使用beautifulSoup错误提取HTML

Question

所以这里的代码是我用来首先提取左上角的时间。

import qgrid
import webbrowser
import requests
from bs4 import BeautifulSoup

page = requests.get('http://www.meteo.gr/cf.cfm?city_id=14') #sending the request to take the html file.
soup = BeautifulSoup(page.content, 'html.parser') #creating beautifulSoup object of the html code.

four_days = soup.find(id="prognoseis")#PINPOINTING to the section that i want to focus (the outer).

#Selecting specific elements , having as my base the seven_day.
periods = [p.get_text() for p in four_days.select(".perhour-rowmargin .innerTableCell-fulltime")]


#creating a Data Frame via pandas to print it TABLE-like.
import pandas as pd
weather = pd.DataFrame({"period ": periods})
print weather

我查了一个很好的教程，开始了解它。 在four_days对象中，我保留了包含在＆＃39; prognoseis＆＃39;中的html代码部分，这就是我想要的信息。 在句点对象之后，我选择包含我想要的信息的元素，并作为第二个参数指定我想要提取的文本。

代码运行并给我空。
