structures to organize and retrieve item details.
  
  4. Error Handling and Validation
  - Implement robust error handling.
  - Ensure the program gracefully handles scenarios such as invalid item entries or attempts to purchase an empty cart.
  
  How to Approach the Problem: Strategic Steps
  
  Step 1: Object-Oriented Design
  - Design a class structure for the shopping cart.
  - Define methods for adding items, viewing the cart, and calculating costs.
  
  Step 2: User Interaction
  - Develop a simple interface for users to interact with the shopping cart.
  - Implement functionality for adding items, viewing the cart, and completing a purchase.
  
  Step 3: Data Handling
  - Explore different ways to store and manage item information within the program.
  - Consider the pros and cons of various data structures.
  
  Step 4: Error Handling and Validation
  - Implement error handling to ensure a smooth user experience.
  - Consider edge cases and potential issues users might encounter.
  
  Example: Exploring the Shopping Cart
  
  Let's walk through a sample scenario to solidify your understanding. The provided Python solution is a guide for your implementation, allowing you to adapt the logic to your programming style.
  
  Input:
  
  ```python
  # User adds items to the cart
  cart = ShoppingCart()
  cart.add_item("Laptop", 1200)
  cart.add_item("Headphones", 150)
  cart.add_item("Mouse", 30)
  
  # User views the cart
  cart.view_cart()
  
  # User completes the purchase
  cart.purchase()
  ```
  
  Output:
  
  ```python
  Cart Contents:
  1. Laptop - $1200
  2. Headphones - $150
  3. Mouse - $30
  
  Total Cost: $1380
  
  Purchase successful!
  ```
  
  Conclusion: Elevating Python Proficiency
  
  This assignment not only challenges your Python programming skills but also provides a practical application of object-oriented design. By crafting a digital shopping cart, you'll deepen your understanding of Python's capabilities and enhance your ability to solve real-world programming problems.
