为什么我会更早地检查计时器完成 return True，并反复进行？ Tkinter
Why does my check for the timer completion return True earlier, and repeatedly? Tkinter
由于某些原因，在checkTimer()中，if datetime.now() == target_time:在目标时间之前触发，之后重复触发。
我试图修复此问题几个小时但无济于事。这是为什么？

您已通过 checkTimer() 内的行 target_time = datetime.now() 重置了 target_time，因此 datetime.now() == target_time 将被评估为 True。
删除该行。也最好使用 datetime.now() >= target_time 代替：
def checkTimer():
...
#target_time = datetime.now() # remove this line
...
if datetime.now() >= target_time: # used >= instead of ==
...
...
由于某些原因，在checkTimer()中，if datetime.now() == target_time:在目标时间之前触发，之后重复触发。
