Python 从类中获取字符串的一部分

HTML是：

<div class="_3u1 _gli _uvb" data-bt='{"id":xxxx,"rank":11,"abtest_version":null,"abtest_params":{"abtest_version":null,"origin":"A","ranker":null},"section":"main_column","owner_id":null,"sub_id":null,"browse_location":null,"query_data":[],"is_headline":false}'>

我得到的回报是：

 {"id":xxxxxx,"rank":1,"abtest_version":null,"abtest_params":{"abtest_version":null,"origin":"A","ranker":null},"section":"main_column","owner_id":null,"sub_id":null,"browse_location":null,"query_data":[],"is_headline":false}

我怎么才能把

xxxxx

退回呢？提前感谢。

您可以解析

数据bt

，因为它包含有效的

json

import json

found =  soup.find_all("div", "_3u1 _gli _uvb")

for fbid in found:
    ...
    bt_json = json.loads(fbid.attrs['data-bt'])
    print(bt_json['id'])
    ...

回答得好！感谢您使用json而不是将其解析为字符串。

import json

found =  soup.find_all("div", "_3u1 _gli _uvb")

for fbid in found:
    ...
    bt_json = json.loads(fbid.attrs['data-bt'])
    print(bt_json['id'])
    ...
