[Tutor] sorting based on elements which are nested in a list

[ranjan das]

I have a list which I want to sort based on ('a','b','c') first and then
based on (1,2,3)

How do i do these using itemgetter() since the list is nested


A=[('k3', ['b', 3]), ('k2', ['a', 1]), ('k1', ['a', 3]), ('k4', ['c', 2])]


The solution I am looking for is

A_sorted=[ ('k2', ['a', 1]), ('k1', ['a', 3]), ('k3', ['b', 3]) ('k4', ['c',
2])]

Please suggest

Regards,
ranjan
