Question

请查看我的代码。
运行此代码将导致递归错误请告诉我是否有一种有效的写作方式，不会导致递归错误此外，sys.setrecursionlimit（10000）导致崩溃。

def on_touch_move(self, touch):
    if touch.y > self.touch_pos_y:
        if self.anim_search_direction == 'up':
            self.anim_search_direction = 'down'
            anim_s_h_u_1 = Animation(opacity=0, duration=.6, t='out_expo')
            anim_s_h_u_2 = Animation(height=sp(40), duration=.6, t='out_expo')
            anim_s_h_u_3 = Animation(height=sp(40), duration=.6, t='out_expo')
            anim_s_h_u_4 = Animation(height=sp(40), duration=.6, t='out_expo')
            anim_s_h_u_1.start(self.a)
            anim_s_h_u_2.start(self.b)
            anim_s_h_u_3.start(self.c)
            anim_s_h_u_4.start(self.d)
    elif touch.y < self.touch_pos_y:
        if self.anim_search_direction == 'down':
            self.anim_search_direction = 'up'
            anim_s_h_u_1 = Animation(opacity=1, duration=.6, t='out_expo')
            anim_s_h_u_2 = Animation(height=sp(66), duration=.6, t='out_expo')
            anim_s_h_u_3 = Animation(height=sp(80), duration=.6, t='out_expo')
            anim_s_h_u_4 = Animation(height=sp(66), duration=.6, t='out_expo')
            anim_s_h_u_1.start(self.a)
            anim_s_h_u_2.start(self.b)
            anim_s_h_u_3.start(self.c)
            anim_s_h_u_4.start(self.d)

TRACEBAK就在这里并循环使用。

Python kivy超出了最大递归深度
