Write me a code to check if a number is a Pythagorean Prime or not and the other steps required given the following:
Check if a number is a Pythagorean Prime or not | Utility function to check if a number is prime or not.
Corner cases.
This is checked so that we can skip middle five numbers in below loop.
Driver Code.
Check if number is prime and of the form 4 n + 1"
How can the above be solved in Python?

#Here is code to check if a number is a Pythagorean Prime or not and the other steps required.
 def isPrime ( n ) :
	if ( n <= 1 ) :
		return False
	if ( n <= 3 ) :
		return True
	if ( n % 2 == 0 or n % 3 == 0 ) :
		return False
	i = 5
	while ( i * i <= n ) :
		if ( n % i == 0 or n % ( i + 2 ) == 0 ) :
			return False
		i = i + 6
	return True
n = 13
if ( isPrime ( n ) and ( n % 4 == 1 ) ) :
	print ( " YES " )
else :
	print ( " NO " )
