Well, `json` and the other modules could add another standard: `serialize` and
`deserialize`
As an example, this is how I deserialize from a custom class:
def __init__(self, source):
path = None
try:
# most common case: JSON string
self._data_raw = json.loads(source)
except TypeError:
try:
# check if it's a dict-like object
source.items
self._data_raw = copy.deepcopy(source)
except AttributeError:
try:
# maybe a file object?
self._data_raw = json.load(f)
except AttributeError:
# maybe a PathLike?
path = source
except JSONDecodeError:
# maybe a path string?
path = source
if path:
with open(path) as f:
self._data_raw = json.load(f)
Apart the `dict` check, this logic could be applied to a `json.deserialize()`
function. Python let you function overloading more simple, so why not use it?
