Python：运行进度栏并同时工作？

你可以在运行使用后台线程的

threading

def run_progress_bar(finished_event):    chars = itertools.cycle(r'-|/')    while not finished_event.is_set():        sys.stdout.write('rWorking ' + next(chars))        sys.stdout.flush()        finished_event.wait(0.2)# somewhere else...finished_event = threading.Event()progress_bar_thread = threading.Thread(target=run_progress_bar, args=(finished_event,))progress_bar_thread.start()# do stufffinished_event.set()progress_bar_thread.join()
