Get a list/tuple/dict of the arguments passed to a function?

Question

Given the following function:

def foo(a, b, c):
    pass

How would one obtain a list/tuple/dict/etc of the arguments passed in, wit

Answer 1

I would use *args or **kwargs and throw an exception if the arguments are not as expected

If you want to have the same errors than the ones checked by python you can do something like

def check_arguments(function_name,args,arg_names):
    missing_count = len(arg_names) - len(args)
    if missing_count > 0:
        if missing_count == 1:
            raise TypeError(function_name+"() missing 1 required positionnal argument: "+repr(arg_names[-1]))
        else:
            raise TypeError(function_name+"() missing "+str(missing_count)+" required positionnal argument: "+", ".join([repr(name) for name in arg_names][-missing_count:-1])+ " and "+repr(arg_names[-1]))

using with somethin like

def f(*args):
    check_arguments("f",args,["a","b","c"])
    #whatever you want
    ...
