在Python中执行多线程程序以单线程运行

Question

I've been using threading class alot in my Python codes and have successfully make a couple routine to run as multi-threaded. The problem is when something fails, it becomes a pain when it comes to debugging. This is what my code block would look like:

threads = []
for argument in get_file_method():
    thread = threading.Thread(self._routine, argument)
    thread.start()
    threads.append(thread)

# Wait for all threads to complete
for thread in threads:
    filename = thread.join()

The question is, How can I force the program to run as single threaded in order to ease debug.

Answer 1

There is a dummy_threading module in standard library that you can use instead of threading . It offers the same inteface but runs code sequentially ( start returns when the thread has finished). Of course, your threads must not rely on each other to work in parallel.

import dummy_threading as threading
