A Multi-Module Inventory Report

Introduction

This lesson opens chapter 14, the integration chapter of the course. It does not introduce a new syntax. Instead it joins the five skill areas of PCAP-31-03 in one realistic program: Modules and Packages (12% of the score, 6 of 40 items), Exceptions (14%, 5 items), Strings (18%, 8 items), Object-Oriented Programming (34%, 12 items) and Comprehensions, Lambdas, Closures, and I/O (22%, 9 items). The exam does not announce which area a question belongs to. A single code sample often needs an import rule, a class mechanism, a string method and an exception rule at the same time, so you must be able to switch between them while reading.
