我有数据框，其中一列是一个字典列表，存储为字符串，如下所示：
name age misc
Jim 44 "[{"value":3,"type":"cars"},{"value":1,"type":"pets"},{"value":13,"type":"shoes"}]"
Bob 25 "[{"value":3,"type":"siblings"},{"value":1,"type":"pets"}]"
Sue 55 "[]"
我想谈谈这个问题，每个类型都有自己的列，并带有相应的值：
name age cars pets shoes siblings
Jim 44 3 1 13 0
Bob 25 0 1 0 3
Sue 55 0 0 0 0
