Hey I'm trying to rotate a rectangle around its center and when I try to rotate the rectangle, it moves up and to the left at the same time. Does anyone have any ideas on how to fix this?

def rotatePoint(self, angle, point, origin):
    sinT = sin(radians(angle))
    cosT = cos(radians(angle))
    return (origin[0] + (cosT * (point[0] - origin[0]) - sinT * (point[1] - origin[1])),
                  origin[1] + (sinT * (point[0] - origin[0]) + cosT * (point[1] - origin[1])))

def rotateRect(self, degrees):
    center = (self.collideRect.centerx, self.collideRect.centery)
    self.collideRect.topleft = self.rotatePoint(degrees, self.collideRect.topleft, center)
    self.collideRect.topright = self.rotatePoint(degrees, self.collideRect.topright, center)
    self.collideRect.bottomleft = self.rotatePoint(degrees, self.collideRect.bottomleft, center)
    self.collideRect.bottomright = self.rotatePoint(degrees, self.collideRect.bottomright, center)
