Class JSONEncoder

Implement this method in a subclass such that it returns a serializable object for ``o``, or calls the base implementation (to raise a ``TypeError``).

For example, to support arbitrary iterators, you could implement default like this:

   def default(self, o):
       try:
           iterable = iter(o)
       except TypeError:
           pass
       else:
           return list(iterable)
       # Let the base class default method raise the TypeError
       return JSONEncoder.default(self, o)

Overrides: json.encoder.JSONEncoder.default
