Write a Boolean function named is_prime which takes an integer as an argument 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.

LANGUAGE:  PYTHON

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.

Write a Boolean function named is_prime which takes an integer as an argument
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))
