What are some beginner-friendly Python exercises?

Here are a few beginner-friendly Python exercises you can try:

1. Write a program to print 'Hello, World!'
2. Create a simple calculator that can add, subtract, multiply, and divide.
3. Write a program to check if a number is even or odd.
4. Create a list of your favorite movies and print them out.
5. Write a program that asks for user input and prints it back.

Can you give me a detailed solution for the calculator exercise?

Sure! Here's a simple calculator program in Python:

def calculator():
    print("Select operation:")
    print("1. Add")
    print("2. Subtract")
    print("3. Multiply")
    print("4. Divide")

    choice = input("Enter choice (1/2/3/4): ")

    num1 = float(input("Enter first number: "))
    num2 = float(input("Enter second number: "))

    if choice == '1':
        print(f'The result is: {num1 + num2}')
    elif choice == '2':
        print(f'The result is: {num1 - num2}')
    elif choice == '3':
        print(f'The result is: {num1 * num2}')
    elif choice == '4':
        print(f'The result is: {num1 / num2}')
    else:
        print("Invalid input")

calculator()

This program allows users to select an operation and perform calculations.

What if I want to add more operations?

You can easily add more operations by extending the if statements. For example, to add exponentiation, you can include:

elif choice == '5':
    print(f'The result is: {num1 ** num2}')

Just remember to update the menu options to include the new operation!
