Generators can only yield ints?

No. The problem is that "chr function" receives "int"
"a" and "B" are generators of "int" items.

What exactly you intent with that code?

Maybe:
#<code>
def letters():
   for i in xrange(ord('a'), ord('z')+1):
       yield chr(i)
   for i in xrange(ord('A'), ord('Z')+1):
       yield chr(i)

for letter in letters():
   print letter
#</code>
