Drawing on JSON datetime between Python and JavaScript, I'd go with something closer to this: This can be made cleaner/saner/safer (in particular, just grabbing __dict__ isn't generally a recommended thing to do outside debugging/troubleshooting), but it should get the point across. how might I omit the name attribute from the Identity object?). It does nested serialization of Python objects and can easily be extended to serialize custom types. Deeply Nested "JSON". Making location easier for developers with new data primitives, Stop requiring only one assertion per unit test: Multiple assertions are fine, Mobile app infrastructure being decommissioned. The first is a JSON object describing the car, and the second is a Python dictionary with the same values. This will output exactly what you where asking for: More elegant solution to enable serializing and de-seralizing. You just finished reading an article and emancipated some matryoshka dolls at the meaning time. Although all the other solutions I assume they work I find they do have a lot of boilerplate code, when the goal is to only encode nested python objects. The particular key or keys can be mentioned for sorting when the lambda is used for sorting. myobject is the Python Class object and myobject.__dict__ gets the dictionary version of object parameters.

JSON datetime between Python and JavaScript, Making location easier for developers with new data primitives, Stop requiring only one assertion per unit test: Multiple assertions are fine, Mobile app infrastructure being decommissioned. The python dump function is used by importing packages like json and pickle in python and the basic syntax for both the functions is, json.dump (object, skipkeys=False, ensure_ascii=True, indent=None, allow_nan=True, number_mode = None, datetime_mode = None, separators=None) pickle.dump (Object, Destination, pickle_protocol=None, ) json .
