Question

我想设置时间以灵活的时间通知用户，我想我想input。我可以在特定时间获得期望的输出，但是当我输入期望的时间时，它不会通过程序。再次要求input时间：我需要打印时间并通知并继续执行程序：

20:24:00
  >

>>> from win10toast import ToastNotifier
>>> import time
>>> def run_app():
>>> show_help()
>>> while True:
>>>     #set time to notify for shopping
>>>     notification_time = time.strftime("%H:%M:%S")
>>>     if notification_time == input("Please enter a specific time:\n"):
>>>         print(notification_time)
>>>            
>>>         break
>>>     else:
>>>         pass
>>> #organise the notification
>>> notification1= ToastNotifier()
>>> notification1.show_toast("Alarm","It is time to shop ")

现在的结果是：

Please enter a specific time:
20:24:00
Please enter a specific time:
...

Answer 1

您的输入回路逻辑错误。它与您要说的完全不符：

notification_time = time.strftime("%H:%M:%S")
# This stores the current time, mis-named "notification_time"

if notification_time == input("Please enter a specific time:\n"):
# This requires the user to enter a time in the required format.
# If that doesn't match the current time at the previous instruction,
#   you ignore the input and repeat the process.

最后，如果用户确实设法在当前时间输入当前时间，则将其作为通知时间。用户无法输入将来的时间。

相反，您需要接受用户的通知时间，然后检查该格式的有效性。最简单的方法通常是接受输入字符串，然后使用try/except块将其转换为时间。如果失败，则循环返回以再次尝试输入。

我试图将您的想法变成功能代码：

    from datetime import datetime
    import time
    from win10toast import ToastNotifier
    toaster = ToastNotifier()
    # Validate if the format of the time that the user submitted is correct
    def isTimeCorrect(input):
        try:
            time.strptime(input, '%H:%M:%S')
            return True
        except ValueError:
            return print('time is wrong')
    # Request the user to type the alarm time
    alarm = input('Type your alarm time in this format HH:MM:SS\n')
    # Get the current time
    now = datetime.now()
    # Format the current time
    current_time = now.strftime("%H:%M:%S")

    # Loop and check the current time until it's the same as the alarm
    while (isTimeCorrect(alarm)):
        now = datetime.now()
        current_time = now.strftime("%H:%M:%S")
        # Check if the current time is the same as the alarm
        if current_time == alarm:
            # throw the notification
            toaster.show_toast("Example","Notifcation Text",icon_path=None,duration=5,threaded=True)
            break

有什么方法可以设置通知时间？
