Functions as values, lambda and key=

Treat functions as values you can store and pass around, write short lambda functions, and customise sorted(), max() and min() with key=.

You will be able to

• Assign a function to a variable and pass it to another function as an argument
• Write a function that takes another function as a parameter
• Write short anonymous functions with lambda
• Use key= with sorted(), max() and min() to sort and compare by a chosen property
