I have JSON above and need to parse it with output like this
Logging__LogLevel__Default
Authentication__ApiKeys__0__Claims__0__Type
Everything is ok, but I always get some strings with this output
Authentication__ApiKeys__0__Key
Authentication__ApiKeys__0__OwnerName
Authentication__ApiKeys__0__Claims__0__Type
Authentication__ApiKeys__0__Claims__0__Value
Authentication__ApiKeys__0__Claims__0
Authentication__ApiKeys__2
Authorization__Permissions__Roles__0__Role
Authorization__Permissions__Roles__0__Permissions__1
Authorization__Permissions__Roles__1__Role
Authorization__Permissions__Roles__1__Permissions__0
Authorization__Permissions__Roles__1
Why does my code adds not full strings like
Authentication__ApiKeys__0__Claims__0
Authentication__ApiKeys__2
Authorization__Permissions__Roles__1
And why it doesn't print every value from
Authorization__Permissions__Roles__0__Permissions__*
and from
Authorization__Permissions__Roles__1__Permissions__*
I have this code in python3:
def checkdepth(sub_key, variable):
delmt = '__'
for item in sub_key:
try:
if isinstance(sub_key[item], dict):
sub_variable = variable + delmt + item
checkdepth(sub_key[item], sub_variable)
except TypeError:
continue
if isinstance(sub_key[item], list):
sub_variable = variable + delmt + item
for it in sub_key[item]:
sub_variable = variable + delmt + item + delmt + str(sub_key[item].index(it))
checkdepth(it, sub_variable)
print(sub_variable)
if isinstance(sub_key[item], int) or isinstance(sub_key[item], str):
sub_variable = variable + delmt + item
print (sub_variable)
for key in data:
if type(data[key]) is str:
print(key + '=' +str(data[key]))
else:
variable = key
checkdepth(data[key], variable)
I know that the problem in block where I process list data type, but I don't know where is the problem exactly

Use a recursive generator:
import json
with open('input.json') as f:
data = json.load(f)
def strkeys(data):
if isinstance(data,dict):
for k,v in data.items():
for item in strkeys(v):
yield f'{k}__{item}' if item else k
elif isinstance(data,list):
for i,v in enumerate(data):
for item in strkeys(v):
yield f'{i}__{item}' if item else str(i)
else:
yield None # termination condition, not a list or dict
for s in strkeys(data):
print(s)
Output:

Using json_flatten this can be converted to pandas, but it's not clear if that's what you want. Also, when you do convert it can use df.iloc[0] to see why each column is being provided (ie you see the value for that key).
Note: you need to pass a list so I just wrapped your json above in [].
# https://github.com/amirziai/flatten
dic = your json from above
dic =[dic] # put it in a list
dic_flattened = (flatten(d, '__') for d in dic) # add your delimiter
df = pd.DataFrame(dic_flattened)
df.iloc[0]

Ok, I looked at your code and it's hard to follow. You're variable and function names are not easy to understand their purpose. Which is fine cause everyone has to learn best practice and all the little tips and tricks in python. So hopefully I can help you out.
You have a recursive-ish function. Which is definingly the best way to handle a situation like this. However your code is part recursive and part not. If you go recursive to solve a problem you have to go 100% recursive.
Also the only time you should print in a recursive function is for debugging. Recursive functions should have an object that is passed down the function and gets appended to or altered and then passed back once it gets to the end of the recursion.
When you get a problem like this, think about which data you actually need or care about. In this problem we don't care about the values that are stored in the object, we just care about the keys. So we should write code that doesn't even bother looking at the value of something except to determine its type.
Here is some code I wrote up that should work for what you're wanting to do. But take note that because I did purely a recursive function my code base is small. Also my function uses a list that is passed around and added to and then at the end I return it so that we can use it for whatever we need. If you have questions just comment on this question and I'll answer the best I can.
def convert_to_delimited_keys(obj, parent_key='', delimiter='__', keys_list=None):
if keys_list is None: keys_list = []
if isinstance(obj, dict):
for k in obj:
convert_to_delimited_keys(obj[k], delimiter.join((parent_key, str(k))), delimiter, keys_list)
elif isinstance(obj, list):
for i, _ in enumerate(obj):
convert_to_delimited_keys(obj[i], delimiter.join((parent_key, str(i))), delimiter, keys_list)
else:
# Append to list, but remove the leading delimiter due to string.join
keys_list.append(parent_key[len(delimiter):])
return keys_list
for item in convert_to_delimited_keys(data):
print(item)

Can I get the name of a JSON schema from one of its values using Python?

