Python Project: A Simple Customer Membership Management System

A simple Python-based customer membership management system designed for a fictional e-commerce service called PacCommerce. PacCommerce offers three membership tiers — Platinum, Gold, and Silver — each with its own unique benefits and requirements. This program includes functionality for storing a member database, displaying benefits, checking requirements, automatically predicting membership tiers using Euclidean distance, verifying user identities, calculating price discounts, and providing admin-level access for user management.

Objectives

Learning Objectives

• Demonstrate proficiency in using object-oriented programming (OOP) to create a Python program.
• Apply clean coding practices following PEP8 guidelines.
• Showcase logical and systematic thinking in problem-solving using Python.

Program Features

User Features

• Membership() → Includes an identity verification feature
  Ensures no duplicate user entries and protects data integrity by verifying re-entry of users who were already listed in the database before the program ran.
• show_benefit() → Displays benefit descriptions and discount rates for each membership tier.
• show_requirements() → Displays monthly income and expense requirements for each tier.
• predict_membership() → Automatically assigns a membership tier based on the user's monthly income and expenses using Euclidean distance calculation.
• show_membership() → Displays the user's current membership status.
• calculate_price() → Calculates the total price after applying the appropriate membership-based discount.

Admin Features

• show_all_members() → Displays all registered members (password protected).
• remove_member() → Removes a member from the database (password protected).

Tools Used

• Language: Python 3
• Built-in Modules:
  • tabulate – For clean table display
  • math – Used for Euclidean distance calculation

Program Description

1. paccommerce.py

This Python script implements the core customer membership system for PacCommerce. Both users and admins can access all key features mentioned above through this class-based implementation.

2. test_case_paccommerce.ipynb

This Jupyter Notebook contains structured test cases to validate the paccommerce.py script. It simulates real-world user scenarios and interactions with the membership system, including:

• Viewing membership benefits and requirements
• Predicting the user's membership tier based on income and expenses
• Verifying returning users through identity checks
• Calculating discounted shopping totals
• Admin access to view and remove members securely

How to Run the Program

1. Download both paccommerce.py and test_case_paccommerce.ipynb to your local directory.
2. Open the notebook file (.ipynb) using Jupyter Notebook or VSCode (with the Jupyter extension).
3. Ensure the paccommerce.py script is in the same directory or is properly imported.
4. Run the notebook cells step by step to explore and test all functionalities.
