In this lesson, you’ll see how to use a lambda for the key of the .sort()
method of lists. The .sort()
method has two parameters. key
is None
by default. reverse
is False
by default.
You won’t be altering reverse
, but you will be looking at key
because you can use a lambda expression to alter the behavior of .sort()
. When you use lambda
, you can extend key
to be much more versatile.
