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.
