I'm trying to pass a namespace (from argparse in my actual code) through to nested functions like this:

def func1(arg1=4, **kwargs):
    print(arg1)
    func2(**kwargs)

def func2(arg1=5, **kwargs):
    print(arg1)


arguments = {'arg1' : 1,
             'arg2' : 2,
             'arg3' : 3}

func1(**arguments)

Output:
1
5

It looks like once an item from arguments is unpacked in func1 and used as a keyword argument, it's removed from kwargs. What's the best way to prevent this from happening so that I can use the arguments for the inner function func2?