I am trying to get a JSON sub-schema's "name" from based off of its contents. This is kind of hard to explain, so an example would be better:
{
"dummy_name_1": {
"dummy_key_1": "unique_dummy_value_1",
"dummy_key_2": "dummy_value_2"
},
"dummy_name_2": {
"dummy_key_1": "unique_dummy_value_2",
"dummy_key_2": "dummy_value_2"
}
}
I want to get the name of dummy_name_1 (which would be "dummy_name_1") given the value of the key "dummy_key_1" (which would be "unique_dummy_value_1"). Basically, if I give the Python function I want "dummy_key_1" and "unique_dummy_value_1" as parameters, I want it to return the string "dummy_name_1".

Something like this? structure being your dict.
def get_dummy_name(dummy_key, dummy_value):
for dummy_name, content in structure.items():
if dummy_key in content.keys() and content[dummy_key] == dummy_value:
return dummy_name

try with this:
def get_category_name(key_name, key_value):
dictionary = {
"dummy_name_1": {
"dummy_key_1": "unique_dummy_value_1",
"dummy_key_2": "dummy_value_2"
},
"dummy_name_2": {
"dummy_key_1": "unique_dummy_value_2",
"dummy_key_2": "dummy_value_2"
}
}
for elem in dictionary.items():
if key_name in elem[1] and elem[1][key_name] == key_value:
return elem[0]
return False
response = get_category_name('dummy_key_1', 'unique_dummy_value_1')

Extracting JSON value from key

I have a JSON object like so, and I need to extract the name value of any object, using the id. I have tried many different iterations of this but I can't seem to get anything to work. Any general pointers would be much appreciated. Thank you.
{
"weeks":[
{
"1":[
{
"name":"Stackoverflow Question",
"description":"Have you ever asked a question on StackoverFlow?",
"date":"11/25/2019",
"id":"whewhewhkahfasdjkhgjks"
},
{
"name":"I Can't Believe It's Not Butter!",
"description":"Can you believe it? I sure can't.",
"date":"11/25/2019",
"id":"agfasdgasdgasdgawe"
}

"description":"Sometimes people don't say it be like it is but it do.",
"date":"12/04/2019",
"id":"asdgasdgasdgasd"
}
]
}
]
}

Hope you need to find the name based on id, then try out the code below,
def get_name(data, id):
for week in data['weeks']:
for i in week:
for j in week[i]:
if j['id'] == id:
return j['name']
return None
get_name(data, 'asdgasdgasdgasd')
output
'Testing 123'

Not sure if this is what you are looking for
for week in a["weeks"]:
for k, v in week.values():
print(v['name'])
considering the variable a your dict.

Is the structure fixed, or can the depth of the JSON differ from the example?
This one would work as well if there are more or lesser hierarchies.
It basically searches in each dictionary inside a JSON-like structure for the field_name and returns the value of the argument output_name.
Maybe it helps you when your data structure changes :)

How do I extract a list item from nested json in Python?

I have a json object and I'm trying to extract a couple of values from a nested list. Then print them in markup. I'm getting and error - AttributeError: 'list' object has no attribute 'get'
I understand that it's a list and I can't preform a get. I've been searching for the proper method for a few hours now and I'm running out of steam. I'm able to get the Event, but not Value1 and Value2.
This is the json object
{
"resource": {
"data": {
"event": "qwertyuiop",
"eventVersion": "1.05",
"parameters": {
"name": "sometext",
"othername": [
""
],
"thing": {
"something": {
"blah": "whatever"
},
"abc": "123",
"def": {
"xzy": "value"
}
},
"something": [
"else"
]
},
"whatineed": [{
"value1": "text.i.need",
"value2": "text.i.need.also"
}]
}
}
}
And this is my function
def parse_json(json_data: dict) -> Info:
some_data = json_data.get('resource', {})
specific_data = some_data.get('data', {})
whatineed_data = specific_data.get('whatineed', {})
formatted_json = json.dumps(json_data, indent=2)
description = f'''
h3. Details
*Event:* {some_data.get('event')}
*Value1:* {whatineed_data('value1')}
*Value2:* {whatineed_data('value2')}
'''

