Hi,
You can try the following
from Tkinter import*
root = Tk()
root.withdraw() #this will hide the main window
import tkFileDialog as tkf
f = tkf.Open().show()
tkFileDialog, requires a main window to be existing before it can show the
file dialog. If there are no main windows then it will create

Thank you for quick response!
English is not my native language so I'm going to keep my explanations simple.
This really simple script asks me for two variables called "a" and "b". For
example, I type "4" for "a" and "3" for "b" and IDLE gives me that:

Wprowadz zmienna b:
