Question

我目前有以下代码行

import requests, re, bs4
from urllib.parse import urljoin
start_url = 'http://www.racingaustralia.horse/'

def make_soup(url):
    r = requests.get(url)
    soup = bs4.BeautifulSoup(r.text,"lxml")
    return soup

def get_links(url):
    soup = make_soup(url)
    a_tags = soup.find_all('a', href=re.compile(r"^/FreeFields/"))
    links = [urljoin(start_url,a['href']) for a in a_tags]
return links

def get_tds(link):
    soup = make_soup(link)
    tds = soup.find_all('td', class_="horse")
    for td in tds:
            print(td.text)

if __name__ == '__main__':
    links = get_links(start_url)
    for link in links:
        get_tds(link)

这会使来自racingaustralia.com/horse

的桌面会议的所有马名称全部删除

这正是我想要的，但我也想要检索会议日期，会议地点和每场比赛，列出马名。

这是我想要的一个例子：

Date of Race Meet
Location of Race Meet
Race Number
Horse....
...
...
...
Race Number
Horse
...
...
etc

是否有人能够帮我调整代码，以便打印每场比赛的日期和地点以及每匹马的比赛号码？

我尝试了以下方法，但我想知道是否有更有效的方法。

def get_tds(link):
    soup = make_soup(link)
    race_date = soup.find_all('span', class_="race-venue-date")
    for span in race_date:
        print(span.text)

    tds = soup.find_all('td', class_="horse")
    for td in tds:
        print(td.text)

def get_info(link):
    item = soup.find_all('div', class_="top")
    for div in item:
        print(div.text)

if __name__ == '__main__':
    links = get_links(start_url)
    for link in links:
        get_info(link), get_tds(link)

提前致谢
