Create Closures

Introduction

This is the first lesson of chapter 12 in the Comprehensions, Lambdas, Closures, and I/O section of PCAP-31-03 (22% of the score, 9 of 40 items). It covers objective 5.3: closures, that is, functions that remember values from the scope in which they were created. A closure is the natural next step after chapter 11. There you learned that a function is an object that can be stored, passed and returned. Here you will see what happens to the variables that such a function uses when the function that created it has already finished.
