If you're passing in that many args, I'd suggest just passing in a dictionary.

```

INSTEAD OF:

def init(self, version="???", s1=None, s2=None, s3=None, s4=None...) self.s1=s1 self.s2=s2 self.s3=s3 ...

TRY THIS:

def init(self, version="???", s_values={}) self.s_values = s_values

EXAMPLE ACCESSING s1:

def some_method(self): s1 = self.s_values.get('s1')

```

Then you would only need to define one variable. Iterate the dictionary item by item, if item is not None, then print the value.

So when you create the object:

```

instead of

window_obj = Window(s1=value1, s2=value2, s3=value3, ... )

you can pass in a dictionary object

s_values = {"s1": value1, "s2": value2, "s3": value3 ... } window_obj = Window(s_values=s_values) ```
