Program:
# Python program to check if a number is prime or not
# input number
num = int(input('Enter a number: '))
count = 0
i = 2
# If number is greater than 1
while(i <= num//2):
if(num % i ==0):
count += 1
break
i += 1
# display result
if(count == 0 and num != 1):
print(num, "is a prime number")
else:
print(num, "is not a prime number")Output:
