## What is a Composite Number?

A composite number is a positive integer number that is not prime number. In other words, it is a positive integer number which has at least one divisor other than 1 and itself. The composite numbers up to 20 are 4, 6, 8, 9, 10, 12, 14, 15, 16, 18, 20.

For example:

Input: 10

Output: yes, its Composite (Because 10 has divisors other than 1 and itself, for ex, 2 or 5).

Input: 5

Output: no, its not Composite (Because 5 is a prime number, as it has no other divisors other than 1 and itself).

**Problem Statement:**

### Write a program to check if the user input is a composite number or not in Python

#### Code:

def composite(n):
if n <=1:
return("Number less than or equal to 1!")
else:
for x in range(2,n):
if n%x==0:
return("composite")
return("Non composite, it's a prime number")
try:
n=int(input())
print("Input:",n)
print(composite(n))
except:
print("Error!!")
