and I believe it can be done in simple Pythonic way.

Answer 1

If it's just about printing the keys:

for i in sorted(d.keys(), key=lambda x: x.lower()): print i

If you need the values afterwards, you could do

for i, j in sorted(d.items(), key=lambda x: x[0].lower()): print i, j

EDIT: Even shorter and better (since you have d in scope):

for i in sorted(d, key=str.lower):
    print i, d[i]

Answer 2

import string
sorted(d.items(), key=string.lower)
