start_date和end_date是字符串。您应该将它们转换为DateTime对象。这应该是ISO格式，因此您可以使用dateTime.fromisoformat（）
start_date and end_date are strings. You should convert them to a datetime object. This should be the ISO format so you can use datetime.fromisoformat()
问题是
start_time是str类型变量。您必须首先将其转换为datetime对象，然后才能将其使用。要转换，您可以使用此代码库
The problem is
start_timeis astrtype variable. You have to convert it todatetimeobject first, only then you can use timedelta with that.To convert, you can use this codebase
