2. 3. 搜索指定key的值 最后,我们可以编写一个函数来实现搜索指定key的值,遍历json数据,找到对应key的值: defsearch_key_value(data,key):ifisinstance(data,dict):fork,vindata.items():ifk==key:print(v)elifisinstance(v,(dict,list)):search_key_value(v,key)elifisinstance(data,list):foritemindata:...
1. 查找key对应的所有值 如果我们希望从案例数据中查找`title`对应的所有值,只需使用下面程序即可 jsondata.search_all_value(key='title') 得到的结果如下: ['Sayings of the Century', 'Sword of Honour', 'Moby Dick', 'The Lord of the Rings'] 2. 查找key对应值的所有路径 如果我们希望从案例数据...
