How get schedule with io with aiogram in pycharm

Question

I'm working on Get Schedule bot in telegram, I want that when the user selects the set schedule("установить расписание") function, the schedule of his classes automatically comes to him every morning at a given time, taking into account his group, of course. I used from io import StringIO to get the date and the site where the schedule is posted, but I can't bring it to mind so that the user can use it

like, Comtehno>>установить расписание(set schedule)>>ДПО-3-23 (for e.g)>> telegram bot send message "Great! Now you'll get your schedule of your group class

I wanted make as side things I would like to do the back buttons using FSM, but I haven't figured that out either :<

from io import StringIO
from aiogram import Bot, Dispatcher, executor, types
from aiogram.types import ReplyKeyboardMarkup, ReplyKeyboardRemove, KeyboardButton
from aiogram.types import InlineKeyboardButton, InlineKeyboardMarkup
from bs4 import BeautifulSoup

page = requests.get(url)

soup = BeautifulSoup(page.text, 'lxml')

tmp = (pd.read_html(StringIO(page.text))[0].iloc[4:, 1:]
       .dropna(how="all").T.set_index(4).T)

s = tmp.columns.to_series()
tmp.columns = (s.str.cat(s.groupby(level=0).cumcount().add(1)
                         .astype(str), sep="-").where(s.duplicated(keep=False), s))

df = tmp.set_index(["Время-1", "Время-2"]).rename_axis(columns=None)

print(df.loc["ПОНЕДЕЛЬНИК", "ДПО-3-23"])
