Beginner-Friendly Python Projects with Source Code

Introduction

Starting with beginner-friendly Python projects is an excellent way to solidify your understanding of coding fundamentals. As you work on these small projects, you’ll improve essential skills, including working with data types, managing user inputs, using conditionals, and handling basic logic. These projects are designed to be accessible to those new to programming and will help you practice Python concepts in a practical way. Below, we walk through five popular Python projects, complete with step-by-step guides and code examples.

1. Basic Calculator

Why This Project?

A calculator is a foundational project that combines user input, function definitions, and basic arithmetic. It’s perfect for beginners, as it teaches core concepts like function usage and basic error handling (e.g., division by zero). This project also emphasizes reusable code, as each operation (add, subtract, etc.) can be separated into its own function.

Project Description:

This calculator performs basic operations—addition, subtraction, multiplication, and division—based on user input.

Step-by-Step Guide:

  • Define a function for each operation (addition, subtraction, etc.).

  • Create the main function that takes user input for numbers and the type of operation.

  • Handle division by zero using a simple conditional check.

  • Call the appropriate function based on user input.

Source Code:

def add(x, y):
    return x + y

def subtract(x, y):
    return x - y

def multiply(x, y):
    return x * y

def divide(x, y):
    if y == 0:
        return "Error: Division by zero"
    return x / y

def calculator():
    print("Select operation: 1. Add 2. Subtract 3. Multiply 4. Divide")
    choice = input("Enter choice (1/2/3/4): ")
    if choice in ('1', '2', '3', '4'):
        num1 = float(input("Enter first number: "))
        num2 = float(input("Enter second number: "))

        if choice == '1':
            print(f"Result: {add(num1, num2)}")
        elif choice == '2':
            print(f"Result: {subtract(num1, num2)}")
        elif choice == '3':
            print(f"Result: {multiply(num1, num2)}")
        elif choice == '4':
            print(f"Result: {divide(num1, num2)}")
    else:
        print("Invalid input")

2. To-Do List App

Why This Project?

A to-do list application helps you practice data storage, loops, and conditionals. It's also a simple introduction to creating a user interface in the console. By working with lists, you’ll learn how to manage multiple items and use loops to display and manipulate data.

Project Description:

Create a basic to-do list where users can add, view, and delete tasks.

Step-by-Step Guide:

  • Define a list to store tasks.

  • Create functions to add, display, and delete tasks.

  • Use a loop to navigate the menu options and take user inputs for each action.

  • Print the tasks in a numbered list for easy reference.

Source Code:

tasks = []

def add_task():
    task = input("Enter a new task: ")
    tasks.append(task)
    print(f"Task '{task}' added.")

def view_tasks():
    if not tasks:
        print("No tasks available.")
    else:
        for i, task in enumerate(tasks, start=1):
            print(f"{i}. {task}")

def delete_task():
    view_tasks()
    try:
        task_num = int(input("Enter task number to delete: ")) - 1
        removed_task = tasks.pop(task_num)
        print(f"Task '{removed_task}' deleted.")
    except (IndexError, ValueError):
        print("Invalid task number.")

def menu():
    while True:
        print("\n1. Add Task  2. View Tasks  3. Delete Task  4. Exit")
        choice = input("Enter your choice: ")
        if choice == '1':
            add_task()
        elif choice == '2':
            view_tasks()
        elif choice == '3':
            delete_task()
        elif choice == '4':
            print("Exiting To-Do List App.")
            break
        else:
            print("Invalid choice. Please try again.")

3. Number Guessing Game

Why This Project?

The guessing game introduces you to loops, conditionals, and randomness. This project is perfect for understanding the basics of control flow and user interaction. It also teaches you to handle user feedback, which is essential for creating engaging programs.

Project Description:

In this guessing game, the program randomly picks a number, and the player tries to guess it within a range.

Step-by-Step Guide:

  • Use the random module to generate a random number.

  • Create a loop that allows the player to guess multiple times.

Provide feedback if the guess is too high or low.Display the number of attempts once the correct number is guessed.

Source Code:

def add(x, y):
    return x + y

def subtract(x, y):
    return x - y

def multiply(x, y):
    return x * y

def divide(x, y):
    if y == 0:
        return "Error: Division by zero"
    return x / y

def calculator():
    print("Select operation: 1. Add 2. Subtract 3. Multiply 4. Divide")
    choice = input("Enter choice (1/2/3/4): ")
    if choice in ('1', '2', '3', '4'):
        num1 = float(input("Enter first number: "))
        num2 = float(input("Enter second number: "))

        if choice == '1':
            print(f"Result: {add(num1, num2)}")
        elif choice == '2':
            print(f"Result: {subtract(num1, num2)}")
        elif choice == '3':
            print(f"Result: {multiply(num1, num2)}")
        elif choice == '4':
            print(f"Result: {divide(num1, num2)}")
    else:
        print("Invalid input")

Step-by-Step Guide:

  • Use string and random modules to create a pool of characters.

  • Create a function to randomly select characters for a user-defined password length.

  • Output the generated password to the user.

Source Code:

tasks = []

def add_task():
    task = input("Enter a new task: ")
    tasks.append(task)
    print(f"Task '{task}' added.")

def view_tasks():
    if not tasks:
        print("No tasks available.")
    else:
        for i, task in enumerate(tasks, start=1):
            print(f"{i}. {task}")

def delete_task():
    view_tasks()
    try:
        task_num = int(input("Enter task number to delete: ")) - 1
        removed_task = tasks.pop(task_num)
        print(f"Task '{removed_task}' deleted.")
    except (IndexError, ValueError):
        print("Invalid task number.")

def menu():
    while True:
        print("\n1. Add Task  2. View Tasks  3. Delete Task  4. Exit")
        choice = input("Enter your choice: ")
        if choice == '1':
            add_task()
        elif choice == '2':
            view_tasks()
        elif choice == '3':
            delete_task()
        elif choice == '4':
            print("Exiting To-Do List App.")

Why This Project?

This classic game enhances your skills with conditionals and randomness, as well as user input handling. It’s also a great introduction to game logic and writing functions to compare choices and determine the winner.

Project Description:

This version of Rock, Paper, Scissors pits the player against the computer.

Step-by-Step Guide:

  • Create a list of choices (rock, paper, scissors).

  • Use random.choice() for the computer’s move and input() for the player’s choice.

  • Compare choices to determine the winner.

  • Display the result and prompt to play again.

Source Code:

import random

def guessing_game():
    number_to_guess = random.randint(1, 100)
    attempts = 0
    print("Guess the number between 1 and 100.")

    while True:
        guess = int(input("Enter your guess: "))
        attempts += 1
        if guess < number_to_guess:
            print("Too low!")
        elif guess > number_to_guess:
            print("Too high!")
        else:
