Hi Mark,
First problem:
you need to assign the command for the button without parenthesis:
b = Button(main, text='OK', command=go)
b.pack()
I split the line you used into two lines, because pack() returns None , so you
don't have a reference
to the button once you created it. Of course you can do it the way you did if
you don't need to reference
the button anymore, however there's not much use in assigning a new variable to
it, just write:
Button(main,text='OK',command=go()).pack()
Second problem:
your go() function does just what you told it to: it prints the "window name"
(or however this is called) of
the entry widget. You surely meant something like this:
def go():
contents = e.get()
print contents
or simply:
def go():
print e.get()
I hope this helps
Michael
