No. There is no way to represent NaN in JSON. It's simply not part of the
specification.
I know that. I'm trying to emit the *string* 'N/A' for every NaN.
Easiest way is probably to transform your object before you try to write
it, e.g.
def transform(x):
if isinstance(x, dict):
return dict((k, transform(v)) for k, v in x.items())
elif isinstance(x, list) or isinstance(x, tuple):
return [transform(v) for v in x]
elif isinstance(x, float) and x != x:
return 'N/A'
else:
return x
Note that for a self-referencing object, this function might run
"forever," or until it runs out of stack. The programmer is likely to
know about the possibility, but just in case ...
Then just use
json.dumps(transform(x))
rather than just
json.dumps(x)
