Check-prime

a number is considered prime if its divisible by one or itself.

#method 1.

define a variable to keep status:

check = False

input number to check if its prime.

num = input("Enter number to check if its prime: ")

prime numbers are greater than 1

if (int(num) > 1):

check for factors

for i in range(2, int(num)):

if factor is found, set check to True

    if (int(num) % i) == 0:
        check = True

break out of loop

        break

check if flag is True

if check: print("The number {}".format(num) + " is not prime") else: print("The number {}".format(num) + " is prime")

method 2

if int(num) > 1:

check for factors

for i in range(2, int(num)):

check for factors

    if (int(num) % i) == 0:
        print("The number {}".format(num) + " is not prime")
    else:
        print("The number {}".format(num) + " is prime")

else:

if number is less than one or equal to one

print("The number {}".format(num) + " is not prime")
