Introduction
The key argument
The itemgetter() function
Instruction
Great! In the previous exercise, we used the following code to sort all the products by the third element of each tuple:
products.sort(key=lambda product: product[2])
Python provides an alternative way of indicating which tuple element should be used for sorting. Take a look:
from operator import itemgetter products.sort(key=itemgetter(2))
The itemgetter() method from the operator module makes picking a tuple element easier than writing your own lambda. Let's give it a try.
Exercise
Import itemgetter from the operator module. Sort all the employees in the template code by salary, in descending order. Modify the employees list and print the result.
Stuck? Here's a hint!
Use two parameters: key and reverse.
