**kwargs can be used for multiple arguments which don’t really have to be specified. All the information is then stored as a dictionary.
So if we have a function like this
def myFunction(**kwargs): print type(kwargs)
and we run it like this
we get this
confirming it is a dictionary.
We could also call each argument with a loop
def myFunction(**kwargs): for str_key in kwargs: print str_key, kwargs[str_key]
If we run it with the above arguments, we should get
a1 one a3 three a2 two
