出于某種原因，在 checkTimer() 中，if datetime.now() == target_time:在目標時間之前觸發，之后重復觸發。我試圖解決這個問題幾個小時無濟于事。為什么是這樣？

uj5u.com熱心網友回復：
您已target_time通過target_time = datetime.now()inside行重置checkTimer()，因此datetime.now() == target_time將被評估為 True。
洗掉該行。也更好地使用datetime.now() >= target_time：
def checkTimer():
...
#target_time = datetime.now() # remove this line
...
if datetime.now() >= target_time: # used >= instead of ==
...
...
