def prtC(val):
print val
print sel.cget('value')
root = Tix.Tk()
fruits=Tix.Select

You can write these four lines much simpler as:
junk = sys.argv[1:]
if len(junk) is 0 and empty ==

Good morning Julias,
The python tutor list is a give and take of python information.
If can contribute to an explanation or resolve a problem, then please do
so.
Additionally, you can read the e-mail messages and learn from others on

Thank you,

In your usage, you are calling DNA() and passing the result of the
call to failUnlessRaises(). The
