### CHALLENGE:

A prime number is a number that is only evenly divisble by itself and 1.

For example, the number 5 is prime because it can only be evenlly divided by 1

and 5. The number 6, however, is not prime because it can be divided evenly

by 2 and 3.

and returns true if the argument is a prime number, or false otherwise. Use

the function in a program that prompts the user to enter a number and then

prints whether the number is prime.

### SOLUTION:

n=int(input("Enter an integer:")) def is_prime(n): if n<2: return False elif n==2: return True else: i=2 while i<n: if((n%i)==0): return False elif (n==27): return False else: i+=1 return True print(is_prime(n))
