A number that is divisible only by itself and 1 (i.e. 2, 3, 5, 7, 11) is called Prime Number.

**Note:** 0 and 1 are not Prime Number

To understand this example, you should have knowledge of following Python programming topics:

## Source Code: Python Program to Check Prime Number

# A number that is divisible only by itself and 1 (i.e. 2, 3, 5, 7, 11) is called Prime Number # 0 and 1 are not Prime Number num = int(input("Enter a number")) if num > 1 : for i in range(2, num): if (num % i == 0 ): print(num," is not a prime number") break else: print(num,"is a prime number") else: print(num," is not a prime number")
