A prime number is an integer that is greater than 1 and that is only evenly divisible by itself and 1. For example, the number 5 is prime because it can only be evenly divided by 1 and 5. The number 6, however, is not prime because it can be divided evenly by 1, 2, 3, and 6. Write a function name isPrime, which takes an integer as an argument and returns true if the argument is a prime number, or false otherwise. Demonstrate the function in a complete program that prompts for a number and indicates whether or not it is prime.

def Isprime(number):

          if number>1 :

                  for i in range(2, number):

                          if (number % i) == 0:

                                   print(number, "is not a prime number")

                                   break

                    else:

                              print (number, "is a prime number")

           else:

                   print(number, "is not a prime number")

x = Isprime(5)

y = Isprime(17)

z = Isprime(14)

Explanation:

A prime number is a number that can only be divided by 1 and itself. Prime number includes 5, 7, 11 etc.

def Isprime(number):  A function is created Isprime and the argument number is used.

if number>1 :  if the number is greater than 1 .

for i in range(2, number):  This expression loop through 2 to the number(argument)

if (number % i) == 0:  If the number divided by the looped value is equal to zero.

print(number, "is not a prime number")   print the number is not a prime number

break   This means stop and go back to the loop

else:   otherwise

print (number, "is a prime number") Print the number is a prime number.

else: This else is under the first if statement.

print(number, "is not a prime number")  print the number is not a prime number.

x = Isprime(5)

y = Isprime(17)

z = Isprime(14)

These call the function with the argument.
