One of the amazing things about Python is how quickly you can get started writing code. Within a few days or weeks, you can be writing useful, sophisticated applications that solve real business problems.
But then you’re faced with a different sort of problem: How do you organize your code, so that it’s easier to understand, reuse, and debug?
Most programming languages offer libraries, and Python is no different. We call them “modules,” and they offer us not only the chance to keep reusable code in separate, loadable files, but also to separate our variables into namespaces. Knowing how to use modules, how the module-loading system works, how to write modules, and how to use third-party modules on the Internet are all part of being a modern Python developer.
In this course, I teach you how to use modules in your day-to-day work: We see how to import them (including the different forms of “input”), how to write them, and how to download them from PyPI using pip. We even go through a number of useful modules in the Python standard library, so that you can get a better idea of what’s available and how to use it.
We also discuss virtual environments, a common technique to ensure that package installations from one project don’t interfere with another.
If you program in Python and don’t yet have a robust understanding of how to use, write, and distribute modules, then this course is for you.

Reuven is a full-time Python trainer. In a given year, he teaches courses at companies in the United States, Europe, Israel, India, and China — as well as to people around the world, via his online courses.
Reuven created one of the first 100 Web sites in the world just after graduating from MIT’s computer science department. He opened Lerner Consulting in 1995, and has been offering training services since 1996.
In 2020, Reuven published “Python Workout,” a collection of Python exercises with extensive explanations, published by Manning. He’s currently finishing edits on “Pandas Workout,” a similar collection of exercises using the “Pandas” library for data analytics.
Reuven’s free, weekly “Better developers” newsletter, about Python and software engineering, is read by more than 30,000 developers around the globe. His “Trainer weekly” newsletter is popular among people who give corporate training.
Reuven’s most recent venture is Bamboo Weekly: Every Wednesday, he presents a problem based on current events, using a public data set. And every Thursday, he shared detailed solutions to those problems using Pandas.
Reuven’s monthly column appeared in Linux Journal from 1996 until the magazine’s demise in 2019. He was also a panelist on both the Business of Freelancing and Freelancers Show podcasts.
Reuven has a bachelor’s degree in computer science and engineering from MIT, and a PhD in learning sciences from Northwestern University. He lives in Modi’in, Israel with his wife and three children.
