What is the purpose and use of **kwargs?

Question

What are the uses for `**kwargs` in Python? I know you can do an `objects.filter` on a table and pass in a `**kwargs` argument. Can I also do this for specifying time deltas i.e. `timedelta(hours = time1)`? How exactly does it work? Is it classes as 'unpacking'? Like `a,b=1,2`?

Answer 1

**kwargs is used for both packing named arguments into a dictionary and for unpacking a dictionary's key and value pairs into named arguments.
