# Definition for a point.

class Solution:

        """

        :rtype: int
        """
        answrs = list()
        for num in range(0, len(points)-2):
            cap = 0
            for point in points:
                cap += 0 if ((point.x - points[num].x)/(points[num+1].x - points[num].x)) - ((point.y - points[num].y)/(points[num+1].y - points[num].y)) else 1
            answrs.append(cap)
        return max(answrs)

Test it yourself. It work for me.
