Write a Python Program to Check Prime Number

A prime number is a natural number greater than 1 that is not a product of two smaller natural numbers. In other words we can say that a prime number is a natural number greater than 1 which are divided by 1 and itself. Smallest prime number is 2 (2 is the only even prime number).

For example

11 is a prime number as it is divided by 1 and itself.

23 is a prime number as it has only two factors (1 and 23.)

25 is not a prime number as it has more than 2 factors(1, 5 and 25)

### Explanation of above code

1. Accept any number (say n1) from the user.
2. If the number is greater than one(1), then we will check that whether this number is divisible by any other number between 2 and half of that number(n1) with the help of ‘for’ loop.
3. If the above condition is true then we will display “It is a Prime number” otherwise we will display “It is not a prime number”
4. If the number is less than one(1) then it is not a prime number.
