Mark, There are two problems here:
> from Tkinter import * > def go():... > e=Entry(main) > e.pack() This is OK but... > b=Button(main,text='OK',command=go()).pack() Problem 1: This will store None in b because pack() always returns None. Problem 2: > For some reason the function is called before I click the button, and > I get .10037088 before I have done a thing. Thats because you are calling go() inside the widget specification, you need to pass a reference to the function instead - ie miss out the parens: b=Button(main,text='OK',command=go) b.pack() That should fix it.
