#102663 — [newbie] problem with geometry setting in Tkinter

I'm trying to set the geometry of my top window, but the size is
unaffected.
This is the code:

#!/usr/bin/env python
import Tkinter
top=Tkinter.Tk()
top.geometry=('900x460')
top.update_idletasks()
print (top.winfo_width())
print (top.winfo_height())
print (top.winfo_geometry())
top.mainloop()

and this is the result when running the code:
200
200
200x200+1+584


Can anyone here tell me what I am doing wrong and how to change it?
Thanks

Jens

That's an assignment, but geometry() is a method that you have to invoke:

top.geometry('900x460')

The answer is correct, however I think that in general it is wrong to 
set the geometry like this. grid and pack compute the necessary space 
for the window themselves, which adapts to the length of labels on 
buttons etc. In all GUI programs I've written, the only place to set 
window sizes in pixels have been canvas widgets, which do not have a 
native size derived from the content. Setting the size on the toplevel, 
and in absolute numbers, i.e. not computed from other sizes, is likely 
to lead to problems on different platforms, font sizes or theme changes.
