Describe your program here. You must describe your program for a full credit.

$4.$ Design and implement a Python program that asks the user to enter a positive

number and categorizes the number as composite or prime. A composite number

is a number with more than two factors including $1$ and the number itself.

The first prime number is $2$ and the first composite number is $4(10$ pts$).$

Sample input and output

Input:

Enter a positive number: $0$

Output:

$0$ is neither composite nor prime.

Input:

Enter a positive number: $1$

Output:

$1$ is neither composite nor prime.

Input:

Enter a positive number: $2$

Output:

$2$ is a prime number.

Input:

Enter a positive number: $4$

Output:

$4$ is a composite number.

Input:

Enter a positive number: $9$

Output:

$9$ is a composite number.

Input:

Enter a positive number: $-2$

Output:

$-2$ is not a positive integer.

Enter a positive number: a

a is not a positive integer.

Enter a positive number.

Hint: You must include user input validation for the program to pass the test.

Variable: number, is$\_$prime
