您的代碼引發此異常：

AttributeError: type object 'Meeting' has no attribute 'datetime'

在這一行：

meeting_start = Meeting.datetime.start_time.hour

Python告訴您，Meeting類沒有名為datetime的屬性。這是真的：Meeting類是一個制造meeting對象的工廠(或實例)，這些對象有start_time和end_time屬性，可以這樣訪問：>>> meeting = Meeting(datetime(2018, 8, 1, 9, 0, 0), datetime(2018, 8, 1, 11,

0, 0))

>>> print(meeting.start_time)

2018-08-01 09:00:00

>>> print(meeting.end_time)

2018-08-01 11:00:00

正在向您的check_availability函數傳遞一個會議列表，因此您需要循環查看該列表，以檢查是否有任何會議與建議的會議時間沖突。def check_availability(meetings, proposed_time):

# Loop over the list of meetings; "meeting"

# is the meeting that you are currently inspecting.

for meeting in meetings:

# if proposed_time is between meeting.start_time

# and meeting.end_time, return False

# If you get through the list without returning False

# then the proposed time must be ok, so return True.
