Calculator In Python With Source Code

A Python Program for calculators is a device that performs arithmetic operations on numbers.

The simplest calculators can do only addition, subtraction, multiplication, and division.

More sophisticated calculators can handle exponential operations, roots, logarithms, trigonometric functions, and hyperbolic functions.

Project Details and Technology

About The Project

The Program for Calculator is written in Python programming language, In this article I will teach you How To Make a Calculator In Python.

We may make a simple calculator in Python to execute various arithmetical operations like addition, subtraction, multiplication, and division.

Python has a design philosophy that emphasizes code readability.

That’s why Python is very smooth to use mainly for novices who just started programming. It is very smooth to research the syntax emphasizes clarity and it could reduce time consuming in developing.

A Calculator was designed in GUI or Graphical User Interface using Calculator In Python Tkinter, this article also includes the downloadable Calculator Python Code for free.

How To Make A Calculator In Python?

Complete and Runnable Source Code

This is the runnable source code for the calculator using Python.

# Program make a simple calculator

# This function adds two numbers
def add(x, y):
    return x + y


# This function subtracts two numbers
def subtract(x, y):
    return x - y


# This function multiplies two numbers
def multiply(x, y):
    return x * y


# This function divides two numbers
def divide(x, y):
    return x / y


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

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

    # check if choice is one of the four options
    if choice in ('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))

        # check if user wants another calculation
        # break the while loop if answer is no
        next_calculation = input("Let's do next calculation? (yes/no): ")
        if next_calculation == "no":
            break

    else:
        print("Invalid Input")
