Deliberate itemgetter(0,-1)

from operator import itemgetter

grade = [(‘Freddy’, ‘Frank’, 3), (‘Anil’, ‘Frank’, 100), (‘Anil’, ‘Wang’, 24)]
sorted(grade, key=itemgetter(1,0))

sorted(grade, key=itemgetter(0,-1))

What is this?

For usage of
operator.itemgetter(item )
operator.itemgetter(*items )
Scroll through the operator docs until the section operator.itemgetter

Do you have a question about the code, or are you just trying to showcase something?

Can you explain itemgetter(0,-1), is it taking elements by index -1,-2,-3 or by alphabet Anil, Freddy.
