Write a Python Program to Check Prime Number.

A prime number is a whole number that cannot be evenly divided by any other number except for 1 and itself. For example, 2, 3, 5, 7, 11, and 13 are prime numbers because they cannot be divided by any other positive integer except for 1 and their own value.

Program

def myfun():
    num=int(input("Enter a number: "))
    flag=False
    if(num==1):
        print(num," is not a prime number")
    elif(num>1):
        for i in range(2,num):
            if(num%i==0):
                flag=True
                break
    if flag:
        print(num," is not a prime number")
    else:
        print(num," is a prime number")
if __name__=="__main__":
    myfun()

Enter a number: 28
28 is not a prime number

Enter a number: 13
13 is a prime number
