We’ll write Python program to add two numbers. We’ll do it in two ways. First, we’ll find the sum of two numbers without user input i.e. assuming we already have the numbers. Second, we’ll find the sum of two numbers based on the user input i.e. user will provide two numbers to be added.

## Python program to add two numbers

# Python3 program to add two numbers firstNumber = 10 secondNumber = 20 # Calculating sum of two numbers sum = firstNumber + secondNumber # print sum of given two numbers print(f"Sum of {firstNumber} and {secondNumber} is {sum}")

Output

`Sum of 10 and 20 is 30`

## Python program to add two numbers based on user input

# Input two numbers from user # We have assumed the input is int. You can use float if the provided input numbers are of type float firstNumber = int(input('Enter first number: ')) secondNumber = int(input('Enter Second number: ')) # Calculating sum of two numbers sum = firstNumber + secondNumber # print sum of given two numbers print(f"Sum of {firstNumber} and {secondNumber} is {sum}")

Output

```
Enter first number: 10
Enter Second number: 20
Sum of 10 and 20 is 30
```
