I've been a python dev for more than two years and somehow I didn't know that dicts can be updated by kwargs. Like this:
>>> a = {'a': 1}
>>> a.update(b=5)
>>> a
{'a': 1, 'b': 5}
So obvious, yet.

The only drawback of this is that update does not return anything so you can't use it in an expression.
There's an alternative in Python 3.5+:
this way you can merge dictionary a with b (or an in-line dict). c is the result, a and b remain unchanged.
Thanks Rhymes!
I learned it thanks to Django and csrf token :)
dictionary = dict(request=request, message=message)
dictionary.update(csrf(request))
