You can set attributes on functions, so if your class is just storing
this data, rather than altering the behavior of the function, you may be
able to just use a function:
def f(x, y):
"x * y"
return x * y
f.arguments_max = [1000, 255]
A function also already knows how many arguments it takes, which you can
access as f.func_code.co_argcount
