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)

When we take the time to be aware of our feelings and 
needs we have more satisfying interatctions with others.

Nonviolent Communication provides tools for this awareness.

As a coach and trainer I can assist you in learning this process.

What is YOUR biggest relationship challenge?

Wow! Bob Gailer's solution is so elegant. Can someone plese explain what is the algorithm behind  string.maketrans. More exactly, how is this function doing the coding?
