Here's another "I'd expect to have to deal with this sort of thing in
Java" example I just ran into:
>>> r = requests.head(url, allow_redirects=True)
>>> print(json.dumps(r.headers, indent=2))
TypeError: Object of type CaseInsensitiveDict is not JSON serializable
>>> print(json.dumps(dict(r.headers), indent=2))
