Code:

#!/bin/python3

import os
import sys

#
# Complete the pageCount function below.
#
def pageCount(n, p):
    #
    # Write your code here.
    #
     if (p <= n):
        return min(p//2, n//2 - p//2)
    
if __name__ == '__main__':
    fptr = open(os.environ['OUTPUT_PATH'], 'w')

    n = int(input())

    p = int(input())

    result = pageCount(n, p)

    fptr.write(str(result) + '\n')

    fptr.close()

Because you already know which page you want to turn to, that is, the position is already known, so it can be used directly to find the minimum value.
