Python Program to Check Whether a Number Is Prime | Prime Number in Python

In this video, we write a Python program to check whether a given number is a prime number or not. This tutorial is a continuation of the previous video, where we discussed what prime numbers are and the logic behind checking if a number is prime. We start by taking an integer input from the user and first verify whether the number is greater than one, since a prime number is a natural number greater than one. Then, we check whether the number has any positive divisors other than one and itself. If such a divisor exists, the number is not a prime number. The program demonstrates two approaches: Checking divisibility from 2 up to the number itself. Optimizing the solution by checking divisibility only up to the square root of the number. We also explain how the for-else loop works in Python and walk through multiple example inputs to clearly understand the program flow. By the end of this video, you will have a complete understanding of how to implement a prime number checking program in Python.
