You can do that in Python 3.
def func(a,b,*args,kw1=None,**kwargs):
The bare *
is only used when you want to specify keyword only arguments without accepting a variable number of positional arguments with *args
. You don’t use two *
s.
To quote from the grammar, in Python 2, you have
parameter_list ::= (defparameter ",")*
( "*" identifier [, "**" identifier]
| "**" identifier
| defparameter [","] )
while in Python 3, you have
parameter_list ::= (defparameter ",")*
( "*" [parameter] ("," defparameter)*
[, "**" parameter]
| "**" parameter
| defparameter [","] )
which includes a provision for additional parameters after the *
parameter.
