Named-Named method/function arguments

Question

How can I use 'variable'-based named arguments.. better explained by example :

def blah(var, a=None, b=None, c=None): ...

more precise it is :

def blah(var, **kwargs): ... 

I want to be able to do :

named = 'b'
blah(55, named=66)

is equivalent to this:

blah(55, b=66)

Answer 1

You can store the argument(s) in a dict and pass the argument(s) via ** unpacking as keyword arguments.

named = 'b'
kwargs = {named: 66}
blah(55, **kwargs)
