Sort last

[DeaD_EyE]

You can use the itemgetter.

from operator import itemgetter

tup = [(1, 7), (1, 3), (3, 4, 5), (2, 2)]
sorted(tup, key=itemgetter(-1))

The itemgetter could also used to access keys in a dict:

data = [{"x": 10, "y": 42},{"x": 20, "y": 44},{"x": 13, "y": -1}]

# sort by x
sorted(d, key=itemgetter("x"))

# sort by x and then y
sorted(d, key=itemgetter("x", "y"))

# sort by y and then x
sorted(d, key=itemgetter("y", "x"))

How it works:

my_itemgetter = itemgetter(1)
# the itemgetter returns a callable, which takes the sequence as input
my_itemgetter([1,2,3])

Output:
2

If you call it in one line, it looks a bit strange:

itemgetter(1)([1,2,3])
