Dictionary

[Serge Beaumont]

I tried it in the interactove window to be sure:

i did this:

tup = ('A', 'B')
dict = {'A': 100}

dict[tup[0]]
100

So it should work. The key error occurs when you try to find a key that
isn't there. So either tup[0] is not 'A', or dict does not have a 'A'
key or both. Remember that Python is case sensitive...
