Summary

In this chapter, we introduced the concept of modules and packages in Python. We discussed how to build reusable modules and how they can be imported by other modules and programs. We also covered the loading and initializing of modules when included (by an import process) by other programs. In the later part of this chapter, we discussed building simple and advanced packages. We also provided a lot of code examples to access the packages, as well as installing and publishing the package for efficient reusability.

After going through this chapter, you have learned how to build modules and packages and how to share and publish the packages (and modules). These skills are important if you are working on a project as a team in an organization or you are building Python libraries for a larger community.

In the next chapter, we will discuss the next level of modularization using object-oriented programming in Python. This will encompass encapsulation, inheritance, polymorphism...
