台球碰撞-题解(Python代码)

还有，现在用你的代码进行提交，测试全没过……

import math
while True:
    lst = list(map(int, input().strip().split()))
    if max(lst) == 0:
        break
    L, W, x, y, R, a, v, s = tuple(lst)
    vx = v * math.cos(math.pi*a/180)
    vy = v * math.sin(math.pi*a/180)
    for i in range(s):
        x += vx
        y += vy
        if x >= L-R:
            x -= vx
            t = 1-((L-R)-x)/abs(vx)
            vx = -vx
            x = (L-R) + vx*t
        if x <= R:
            x -= vx
            t = 1-(x-R)/abs(vx)
            vx = -vx
            x = R + vx*t
        if y >= W-R:
            y -= vy
            t = 1-((W-R)-y)/abs(vy)
