from datetime import datetime, date, time
import urllib.request
from bs4 import BeautifulSoup
def site(url):
    response = urllib.request.urlopen(url)
    return response.read()
 
def parse(html):
    soup = BeautifulSoup (html)
    data = soup.find('div', class_='wrap wrap__name_main-content')
    dataa = data.find_all('h1', class_='page-title')
    dataaa = dataa[0].text.strip()
    soup.body.decompose()
    print(dataaa)
 
def main():
    parse(site(' https://www.sgu.ru/schedule/mm/do/242' ))
