TypeError: can't compare offset-naive and offset-aware times

Question

我有这个功能可以查看一周中的特定时间和日期。它应该从周日 7:00PM 到周五 8:00PM 打印 1 并从星期五 8:00PM 到星期日 7:00PM

打印 0

我在周五 11:00AM 和 2:00PM 左右检查了函数，我在标题中收到了错误消息。

谁能准确解释错误的含义？我怎么可能解决它？它应该总是检查东部标准时间的时间

import pytz
from datetime import datetime, time, date

est = pytz.timezone('EST')

Mon = 0
Tue = 1
Wed = 2
Thur = 3
Fri = 4 
Sat = 5 
Sun = 6

weekdays = [Mon, Tue, Wed, Thur]
edgecases = [Sun, Fri]
weekend = [Sat]

curr_day = datetime.now(tz=est).date().weekday()
curr_time = datetime.now(tz=est).time()

def checktime(curr_day, curr_time):
    if curr_day in weekdays or (curr_day == Sun and curr_time > time(19,00,tzinfo=est)) or (curr_day == Fri and curr_time < time(20,00,tzinfo=est)):
        print(1)

    elif curr_day in weekend or (curr_day == Fri and curr_time >= time(20,00,tzinfo=est)) or (curr_day == Sun and curr_time <= time(19,00,tzinfo=est)):
        print(0)

回溯错误：

Traceback (most recent call last):
  File ".\testingtime.py", line 73, in <module>
    checktime(curr_day, curr_time)
  File ".\testingtime.py", line 67, in checktime
    if curr_day in weekdays or (curr_day == Sun and curr_time > time(19,00,tzinfo=est)) or (curr_day == Fri and curr_time < time(20,00,tzinfo=est)):
TypeError: can't compare offset-naive and offset-aware times

Answer 1

首先，如果您在可识别 tz 的日期时间对象上调用 time() 方法，生成的 time 对象将不再携带时区信息 - 因为假定它没有意义没有日期。其次，由于您与静态时间相比，您在那里不需要时区。因此，您可以将函数简化为

def checktime(curr_day, curr_time):
    if curr_day in weekdays or (curr_day == Sun and curr_time > time(19,00)) or (curr_day == Fri and curr_time < time(20,00)):
        print(1)
    elif curr_day in weekend or (curr_day == Fri and curr_time >= time(20,00)) or (curr_day == Sun and curr_time <= time(19,00)):
        print(0)

Answer 2

这是帮我排序的：

dt_obj = dt_obj.replace(tzinfo=None)
