我想洗掉物件名稱，并將其更改為新的。Withpop()或.delete()。
但無論如何，我得到了同樣的錯誤。
我該怎么辦？
錯誤是：
Traceback (most recent call last):
dataRead ['Teachers'] [3] ['Name']. pop () AttributeError: 'str' object has no attribute 'pop'
uj5u.com熱心網友回復：
你應該做
dataRead['Teachers'][3]['Name'] = "Hello"
uj5u.com熱心網友回復：
dataRead['Teachers'] 是一個串列。一旦您確定了要洗掉的串列中專案的索引（例如，3）然后 dataRead(['Teachers'].pop(3)
uj5u.com熱心網友回復：
您還可以查看 JSONPath 運算式（使用類似 的庫jsonpath-ng）。它使您可以更靈活地瀏覽 JSON 物件。這里有些例子：
更改Name特定元素：
from jsonpath_ng.ext import parser
for match in parser.parse("$.Teachers[?(@.Name=='Mag')]").find(x):
match.value['Name'] = 'New'
Name從具有Name屬性的元素中彈出：
for match in parser.parse("$.Teachers[?(@.Name)].[*]").find(x):
match.value.pop('Name')
Name為所有節點設定Teachers
for match in parser.parse("$.Teachers.[*]").find(x):
match.value['Name'] = 'New name'
