Hi everyone,

The below code is not working with Processing.py (instead of the passed arguments the default values for width and height applies, that are 100x100 pixels: same results as size() statement, with no arguments):

```auto
square_size = 10
square_x_nb = 50
square_y_nb = 100

size(square_x_nb * square_size, square_y_nb * square_size)

```

It works fine with absolute values arguments but not with variables arguments, that is:

```auto
size(1000, 500)

```

Any idea?

When you need to define the parameters of the size of the display window with a variable, you must use the settings() function and define size() in it. 🙂

Thanks GoToLoop and hsron for your quick and clear answer!

For the above code, the solution would be:

```auto
square_size = 10
square_x_nb = 50
square_y_nb = 100

def settings():

  size(square_x_nb * square_size, square_y_nb * square_size)

```

Just noting that the Python Mode reference has an entry for `setup()`, but no equivalent documentation for `settings()`.

[https://py.processing.org/reference/setup.html](https://py.processing.org/reference/setup.html)

This might be worth opening as an issue for documentation on the python mode docs site:

That **settings()** issue strikes again: 🎳
