Python 映射不同列表中的词典

因此，我这里有以下列表和字典：

{'linked': {'instructors.v1': 
                 [{'id': '3219339', 'fullName': 'Lisa Mazzola'}, 
                  {'id': '6407572',  'fullName': 'Alan S. Miller '}, 
                  {'id': '226710',   'fullName': 'Kevin Werbach'}, 
                  {'id': '8054217',  'fullName': '许 肖潇'}, 
                  {'id': '20696355', 'fullName': 'Варшалович Дмитрий Александрович'},  
                  {'id': '15622422', 'fullName': 'Prof. James Evans'}}], 

'elements': 
    [{ 'id': '69Bku0KoEeWZtA4u62x6lQ', 'name': 'Gamification','instructorIds': '226710'}]

 }

我正试图通过匹配“元素”中与“讲师ID”关联的“讲师.v1”获取“全名”。 我的方法->创建了另一个字典，如下所示：

{'3219339': 'Lisa Mazzola'}
{'6407572': 'Alan S. Miller'}
{'226710': 'Kevin Werbach'}

这给了我一个关键错误：“226710”，即使列表中确实存在226710。请建议另一种方法，否则，我会错在哪里

请向我们展示您所做的尝试，如果您还添加了用于提取数据的代码片段，则编辑将更有帮助。还要注意的是，讲师1.v1是一个字典数组，“226710”是一个值而不是键，键是“id”。@AnisH_GuptA是的。这就是我创建另一个名为“newdict”的字典的原因，我可以使用“226710”作为键，这样我就可以得到名称作为值。你只需要值{3219339'：“Lisa Mazzola”}或者您希望将其分配给元素中的关联id，即{'id'：'tEqImn2kEeWb BLhFdaGww'，指令：[{'3219339'：'Lisa Mazzola'}]}我只需要键的对应值->printInstructorID给出'226710'，然后->instructors=newdict[InstructorID]给出KeyError:'226710'非常感谢。那有帮助！
