I'm getting data back from a library. How do I get both the keys and the data in JSON format?
It appears to not have a dict property, so I don't know how to inspect it. vars(obj.rect), fails.
I feel like this must be something super-simple -- I can see the properties (left, right, etc.), but when json just dumps the values, not the keys.
[Edit] user2357112 pointed me in the right direction, so I'm halfway there. Rect is a namedTuple, printing the json works by adding asdict(), but polygon is a array, how do I encode that as json? Obviously, I can loop through, but there must be a more generic way.
print('Rect : ', obj.rect)
print('rect.json : ', json.dumps(obj.rect._asdict()))
print('polygon : ', obj.polygon)
# polygon is an array of named tuples, so this fails.
print('polygon.json : ', json.dumps(obj.polygon, skipkeys=False))
Rect : Rect(left=2264, top=1031, width=241, height=238)
Rect.json : {'left': 2264, 'top': 1031, 'width': 241, 'height': 238}
polygon : [Point(x=2260, y=131), Point(x=2261, y=367), Point(x=2500, y=360), Point(x=2502, y=119)]
polygon.json : [[2260, 131], [2261, 367], [2500, 360], [2502, 119]]
Obviously, skipKeys isn't the answer. I've hacked away with .dict, but that's not working. I'm new to python, so not even sure how to debug what Rect and Polygon are.
