Write a Python program to print the sum of two numbers.

In mathematics, summation is the addition of a sequence of numbers; the result is their sum or total. The numbers to be summed may be integers, rational numbers, real numbers, or complex numbers.

Program 1: Add two numbers in python

With the assignment operators added, this code will correctly calculate the sum of the two variables “num1” and “num2” and print the result to the console.

Here’s a brief explanation of how the code works:

1. “num1” and “num2” are defined and given values. “num1” is an integer and “num2” is a float.
2. The sum of the two variables is calculated by first casting “num1” to a float and then adding it to “num2”. This ensures that the result of the calculation is a float.
3. The sum is printed to the console using string formatting. The “{0}, {1}, {2}” placeholders are replaced with the values of “num1”, “num2”, and “sum”, respectively.

Program 2: Add two numbers entered by user in Python

This code prompts the user to enter two numbers and then calculates the sum of the two numbers. The sum is printed to the console.

Here’s a brief explanation of how the code works:

1. The “num1” and “num2” variables are assigned the values entered by the user.
2. The sum of the two variables is calculated by casting them to floats and adding them together.
3. The sum is printed to the console using string formatting. The “{0}” placeholder is replaced with the value of “sum”.
