我有一本深度和结构未知的字典。它可能包含更多词典、词典列表等。它是通过反序列化另一个系统创建的一些 JSON 输入而创建的。在该字典的不同位置有一个键，也许是多个具有相同名称的键。我想获取每个键的值并理想地更新它们。
给定这样的目录结构:
{
"tags":{
"social-1":{
"email":True,
"twitter":True,
"facebook":True,
"linkedin":True,
"type":"social"
},
"primary":{
"type":"flexible",
"width":"auto",
"blocks":[
{
"type":"combo",
"data":{
"styles":{
"margin":"10",
"padding":"0",
"borderColor":"#000",
"borderWidth":"0",
"borderStyle":"solid",
"backgroundColor":"transparent",
"width":"auto"
},
"placeholder":True,
"headline":{
"visible":False
},
"subHeadline":{
"visible":False
},
"imageHolder":{
"visible":True,
"value":[
{
"url":None,
"caption":None,
"width":220,
"height":140,
"padding":10,
"alt":"",
"href":None,
"filePath":None,
"sizing":"original",
"source":"disk",
"displayWidth":200,
"displayHeight":140,
"displayPadding":{
"left":10,
"top":0,
"right":10,
"bottom":10
}
}
],
"smartSizing":True,
"captions":False,
"captionDefault":None
},
"content":{
"visible":True,
"value":"<p>Your text here.</p>"
},
"imagePosition":"left",
"textWrap":False,
"type":"combo"
}
},
{
"type":"image",
"data":{
"styles":{
"margin":"10",
"padding":"0",
"borderColor":"#000",
"borderWidth":"0",
"borderStyle":"solid",
"backgroundColor":"transparent",
"width":"auto"
},
"placeholder":False,
"imageHolder":[
{
"url":None,
"caption":None,
"width":0,
"height":140,
"padding":10,
"alt":"",
"href":None,
"filePath":None,
"sizing":"original",
"source":"disk",
"displayWidth":213,
"displayHeight":159,
"displayPadding":{
"left":10,
"top":10,
"right":5,
"bottom":10
}
},
{
"url":None,
"caption":None,
"width":0,
"height":140,
"padding":10,
"alt":"",
"href":None,
"filePath":None,
"displayWidth":213,
"displayHeight":159,
"source":"disk",
"sizing":"original",
"displayPadding":{
"left":5,
"top":10,
"right":5,
"bottom":10
}
},
{
"url":None,
"caption":None,
"width":0,
"height":140,
"padding":10,
"alt":"",
"href":None,
"filePath":None,
"displayWidth":213,
"displayHeight":159,
"source":"disk",
"sizing":"original",
"displayPadding":{
"left":5,
"top":10,
"right":10,
"bottom":10
}
}
],
"orientation":"horizontal",
"smartSizing":True,
"captions":False,
"captionDefault":None,
"type":"image"
}
}
]
}
}
}
我将如何检查和更新 imageHolder 键的值？
请您参考如下方法:
您可以使用递归函数下降到列表和字典值:
def get_all(data, key):
sub_iter = []
if isinstance(data, dict):
if key in data:
yield data[key]
sub_iter = data.itervalues()
if isinstance(data, list):
sub_iter = data
for x in sub_iter:
for y in get_all(x, key):
yield y
