Question

所以我这里有一个糟糕的小代码

import threading
import time
hours, mins, secs, = 0,0,0


def countUp():
    # so I can get data from get_time
    global hours, mins, secs

    # a game clock thats meant to run in the background
    while True:
        # if mins and secs are 59, add an hour
        if mins == 59 and secs == 59:
            hours += 1
        # if not, don't add anything
        else:
            hours += 0

        # adds a minute when 60 seconds is up (if its 59, it'll print 60 idk why)
        if secs == 59:
            mins += 1
        # after 60 seconds is up, mins would reset to 0 otherwise
        elif mins <= 59:
            mins += 0
        # when mins == 60, reset to 0
        else:
            mins = 0

        # adds a seconds while a minute isn't up
        if secs <= 58:
            secs += 1
        else:
            # resets seconds when a minute is up
            secs = 0

        time.sleep(1)

def get_time():
    # get time from countUp
    global hours, mins, secs
    # print it
    print(f'{hours}:{mins}:{secs} passed')

counter = threading.Thread(target=countUp())
counter.start()

print('This is the base code')
get_time()

它非常磨损，但可以完成工作。如果我运行它，该线程可以运行，但低于 counter.start() 的任何内容都不会运行。我尝试将 while true 循环更改为 for 循环，主程序在函数完成后运行。

我将主程序放在它自己的函数中并对其进行线程化，但没有任何改变。

至于多处理，我不知道我做了什么，但 countUp 似乎没有调用。我做了import multiprocessing并改变了

counter = threading.Thread(target=countUp())
counter.start()

到

if __name__ == '__main__':
    p = multiprocessing.Process(target=countUp, args=())
    p.start()
    p.join()

ps。我知道这段代码很糟糕

python线程没有并行运行
