我正在使用一個 JSON 物件，該物件將每個條目列為 DynamoDB 中的嵌套 JSON 物件。每個條目都有一個作為 JSON 識別符號生成的唯一 ID。我正在嘗試遍歷每個嵌套的 JSON 條目條目并獲取與該條目關聯的所有值（例如“entry.34d6fd1269dd450cbe2437b942d68513.employeeLevel）。不確定如何在不知道條目 ID 的情況下回圈遍歷每個嵌套的 JSON 條目。你會怎么做呢？下面列出了 JSON 物件結構：

"username": "test",

"employeeLevel": "level one",

uj5u.com熱心網友回復：
entry您可以通過以下方式捕獲字典d['entry']（在將json加載到之后d），然后遍歷下的每個鍵entry（假設下的鍵entry是條目ID）并通過以下方式捕獲每個條目ID的字典entry[id]
d = json.loads(s)
entry = d['entry']
for id in entry:
do_something(entry[id])
