### `default(o)`
|
|
|
|
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:
|
|
|
|
```default
|
|
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)
|
|
```
