Load a dict-like string which includes None value using python

Question

Assume there is a string like '{"a": None}'. How to let Python know the existence of None?

This is the error I have been receiving:

JSONDecodeError: Expecting value: line 1 column 7 (char 6)

If you are trying to decode a JSON, which is implied by your error, you should use `null` instead of `None`. — mati.o, Jun 08 '22 at 17:18

I'm not sure what you mean exactly by "letting python know of the existence of None," but you can easily convert the string to a dictionary by using the eval function like so:

json_entry = eval('{"a": None}')
print(json_entry["a"])

Output:

 None
