Question

我具有以下要素：<a class="text-name username ng-binding" ng-href="https://www.roblox.com/users/18734213/profile" ng-bind="resaleRecord.seller.name" href="https://www.roblox.com/users/18734213/profile">RobotronicDude</a>

im尝试使用漂亮的汤打印第一个ng-href 但它说：

Traceback (most recent call last):
  File "C:\Users\Maxva\Desktop\Python Projects\LimSniepr\LimSniper.py", line 24, in <module>
    ta = soup.findAll('a', {'class': 'text-name username ng-binding'})[0]['ng-href']
IndexError: list index out of range

我尝试过的代码：

id = input("Enter a id to snipe: ")

url = f'https://www.roblox.com/catalog/{id}/'
soup = BeautifulSoup(requests.get(url).content, 'html.parser')

ta = soup.findAll('a', {'class': 'text-name username ng-binding'})[0]['ng-href']
print(ta)```

您应该检查为什么打印解析后得到的列表会发生这种情况。以下代码可以正常工作：

from bs4 import BeautifulSoup

s = """\
<a class="text-name username ng-binding" ng-href="https://www.roblox.com/users/18734213/profile" ng-bind="resaleRecord.seller.name" href="https://www.roblox.com/users/18734213/profile">RobotronicDude</a>
"""

soup = BeautifulSoup(s, features="lxml")

for item in soup.find_all('a', {'class': 'text-name username ng-binding'}):
    print(item['ng-href'])

还有可能是您的网址不正确，所以我强烈建议使用soup.prettify进行检查
