How to make `jsons.dump()` treat `bytes` the same as Python3 `str`?

[johnnyutahh]

How can one make jsons.dump() treat bytes the same as Python3 str? Some sort of serializer/class/setting change/override, perhaps?

On my system (below) jsons.dump() prints my bytes type variables in a List-like format, even when assigning said variables a str literal (I think... maybe I don't understand Python3 properly? Quite possible). The pertinent excerpt:

"{'originally_bytes_type': ['1', '2', '3', '4'], 'originally_str___type': '1234'}"

All the context:

$ cat jsons-dump-string-type-test.py
#!/usr/bin/env python3

from dataclasses import dataclass
import jsons

@dataclass
class strs_and_bytes:
    originally_bytes_type : bytes
    originally_str___type : str

sandb1 = strs_and_bytes \
(
    originally_bytes_type = '1234' ,
    originally_str___type = '1234' ,
)

print('"' + str(jsons.dump(sandb1)) + '"')
$ python3 jsons-dump-string-type-test.py
"{'originally_bytes_type': ['1', '2', '3', '4'], 'originally_str___type': '1234'}"

Hi @johnnyutahh ,

Try this:

jsons.set_serializer(lambda obj, *_, **__: obj, bytes)

[johnnyutahh]

This works, thanks @ramonhagenaars!

Details:

$ cat jsons-dump-string-type-test.py
#!/usr/bin/env python3
