How to iterate over case-insensitive, sorted dictionaries?

Question

Example:

>>> d = {'answer':1, 'Question':2} >>> for i, j in sorted(d.items()): print i Question answer 

I need case insensitive case:

 answer Question 

and I believe that this can be done in a simple Putin way.

Answer 1

If it just prints the keys:

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

If you need values ​​after this, you can 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) 

Answer 3

 for k in sorted(d, key=lambda k: k.lower()): print k
