使代码行在特定时间运行python3

Question

我正在用Python为我的老师编写一个代码，我需要帮助使代码在指定的时间运行。现在，我只是想让代码在实现程序的简单功能之前运行。。。你知道吗

我希望代码在每次上课时运行。我做不到。下面是基本代码。你知道吗

import datetime
from datetime import date
import calendar

while True:
    my_date = date.today()
    day=calendar.day_name[my_date.weekday()]
    time_now = datetime.datetime.now()

    if day == 'Monday':
        if time_now.hour >= 9 and time_now.minute >= 10:
            if time_now.hour >= 10 and time_now.minute >= 30:
                if time_now.hour >= 11 and time_now.minute >= 30:
                    if time_now.hour >= 13 and time_now.minute >= 10:
                        if time_now.hour >= 14 and time_now.minute >= 5:
                            #period 5
                        else:
                            #period 4
                    else:
                        #period 3
                else:
                    #period 2
            else:
                #period 1

        else:
            continue
            #not in range

下面是我目前的代码，我很满意-相反，我想用一个自动类选择器替换下拉菜单。我建议你运行这个，这样你就能明白我的意思。你知道吗
