Question 1

you have a python object - dict for example, how do you load it into JSON, i.e. serialization?

Answer 1

json.dump(data, write_file)

string = json.dumps(data)

Question 2

you have json data (represented as string) and you want to load it into a python object, i.e. deserialization.

Answer 2

load from string:
object = json.loads(json_object)
load from file
object = json.load(read_file)

Question 3

what if you want to serialize custom object from python?

Answer 3

string = json.dumps(data, default=target_function)

target_function returns objects which python can serialize, like a list, dic, etc.

Question 4

what if you want to de serialize your custom data?

Answer 4

json.loads(data, object_hook=decode_complex)

decode_complex is a function which returns a complex object
