是否有强制传递非响应函数的方法

Question

如果这是显而易见的，很抱歉。我以前从未遇到过这种问题。我有一个循环，它调用了一个有问题的函数。99%的情况下，函数会正确返回字符串。另外1%，它什么也不做。它不会引发任何错误，也不会返回任何内容，也不允许我的代码继续到下一行。我曾考虑在一个线程中执行循环，在另一个线程执行计时器，希望终止有循环的线程，但我读到，你必须等待线程完成才能关闭。有人知道在代码挂起时强制终止线程或强制继续到其他行的方法吗？

当我中断代码时，我会从库中挂起的特定行得到一个回调，但我的经验不足，无法自信地进去解决别人的函数。

为了澄清，我正在找一个变通办法。不是我正在调用的函数的修复程序。

我认为这不会有帮助，但以下是有问题的循环

while(True):
start = time.perf_counter()
FEN_board = [["","","","","","","",""],["","","","","","","",""],["","","","","","","",""],["","","","","","","",""],
["","","","","","","",""],["","","","","","","",""],["","","","","","","",""],["","","","","","","",""],]
t1 = threading.Thread(target = find_white_pieces)
t2 = threading.Thread(target = find_black_pieces)
t1.start()
t2.start()
t1.join()
t2.join()
print(create_FEN())
FEN = create_FEN()
FEN = FEN + ' w'
stockfish.set_fen_position(FEN)

move = stockfish.get_best_move() # <---- The function that halts my code completely
print(move)
print(f"Completed in:  {time.perf_counter() - start} seconds")

我不确定我是否理解你的问题。如果它什么都不返回，你的意思是它返回一个Nonetype对象还是一个空字符串。

因为在这种情况下，你只需要做

if func() == np.nan() or func() == '':
continue

如果它抛出错误，你可以进行

try:
func()
except:
continue
