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 p,q=1,2?

Answer 1

**kwargs is short for key worded arguments, they allow you to pass an arbitrary number of key-worded arguments and will be received by the function as an dictionary with keys as the keywords and values as values passed by the user.  e.g.:

def my_function(**kwargs):

    print(kwargs)

my_function(name="Anirudh")

The above code will print {'name': 'Anirudh'}
