import requests
from bs4 import BeautifulSoup
url = 'https://yandex.ru/pogoda/novosibirsk/details?via=mf#4'
page = requests.get(url)
print(page.status_code)

data_dirt = []
weather_dirt = []
when_dirt = []
soup = BeautifulSoup(page.text,'html.parser')


def today(data_dirt,weather_dirt,when_dirt,soup):
    data_dirt = soup.find_all('span',class_='forecast-details__day-name')
    when_dirt = soup.find_all('div',class_='weather-table__daypart')
    weather_dirt = soup.find_all('div',class_='weather-table__temp')

    data = [item.string for item in data_dirt]
    when = [item.string for item in when_dirt]
    weather = [item.string for item in weather_dirt]

    

    print(data + weather)


today(data_dirt,weather_dirt,when_dirt,soup)
