I have created a python dictionary which has keys in this form :

11, 10, 00, 01, 20, 21, 31, 30

The keys are string

I would like to maintain my dictionary in these sorted order:

00, 10, 20, 30, 01, 11, 21, 31 

This is based on the second value of the key.

I tried this sorted(dict.items(), key = lambda s: s[1]) and got the keys like:

20, 30, 21, 31, 01, 11, 10, 00

Can somebody guide me?

You almost had it, but the key is the first item of the tuple:

sorted(dict.items(), key=lambda s: s[0])
