kwargs in Python

Question

Uses for **kwargs in Python?

I know you can do an objects.filter on a table and pass in a **kwargs argument.

How exactly does it work? Is it classes as 'unpacking'? Like a,b=1,2?

Answer 1

kwargs in **kwargs is just variable name. You can very well have **anyVariableName

kwargs stands for "keyword arguments". But I feel they should better be called as "named arguments", as these are simply arguments passed along with names (I dont find any significance to the word "keyword" in the term "keyword arguments".  we give namesparam1 and param2 to two parameter values passed to the function as follows: func(param1="val1",param2="val2"), instead of passing only values: func(val1,val2). Thus, I feel they should be appropriately called "arbitrary number of named arguments" as we can specify any number of these parameters (that is, arguments) if func has signature func(**kwargs)
