Dear list,
one of the exercises in Zelle's book is:
given
import string
s1 = "spam"
s2 = "ni!"
show a Python expression that could construct the following result by
performing string operations on s1 and s2:
"Spam Ni! Spam Ni! Spam Ni!".
I have two solutions:
a)

Hello!!
I just completed exercise 7 (chapter 4) in Zelle's book:
"A certain CS professor gives 100-point exams that are graded on the
scale 90–100:A, 80–89:B, 70–79:C, 60–69:D, 60:F. Write a program that
accepts an exam score as input and prints out the corresponding grade."
I am quite happy

The behavior I seek is that one and only one Toplevel window
gets generated no matter how many times the original Tkinter
button is pressed.
Here is a minimal example of what I think you want?
Does that help?

I think tuple unpacking makes code like this more readable:

Not sure how the dict is better - in either case, leaving off the
grade corresponding to a score of 100 will raise
When I run it from the idle it works perfect, but when I run it from a
file I get none, why is that?

The value returned from raw_input() is a string; you have to convert
David try this:
score = input("What is your exam score: (0-100)? ")

Lots of good responses. And now for something completely different:
import string
x = string.maketrans('567891', 'FDCBAA')
score = raw_input('score>')
print "Your grade is:", score[0].translate(x)

AFAIC there is no particular reason to use Temp file. It is a
