And you have a SECOND problem ... rebinding your loop counter is
likely to confuse anybody (including yourself!) who tries to
understand (let alone maintain!) your code. If you want a to have
values 0, 100, 200, 300, 400 as the loop is traversed, you should use

   for a in range(0, 500, 100):

or maybe you want 100, ...., 104 which would be produced by
EITHER
   for a in range(100, 105):
OR
   for c in range(5):
       a = c + 100

Note that chr(a) will cause an exception when a >= 256 ... do you need
unichr()?

AND what is the point of this dicky diky anyway? Have you considered
the ord() function?

As expected; the last value of a was 104 and ord('h') == 104 ...
