Ich versuche, Daten von einer Wikipedia-Seite zu extrahieren und sie in einen Datenrahmen zu laden. Nach dem Webscraping und Ausführen des Datenrahmens gibt Python einen leeren Datenrahmen zurück, was nicht der Fall sein sollte. Hier ist mein Codeausschnitt:
[code]import pandas as pd
import requests
from bs4 import BeautifulSoup
html = requests.get('https://en.wikipedia.org/wiki/List_of_countries_by_Human_Development_Index')
soup = BeautifulSoup(html.text, 'html.parser')
table = soup.find('table', {'class': 'wikitable'})
rows = table.find_all('tr')[1:]
countries = []
hdi_index = []
for row in rows:
cols = row.find_all('td')
if len(cols) > 2:
countries.append(cols[1].text.strip())
hdi_index.append(cols[2].text.strip())
hdi_df = pd.DataFrame({'Country': countries, 'HDI': hdi_index})
print(hdi_df.head())
