Example-2: Python sorted() with key function

# take third element for sort
def takeThird(elem):
    return elem[1]

# random list
random = [(2, 2), (3, 4), (4, 1), (1, 3)]

# sort list with key
sortList = sorted(random, key=takeThird)

# print list
print('Sorted list:', sortList)

Output:

Sorted list: [(4, 1), (2, 2), (1, 3), (3, 4)]
