Classes Versus Modules

Let’s wrap up this chapter by briefly comparing the topics of this book’s last two parts: modules and classes. Because they’re both about namespaces, the distinction can be confusing. In short:

 

ModulesAre data/logic packagesAre created by writing Python files or C extensionsAre used by being importedClassesImplement new objectsAre created by class statementsAre used by being calledAlways live within a module

Classes also support extra features that modules don’t, such as operator overloading, multiple instance generation, and inheritance. Although both classes and modules are namespaces, you should be able to tell by now that they are very different things.
