calculater in python

            You can create a simple calculator in Python using basic arithmetic operations and functions. Here's an example of a basic text-based calculator:

# Simple Calculator

# Function for addition

def add(x, y):

    return x + y

# Function for subtraction

def subtract(x, y):

    return x - y

# Function for multiplication

def multiply(x, y):

    return x * y

# Function for division

def divide(x, y):

    if y == 0:

        return "Error! Division by zero."

    return x / y

# Main Program

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"{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)}")

else:

    print("Invalid Input")

    

How it works:

• The user selects the operation (addition, subtraction, multiplication, or division).
• The user inputs two numbers.
• The selected operation is performed, and the result is printed.
