使用线程时如何解决winerror32？

Question

我目前正在使用 python 从互联网上下载一个 mp4 文件，将其转换为 mp3，然后删除该 mp4 文件。我想一次运行这个过程 3，所以我使用了线程。但是，当我访问下载 mp4 的文件夹时，它给了我 winerror32。

我认为这是因为一个线程正在与另一个线程同时访问该文件夹。有没有办法强制线程一次访问一个文件夹？

我尝试使用锁一次只允许一个线程，但它不起作用

def download_multi(music,links,check,parent_file,default_filename,success,fail,total):
    try:
        lock = threading.Lock()
        lock.acquire()
        print(format(threading.currentThread().getName()))
        print("Downloading- ", str(check), "/", total, default_filename + "...")
        check += 1
        lock.release()
        # downloads first audio stream
        music.download(parent_file)
        # creates mp3 filename for downloaded file
        new_filename = default_filename[0:-3] + "mp3"
        print("\nConverting to mp3....")
        # converts mp4 audio to mp3 audio
        lock.acquire()
        audioclip = VideoFileClip(os.path.join(parent_file, default_filename))
        audioclip.audio.write_audiofile(os.path.join(parent_file, new_filename))
        # print("Download finished.")
        # end the video process
        audioclip.close()
        # erase mp4
        if os.path.isfile(parent_file + "\" + default_filename):
            os.remove(parent_file + "\" + default_filename)
            print(default_filename + "delete complete\n")

            # list that would be added to log file
            success.append(default_filename)
        lock.release()
    except Exception as e:
        print(e)
        print("unable to download " + default_filename)
        # list that would be added to log file
        fail.append(default_filename)
        pass

问题是我向方法传递了错误的参数。代码本身没有问题
