python - ResultSet 对象没有属性“get”

问题描述

嗨，我目前正在尝试使用 beautifulsoup 抓取此https://www.sec.gov/ix?doc=/Archives/edgar/data/1090727/000109072720000003/form8-kq42019earningsr.htm SEC 链接以获取包含“UPS”的链接"

pressting = soup3.find_all("a", string="UPS")
linkkm = pressting.get('href')
print(linkkm)

但是当我这样做时，我得到了这个错误：

Traceback (most recent call last):
  File "C:\Users\Admin\AppData\Local\Programs\Python\Python36\SEC.py", line 55, in <module>
    print('Price: ' + str(edgar()))
  File "C:\Users\Admin\AppData\Local\Programs\Python\Python36\SEC.py", line 46, in edgar
    linkkm = pressting.get('href')
  File "C:\Users\Admin\AppData\Local\Programs\Python\Python36\lib\site-packages\bs4\element.py", line 2081, in __getattr__
    "ResultSet object has no attribute '%s'. You're probably treating a list of elements like a single element. Did you call find_all() when you meant to call find()?" % key
AttributeError: ResultSet object has no attribute 'get'. You're probably treating a list of elements like a single element. Did you call find_all() when you meant to call find()?

我的预期结果是提取href，然后打印该href。任何帮助，将不胜感激。

解决方案

您的问题是，soup3.find_all() 返回结果列表，并且您尝试在此列表上使用 .get() 方法，而您应该只在一个项目上使用它。

尝试像遍历它们并打印每一个：

pressting = soup3.find_all("a", string="UPS")
for i in pressting:
    print(i.get('href'))
