Comprehensions are one of the most powerful tools in a Python developer’s toolbox. But they are also hard for many people to understand, and are often ignored in favor of traditional “for” loops. In this course, you’ll learn not only what comprehensions are, but how they work, how and where you can put them to use, and why they should be used instead of “for” loops. You’ll even see (and finally understand) nested comprehensions, and use them to work through complex data structures.
If you have been avoiding the use of comprehensions because they seem too complex or difficult, 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.
I send a full-length Python article to more than 30,000 people each week — on topics ranging from iterators to descriptors, variable assignment to sets, exceptions to command-line arguments. Join me, and get smarter about Python each week!
