1. Basic Calculator

Description:

A simple calculator is one of the most fundamental programs you can build when starting with Python. This project teaches you how to use basic arithmetic operations such as addition, subtraction, multiplication, and division. You will also learn how to create a user-friendly interface using input() and print().

What You’ll Learn:

• Basic arithmetic operations
• Using Python’s input() function to take user inputs
• Conditional statements (if, elif, else)

Example Code:

python
def calculator():
    print("Options:")
    print("Enter 'add' for addition")
    print("Enter 'subtract' for subtraction")
    print("Enter 'multiply' for multiplication")
    print("Enter 'divide' for division")
    print("Enter 'quit' to end the program")
    
    while True:
        user_input = input(": ")

        if user_input == "quit":
            break

        if user_input in ('add', 'subtract', 'multiply', 'divide'):
            num1 = float(input("Enter first number: "))
            num2 = float(input("Enter second number: "))

            if user_input == 'add':
                print(f"Result: {num1 + num2}")
            elif user_input == 'subtract':
                print(f"Result: {num1 - num2}")
            elif user_input == 'multiply':
                print(f"Result: {num1 * num2}")
            elif user_input == 'divide':
                print(f"Result: {num1 / num2}")
        else:
            print("Unknown input")

What You’ll Learn:

• The random module
• Loops (while loop)
• Conditional logic (if, else)

Example Code:

python
import random

def guess_the_number():
    number_to_guess = random.randint(1, 100)
    guess = None
    
    while guess != number_to_guess:
        guess = int(input("Guess a number between 1 and 100: "))

        if guess < number_to_guess:
            print("Too low!")
        elif guess > number_to_guess:

    task = input("Enter a new task: ")
    tasks.append(task)

def remove_task(tasks):
    show_tasks(tasks)
    task_num = int(input("Enter the task number to remove: "))
    tasks.pop(task_num - 1)

def main():
    tasks = []
    while True:
        print("\nOptions: (add, view, remove, quit)")
        option = input("Choose an option: ").lower()
        
        if option == 'add':
            add_task(tasks)
        elif option == 'view':
            show_tasks(tasks)
        elif option == 'remove':
            remove_task(tasks)
        elif option == 'quit':
            break

    if user_choice == computer_choice:
        print(f"Both chose {user_choice}. It's a tie!")
    elif (user_choice == 'rock' and computer_choice == 'scissors') or \
         (user_choice == 'paper' and computer_choice == 'rock') or \
         (user_choice == 'scissors' and computer_choice == 'paper'):
        print(f"You win! {user_choice} beats {computer_choice}")
