我推荐使用BeautifulSoup。这里有一些东西可以让你开始：

import requests
from bs4 import BeautifulSoup

url = 'https://www.wikirating.com/list-of-countries-by-credit-rating/'
html = requests.get(url).content
soup = BeautifulSoup(html, 'html.parser')

# Find all tables on the page
tables = soup.find_all('table')

# Loop through each table
for table in tables:
    # Find all rows in the table
    rows = table.find_all('tr')
    # Loop through each row and print the first three elements
    for row in rows:
        cells = row.find_all('td')
        # grabs the first four elements of the row and reads them
        if len(cells) >= 4:
            print(cells[0].text, cells[1].text, cells[2].text, cells[3].text)
