json.load() doesn’t know anything about any conversion function you may have passed to json.dump(). What you need is the opposite of the to_json() function — a function that will take a custom-converted JSON object and convert it back to the original Python datatype.

  1. This conversion function also takes one parameter and returns one value. But the parameter it takes is not a string, it’s a Python object — the result of deserializing a JSON-encoded string into Python.
