I am not only learning Python but programming itself ; reading your posts makes me believe that nobody is that much of a beginner here. Is there a newgroup or list for my type somewhere I can't find it ?
To illustrate my case this script :
<CODE>
# function to draw rings for an Olympic flag def rings(size,offsetX,offsetY,coul): x1,y1,x2,y2 = 170, 103, 170, 103, can1.create_oval(x1-size-offsetX,y1+size+offsetY,\ x2+size-offsetX,y2-size+offsetY,\ width=8, outline=coul)
# **main****main****main****main****main****main**
fen1=Tk() can1=Canvas(fen1, bg='white', height=206, width=340) can1.pack(side=LEFT)
bou_europe=Button(fen1, text='Europe',\ command=rings(41, 100, -22, 'blue')) bou_europe.pack( )
bou_asia=Button(fen1, text='Asia',\
command=rings(size=41, offsetX=50,offsetY=22, coul='yellow'))
bou_asia.pack( )
bou_africa=Button(fen1, text='Africa',\
command=rings(size=41, offsetX=0,offsetY=-22, coul='black'))
bou_africa.pack( )
bou_australia=Button(fen1, text='Australia',\
command=rings(size=41, offsetX=-50,offsetY=22, coul='dark green'))
bou_australia.pack( )
bou_america=Button(fen1, text='America',\
command=rings(size=41, offsetX=-100,offsetY=-22, coul='Red'))
bou_america.pack( )
bou_quit=Button(fen1, text='Quit', command=fen1.quit) bou_quit.pack(side=BOTTOM)
fen1.mainloop() fen1.destroy()
</CODE>
I just cannot figure out why the rings are draw right from the start and don't wait for their buttons to be pressed before being drawn : I've written similar functions before to draw lines, rectangles and whatever else with success.
Using Python 2.3, IDLE and Win2k.
Thanks for your time

Thank you everybody !
If Tkinter hadn't been so polite... but without any error message I didn't know where to start to search. It is a shame that one can't pass parameters through 'command' in a simple manner. My intent was to make a function that could be of use in as many cases as possible. I was experimenting way off the intented target of the exercise. Nevertheless it was an occasion to learn a whole lot.
Thanks to Simon and Eric the adresses too.
