Question

我决定尝试做一个乌龟项目来学习随机命令。我的问题在于此代码：

pos = 360
while a.ycor()<pos:
 a.forward(randint(1,5))
while b.ycor()<pos:
 b.forward(randint(1,5))
while c.ycor()<pos:
 c.forward(randint(1,5))
while d.ycor()<pos:
 d.forward(randint(1,5))
while e.ycor()<pos:
 e.forward(randint(1,5))

如何让所有条件同时执行以开始比赛（所有海龟同时起飞）？

Answer 1

我并非100％确定您要尝试做什么，因此假设您希望同时运行多个功能，请使用multiprocessing或threading模块。快速多处理示例：

import multiprocessing, time

def aFunction(aVar):
    time.sleep(5)
    print(f"Ye {aVar}")

if __name__ == '__main__':
    multiprocessing.freeze_support()

    pool = multiprocessing.Pool(4)
    pool.map(aFunction, [X for X in range(4)])
    input("Press Return to exit")

Answer 2

您可以尝试使用逻辑运算符AND：

pos = 360
while a.ycor()<pos and
      b.ycor()<pos and
      c.ycor()<pos and
      d.ycor()<pos and
      e.ycor()<pos:

     a.forward(randint(1,5))
     b.forward(randint(1,5))
     c.forward(randint(1,5))
     d.forward(randint(1,5))
     e.forward(randint(1,5))

Answer 3

为避免重复，您可以将变量和方法放在字典中，然后循环遍历它们。

pos = 360

d = {a: a.ycor, b: b.ycor, c: c.ycor, d: d.ycor, e: e.ycor}

for k, v in d.items():
    while v() < pos:
        k.forward(randint(1, 5))
