I've been trying for a while now to find out if there is a way to pass variables to the `geometry`

method in Tkinter.

I know the `geometry`

method accepts a string:

```
root = Tk()
root.geometry("1200X1024")
```

I want to open the window based in the screen width.

```
root = Tk()
w = root.winfo_screenwidth()
h = root.winfo_screenheight()
```

What I've tried is this:

```
geometry = "%dX%d" % (w,h)
root.geometry(geometry)
```

or

```
root.geometry(("%dX%d" % (w,h)))
```

No matter how I concatenate the variables it gives this error:

```
TlcError: bad geometry specifier "1280X1024"
```

So is it possible to pass variables to the `geometry`

method?
