  1. Best Answer

    也许这些方法会对您有所帮助，re.findall或者re.finditer?
    findall它很容易使用：

    for i in re.findall('<td class="player"><a href="/player/([A-Za-z0-9/]*)"' ,text):
    print(i)

    它会找到你需要的用户：

    13899/la3euka
8368/jmqa
9349/F1L1N
7609/Tresh1k
1866/Shara

    另请注意，它re.findall需要一个 type 变量str，并且您将 html 页面作为一堆字节。

    要获取所有值的集合，您可以先将列表转换为集合，然后再返回列表：

    find = re.findall('<td class="player"><a href="/player/([A-Za-z0-9/]*)"' ,text)
print(list(set(find)))

  2. 另外的选择：

    In [43]: from bs4 import BeautifulSoup

In [44]: soup = BeautifulSoup(html, 'html.parser')

In [46]: links = set(s.find('a').get('href')
                     for s in soup.find_all('td', {'class':['player']}))

In [47]: links
Out[47]:
{'/player/12015/AKIMOV',
 '/player/12016/svyat',
 '/player/13899/la3euka',
 '/player/1866/Shara',
 '/player/7404/insom',
 '/player/7609/Tresh1k',
 '/player/8120/PLAZ',
 '/player/8368/jmqa',
 '/player/9082/krecker',
 '/player/9349/F1L1N'}

  3. 不推荐使用正则表达式解析 html，所以我建议另一种选择，使用BeautifulSoup：

    # Строка или байтовый массив с страницей html
html = ...

from bs4 import BeautifulSoup
root = BeautifulSoup(html, 'lxml')

player_list = set()
for a in root.select('.player > a[href]'):
    player = a['href'].replace('/player/', '')
    player_list.add(player)

# Короткая запись
# player_list = set(a['href'].replace('/player/', '') for a in root.select('.player > a[href]'))

print(player_list)

    安慰：

    {'9349/F1L1N', '7609/Tresh1k', '9082/krecker', '7404/insom', '1866/Shara', '13899/la3euka', '8120/PLAZ', '12015/AKIMOV', '12016/svyat', '8368/jmqa'}
