我想弄清楚如何在列表中嵌入链接或超链接元素

Question

我试图弄清楚如何将每个玩家的 mlb.com 的链接嵌入到列表中的玩家。 因此，当我点击播放器的名称时，我将被定向到该播放器的 mlb.com 页面。 例如，如果我单击Yordan Alvarez ，它将带我进入他的统计数据，因为它会嵌入到 Yordan Alvarez 中。

这是我到目前为止所尝试的，但我目前被卡住了。 我如何能够将链接嵌入到播放器中，使其像Yordan Alvarez一样工作？

from bs4 import BeautifulSoup
import requests 
import re 

# Request URL 

url_1 = 'https://www.mlb.com/stats/'
req = requests.get(url_1).text
document = BeautifulSoup(req, 'html.parser')

# Body 

tbody = document.tbody

# Headers

thead = document.thead 

# Player Names 

full_name = tbody.find_all('a') 

# List of Players 

players_list = []

for name in full_name: 
    if name.get('aria-label'):
        names = name.get('aria-label')
        players_list.append(names)

# List of Links

hrefs_list = []

hrefs = tbody.find_all('a',href = True) 

# Players & Their Links 

for link,player in zip(hrefs, players_list):
    href_link = link['href']
    if re.search('^/player', href_link):
        stats_link = f'https://www.mlb.com{href_link}'
        hrefs_list.append(stats_link)
        hyperlink_format = f'<a href= {stats_link}>{player}</a>'
print(dict(zip(players_list, hrefs_list)))

Answer 1

您可以使用find_all可以在属性上使用正则表达式的事实。 将其与 dict 理解相结合将其简化为：

from bs4 import BeautifulSoup
import requests 
import re 

base_url = 'https://www.mlb.com'
stats_url = f'{base_url}/stats/'
req = requests.get(stats_url).text
soup = BeautifulSoup(req, 'html.parser')

pattern = re.compile(r"/player/\d+")
links = soup.find_all('a', attrs={'href': pattern})

{a.text: f"{base_url}/{a.attrs.get('href')}" for a in links}

Answer 2

尽量避免应该压缩多个列表，因为它们应该具有相同的长度，而是尝试将您的数据收集在一个 go 中。

您可以使用css selectors到 select 链接/播放器名称，根据预期结果，您可以创建一个dict ：

{a.get('aria-label'): f"{base_url}{a.attrs.get('href')}" for a in soup.select('a[href^="/player/"]')}

或字典列表：

data = []

for a in soup.select('a[href^="/player/"]'):
    data.append({
        'name':a.get('aria-label'),
        'url':f"{base_url}{a.attrs.get('href')}"
    })
data

例子

from bs4 import BeautifulSoup
import requests 

base_url = 'https://www.mlb.com'
req = requests.get(f'{base_url}/stats/').text
soup = BeautifulSoup(req)

data = []

for a in soup.select('a[href^="/player/"]'):
    data.append({
        'name':a.get('aria-label'),
        'url':f"{base_url}{a.attrs.get('href')}"
    })
data

Output

[{'name': 'Yordan Alvarez', 'url': 'https://www.mlb.com/player/670541'},
 {'name': 'Paul Goldschmidt', 'url': 'https://www.mlb.com/player/502671'},

 {'name': 'Aaron Judge', 'url': 'https://www.mlb.com/player/592450'},