From the data structure, whatineed is a list with a single item, which in turn is a dictionary. So, one way to access it would be:
whatineed_list = specific_data.get('whatineed', [])
whatineed_dict = whatineed_list[0]
At this point you can do:
value1 = whatineed_dict.get('value1')
value2 = whatineed_dict.get('value2')

You can change your function to the following:
def parse_json(json_data: dict) -> Info:
some_data = json_data.get('resource')
specific_data = some_data.get('data', {})
whatineed_data = specific_data.get('whatineed', {})
formatted_json = json.dumps(json_data, indent=2)
description = '''
h3. Details
*Event:* {}
*Value1:* {}
*Value2:* {}
'''.format(some_data.get('data').get('event'),whatineed_data[0]['value1'], whatineed_data[0]['value2'])
Since whatineed_data is a list, you need to index the element first

Python handles json as strings unless they are coming directly from a file. This could be the source for some of your problems. Also this article might help.

Assuming that "whatineed" attribute is really a list, and it's elements are dicts, you can't call whatineed.get asking for Value1 or Value2 as if they are attributes, because it is a list and it don't have attributes.
So, you have two options:
If whatineed list has a single element ever, you can access this element directly and than access the element attributes:
element = whatineed[0]
v1 = element.get('value1', {})
v2 = element.get('value2', {})
Or, if whatineed list can have more items, so, you will need to iterate over this list and access those elements:
for element in whatineed:
v1 = element.get('value1', {})
v2 = element.get('value2', {})
## Do something with values

Python remove nested JSON key or combine key with value

I'm receiving json files improperly and am trying to create a temporary fix until the documents come in the proper format. Instead of the value being set to the derivationsValue key, it is being set as a key value pair, so there is an extraneous key. I want to set the the inner value to the outer key.
{
"derivationName": "other_lob_subcd",
"derivationValue": {
"OOP3": "TENANT"
}
}
Given the above json, I want the result to be
{
"derivationName": "other_lob_subcd",
"derivationValue": "TENANT"
}
I could also live with
{
"derivationName": "other_lob_subcd",
"derivationValue": "OOP3-TENANT"
}
or something like that. It just can't be another json element.
Based on #Diana Ayala's answer, I have written this to try solving the problem with variable keys.
for k,v in data['mcsResults']['derivationsOutput']:
if isinstance(k['derivationValue'], dict):
for sk, sv in k['derivationValue']:
k['derivationValue'] = sv

You can use below generic code for your requirement.
import json
filePath = 'file.json'
def getValue(value):
if type(value) is dict:
ans = list(value)[0]
for k in value:
ans += '-'+getValue(value[k])
return ans
return value
def correct(data):
for key in data:
data[key] = getValue(data[key])
return data
if __name__ == "__main__":
with open(filePath) as fp:
data = json.load(fp)
data = correct(data)
print (data)
output:
D:\>python file.py
{'derivationName': 'other_lob_subcd', 'derivationValue': 'OOP3-TENANT'}

For the example given:
import json
with open('inpt.txt') as json_file:
data = json.load(json_file)
data['derivationValue'] = data['derivationValue']['OOP3']
Gives the output:
{'derivationName': 'other_lob_subcd', 'derivationValue': 'TENANT'}
In general, you can look at the solutions here.

You can do something like this:
val = {
"derivationName": "other_lob_subcd",
"derivationValue": {
"OOP3": "TENANT"
}
}
val["derivationValue"] = val["derivationValue"]["OOP3"]
print(val)
This will be the output:
val = {
"derivationName": "other_lob_subcd",
"derivationValue": "TENANT"
}
