Tkinter

[Jason Swails]

Please keep response replies to the Python list (e.g., use 'reply all' or
just send the email to python-list).

Also, you should tell people what Python version you are using. I assume
you are using Python 2 since Tkinter was renamed to tkinter in Python 3.

Finally, do not top-post.  Type your responses inside the body of the email
you are responding to.  That gives people context for your responses.

I'm not sure exactly what you are trying to do.  My guess is that you want
to get "numero" from user input.  Luckily, the tkSimpleDialog module
contains a handy function that does just this: askinteger.  So add a call:

numero = tkSimpleDialog.askinteger('Window Title', 'Please insert the
number of input values you want')
window = makeWidgets(numero)
window.mainloop()

I leave to you the task of bringing tkSimpleDialog into your namespace.

Good luck,
Jason
