python: Convert a Counter object to a json object with added key names

Question

I have a Counter object in Python, which contains the following data:

{'a': 4, 'b': 1, 'e': 1}

I'd like to convert this to a JSON object with the following form:

[{'name':'a', 'value': 4} , {'name':'b', 'value': 1}, {'name':'e', 'value': 1}]

Is there any efficient way to do so?

Answer 1

You can use a list comprehension to convert the dictionary to a list of dictionaries. Example -

data = {'a': 4, 'b': 1, 'e': 1}
result = [{'name':key, 'value':value} for key,value in data.items()]

Demo -

>>> data = {'a': 4, 'b': 1, 'e': 1}
>>> result = [{'name':key, 'value':value} for key,value in data.items()]
>>> result
[{'name': 'a', 'value': 4}, {'name': 'b', 'value': 1}, {'name': 'e', 'value': 1}]
