Question

header = head.find_all('span')

[<span itemprop="name">Raj</span>, <span itemprop="street">24 Omni  Street</span>, <span itemprop="address">Ohio</span>, <span itemprop="Region">US</span>, <span itemprop="postal">40232</span>, <span class="number">334646344</span>]

print(header[0].text)

####output
None
Raj
...

####Expected output
Name
Raj
...

我无法提取 span itemprop 的所有值。它没有输出。我做错了什么吗？

谢谢，拉杰

是的，class 'bs4.element.Tag'没有 tag 属性，因为它本身是一个Tag。来自文档:

You can access a tag’s attributes by treating the tag like a dictionary.

因此，您已经获得了所有 span 标记的列表，现在只需迭代该列表并获取所需的属性(即 'itemprop'):

spans = head.find_all('span')

for span in spans:
    try:
        print(span['itemprop'].decode().title() + ': ' + span.text)
    except KeyError:
        continue 

输出:

Name: Raj
Street: 24 Omni  Street
Address: Ohio
Region: US
Postal: 40232

根据需要格式化输出或存储数据
