如何解决复杂嵌套Json中的Key错误

Question

我不断收到关键错误“注释”。注释位于嵌套响应中。我该如何解决这个问题？我已经包含了 json 的示例。 按请求添加回溯。

    Traceback (most recent call last):
  File "/Users/xxxxxx/Documents/code/trade show w notes", line 16, in <module>

Answer 1

如果您指的是

notes

下的

qualification

键。

那么应该是：

contact["qualification"][0]["notes"]

这里

contact["qualification"]

是一个列表。如果有任何机会 contact["qualification"] 是一个空列表，它将引发

IndexError

。你需要用

try-catch

或

if-clause

来处理它
