Python calculator is a program that allows users to perform mathematical operations and calculations using the Python programming language. The code above is a simple example of how you can create a basic calculator in Python. The code takes input from the user, asking for the type of operation they want to perform (addition, subtraction, multiplication, or division) and two numbers. Based on the user’s input, the appropriate function is called and the result is displayed on the screen.

This code is just a basic example and can be expanded upon to add additional functionality, such as handling more complex calculations, supporting decimal numbers, and handling error cases (such as dividing by zero). The beauty of using a programming language like Python is that it provides a wide range of tools and features for building complex applications, so the possibilities are endless.

To create a calculator, you can write a program using a programming language such as Python. Here is an example of how you could create a basic calculator in Python:

# Program to make a simple calculator that can perform four basic arithmetic operations # Function to add two numbers def add(num1, num2): return num1 + num2 # Function to subtract two numbers def subtract(num1, num2): return num1 - num2 # Function to multiply two numbers def multiply(num1, num2): return num1 * num2 # Function to divide two numbers def divide(num1, num2): return num1 / num2 print("Select the operation you want to perform:") print("1. Add") print("2. Subtract") print("3. Multiply") print("4. Divide") # Take input from the user choice = input("Enter your choice (1/2/3/4): ") num1 = float(input("Enter first number: ")) num2 = float(input("Enter second number: ")) if choice == '1': print(num1, "+", num2, "=", add(num1, num2)) elif choice == '2': print(num1, "-", num2, "=", subtract(num1, num2)) elif choice == '3': print(num1, "*", num2, "=", multiply(num1, num2)) elif choice == '4': print(num1, "/", num2, "=", divide(num1, num2)) else: print("Invalid input")
