Creating a Calculator in Python

Python is a great language for creating a basic calculator. With a few lines of code, you can create a fully functional calculator. In this tutorial, we will go through the steps of creating a basic calculator in Python.

First, we will create a function that will take two numbers as arguments and return the result of the sum of the two numbers. The function will look like this:

def add(x, y):
  return x + y

This function takes two arguments, x and y, and returns the sum of the two numbers. We can use this function to create a calculator that will add two numbers.

We will create a while loop that will take two numbers from the user, call the add() function, and print out the result. The code will look like this:

while True:
  x = int(input("Enter the first number: "))
  y = int(input("Enter the second number: "))
  print("The sum is: ", add(x, y))

This code will run an infinite loop that will prompt the user to enter two numbers and then print out the result of the sum of the two numbers. We can also use this loop to create a calculator that will subtract two numbers by changing the function to the following:

def subtract(x, y):
  return x - y

Now, the calculator will subtract the two numbers instead of adding them. We can also use this loop to create a calculator that will multiply two numbers by changing the function to the following:

def multiply(x, y):
  return x * y

Now, the calculator will multiply the two numbers instead of subtracting them. Finally, we can use this loop to create a calculator that will divide two numbers by changing the function to the following:

def divide(x, y):
  return x / y

Now, the calculator will divide the two numbers instead of multiplying them. This is how you can create a basic calculator in Python using a while loop and a few lines of code.
