My quick & dirty JSON dump that eats dates and everything:
json.dumps(my_dictionary, indent=4, sort_keys=True, default=str)
defaultis a function applied to objects that aren’t serializable.
In this case it’s
str, so it just converts everything it doesn’t know to strings. Which is great for serialization but not so great when deserializing (hence the “quick & dirty”) as anything might have been string-ified without warning, e.g. a function or numpy array.
