. Python program to check whether the given integer is a prime number or not code example
Example 1: determine if number is prime python
def primeCheck(n):
if n==1 or n==0 or (n % 2 == 0 and n > 2):
return "Not prime"
else:
for i in range(3, int(n**(1/2))+1, 2):
if n%i == 0:
return "Not prime"
return "Prime"
Example 2: how to check if a number is prime in python
import math
def prime(x):
if x == 2 or x == 3 or x==5:
return True
if x == 1 or x == 4:
return False
num = 2
a= math.sqrt(x)+4
while a > num:
if x % num == 0:
return False
else:
num = num + 1
return True
