Python Calculator Code

 

Topic: Calculator using Python.

Hey Guys, today we are going see a Python Program to create a calculator with basic operations like add, subtract, multiply and divide.

Title: Python Code for Calculator with user input. (Beginner Friendly+ Easy + Code + Output + Online Compiler)

What is this program and why we are going to use it?

This Program consists of Variables, Input Function, Conditional Statement, Arithmetic Operator and Comparison Operator.

By using variables, we are going to store values in variables in int or float format according to our use. By using input function, we are going to input values from the user. For example, storing values:
a = 5
b = 6
Here a and b are variables where 5 is assigned to a and 6 is assigned to b.

Now for input function

a = float(input("Enter first number: "))

b = float(input("Enter second number: "))

op = input("Enter operator (+, -, *, /): ")

So, this will ask user to input numbers and operation.

Logic:

1. Take two numbers as input from user.

2. Take an operator (+, -, *, /).

3. Use conditional statements:

   - If operator is '+', add numbers

   - If '-', subtract

   - If '*', multiply

   - If '/', divide (check division by zero)

4. Display the result.

5. If operator is invalid, display an error message.
