一定时间后迭代next

Question

假设我有以下代码：

possibilities = range(20)
input_name = 4
for i in possibilities:
  exec("import Function_" + str(i))
  exec("Function_" + str(i) + ".solveproblem(" + str(input_name) + ")")

从第二个 exec 函数开始，例如Function_3.solveproblem(4)，可能需要无限时间，我只想尝试（该功能也可能有一些错误）最多1000秒，如果时间超过，我会喜欢停止执行并从另一个 python 文件中执行下一个函数。

有什么想法吗？

你可以试试time的计时器

base = time.time() # Get time before start
for each in possibilities:
    ''do your stuff''
    if time.time()-base>100:
        break # Time limit

或者如果不能滑进去，考虑再开一个线程

def timer:
    base = time.time() # Get time before start
    while True:
        if time.time()-base==100:
            thread.interrupt_main()

            break # Time limit
thread = threading.Thread(target=timer)

thread.start()

now do the rest
