該代碼應(yīng)該complex_calculation()在新進程上運行。但是當我執(zhí)行代碼時，一旦單線程完成，它就會重新啟動整個程序，并且我必須再次輸入輸入（這意味著它從代碼的開頭重新啟動，而不是只運行指定的函數(shù)）。我看的教程沒有這個問題。當作者運行時，它不會像我得到的那樣提示輸入兩次。使用 ProcessPoolExecutor 時也存在此問題。Pycharm版本：2020.2 Python版本：3.8這是代碼：import timefrom multiprocessing import Processdef ask_user():    start = time.time()    user_input = input('Enter your name: ')    greet = f'Hello, {user_input}'    print(greet)    print(f'ask_user, {time.time() - start}')def complex_calculation():    start = time.time()    print('Started calculating..')    [x**2 for x in range(20000000)]    print(f'complex_calculation, {time.time() - start}')start = time.time()ask_user()complex_calculation()print(f'Single thread total time: {time.time() - start}')# Start a new process to run complex_calculation functionprocess = Process(target=complex_calculation)process.start()start = time.time()process.join()print(f'Two process total time: {time.time() - start}')
