    A calculator program in Python can perform basic arithmetic operations like addition, subtraction, multiplication, and division. Below is an example of a simple command-line calculator.

    # Define functions for operations
    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 x / y
    else:
    return "Error! Division by zero."

    # Display menu
    print("Select operation:")
    print("1. Add")
    print("2. Subtract")
    print("3. Multiply")
    print("4. Divide")

    while True:
    # Take user input
    choice = input("Enter choice (1/2/3/4): ")

    if choice in ('1', '2', '3', '4'):
    try:
    num1 = float(input("Enter first number: "))
    num2 = float(input("Enter second number: "))
    except ValueError:
    print("Invalid input. Please enter numeric values.")
    continue

    if choice == '1':
    print(f"{num1} + {num2} = {add(num1, num2)}")
    elif choice == '2':
    print(f"{num1} - {num2} = {subtract(num1, num2)}")
    elif choice == '3':
    print(f"{num1} * {num2} = {multiply(num1, num2)}")
    elif choice == '4':
    print(f"{num1} / {num2} = {divide(num1, num2)}")

    # Ask for another calculation
    next_calc = input("Do you want to perform another calculation? (yes/no): ")
    if next_calc.lower() != 'yes':
    break
    else:
    print("Invalid choice. Please select a valid option.")
