我有一個json文件，我需要列出所有數據的所有“自文本”元素。任何例子？數據示例{ "data": [ { "selftext": "hello there", "textex": true, },

如果您希望能夠在任意級別從任意 json 中找到密鑰，則應使用遞歸：
def findkey(data, key, resul = None):
if resul is None: resul=[] # initialize an empty list for the results
if isinstance(data, list): # walk down into lists
for d in data:
findkey(d, key, resul)
elif isinstance(data, dict): # dict processing
for k,v in data.items():
if (k == key) and isinstance(v, str): # the expected key and a string value?
resul.append(v)
elif isinstance(v, list) or isinstance(v, dict):
findkey(v, key, resul) # recurse if value is a list or a dict
return resul
例：
>>> data = { "data": [
{
"selftext": "hello there",
"textex": True,
},
]}
>>> findkey(data, 'selftext')
['hello there']
