How to define function type by its argument name

[STofone]

func_list = []
def run_func_list(arg1, arg2):
    for func in func_list:
        func(arg1=arg1, arg2=arg2)

def func1(arg1, arg2):
    pass
func_list.append(func1)

def func1(arg2, arg1):
    pass
func_list.append(func1)

def func3(**kwargs):
    pass
func_list.append(func3)

I have a list that will be traversed and call function in it by named argument.
It supports multiple parameter forms of function.
How do i annotate func_list to tell others what it supports
