I have to define a function add(c1, c2), where c1 and c2 are capital letters; 
the return value should be the sum (obtained by converting the letters to 
numbers, adding mod 26, then converting back to a capital letter).


I'd say the requirement is lacking in that no encoding is specified.

All I have so far is:

def add(c1, c2):
     ord(c1) - ord('a') + 1
     ord(c2) - ord('a') + 1

I know I need to use ord and chr, just not sure how.


I'll further observe from your later replies that you're suffering from the highly contagious, highly virulent double line spacing disease. This is known to cause severe eye strain leading to blindness. In can be cured by purchasing medication here https://wiki.python.org/moin/GoogleGroupsPython
