Can you provide a code to count alphanumeric palindromes of length N and the other steps required given the following:
Count alphanumeric palindromes of length N | Function to calculate ( x ^ y ) mod p.
Initialize result.
Update x if it is more than or equal to p.
If y is odd , multiply x with result.
y must be even now.
Return the final result.
Given N.
Base Case.
Check whether n is even or odd.
Function Call.

How can the above be solved in Python?

#Here is code to count alphanumeric palindromes of length N and the other steps required.
 def power ( x , y , p ) :
	res = 1
	x = x % p
	if ( x == 0 ) :
		return 0
	while ( y > 0 ) :
		if ( ( y & 1 ) == 1 ) :
			res = ( res * x ) % p
		y = y >> 1
		x = ( x * x ) % p
	return res

if ( ( N == 1 ) or ( N == 2 ) ) :
	print ( 62 )
else :
	m = ( 10 ** 9 ) + 7
	if ( N % 2 == 0 ) :
		k = N // 2
		flag = True
	else :
		k = ( N - 1 ) // 2
		flag = False
	if ( flag ) :
		a = power ( 62 , k , m )
		print ( a )
	else :
		a = power ( 62 , ( k + 1 ) , m )
		print ( a )
