Python function that takes a number as a parameter and check the number is prime or not

prime number:-

A prime number (or a prime) is a natural number greater than 1 and that has no positive divisors other than 1 and itself. 

Python function that takes a number as a parameter and check the number is prime or not

example 1:-

def test_prime(num):
    if (num==1):
        return False
    elif (num==2):
        return True;
    else:
        for x in range(2, num):
            if(num % x==0):
                return False
        return True             
print(test_prime(97))

output:-

True

>>> 

example 2:-

# Python program to check if
# given number is prime or not

num = 11

# If given number is greater than 1
if num > 1:

	# Iterate from 2 to n / 2
	for i in range(2, int(num/2)+1):

		# If num is divisible by any number between
		# 2 and n / 2, it is not prime
		if (num % i) == 0:
			print(num, "is not a prime number")
			break
	else:
		print(num, "is a prime number")

else:
	print(num, "is not a prime number")

output:-

11 is a prime number
