For example, in the prior chapter’s sprite example,Ī programmer could move the sprite class into a separate file. By separating a large program into several smaller programs, it isĮasier to manage the code. Some of the programs already created in this book have started to get rather The code written can be easily shared with other programmers. It allows multiple people to work on a program at the same time. It breaks the code into smaller, easier to use parts. There are three major reasons for a programmer to create his or her own This chapter shows how to create a module, and how to import Modules are not loaded unless the program asks them to. For example, the arcade module contains submodules for Modules can be organized so that individual modulesĬontain other modules. Programs have already used functions from the math module, the random module,Īnd the arcade library. Modules are often organized into groups of similar functionality. Often a library only has one module, so these words can sometimes be A library can be made up of multiple modules that can be The programmer does not have to “reinvent the wheel.” In Python the term usedīy using import arcade and import random, the programs created so far haveĪlready used modules. Libraries are written by someone else and brought into the project so that A library is a collection of code for functions and classes.
