Comprehending comprehensions

Comprehensions — list, dict, and set — are a powerful Python feature that make your code shorter, more efficient, and more expressive. However, a large number of Python developers think of comprehensions as nothing more than “for” loops with a hard-to-understand syntax, and avoid using them. That’s a shame, because comprehensions aren’t that hard, and are quite useful for solving a wide variety of problems.

This course will explores comprehensions, starting with the basic syntax and use cases, working up to nested comprehensions that allow us to solve more complex problems. The course includes a large number of hands-on exercises, as well as an even larger number of live-coding demos.

By the time the course is over, you will no longer wonder when or how to use comprehensions. Instead, you’ll know how, when, and why to use comprehensions, making you a more fluent Python developer.

What you’ll learn

• How list, set, and dict comprehensions work
• When to use comprehensions, and when to use regular “for” loops
• How to solve problems elegantly with comprehensions
• How nested comprehensions work, and when you should use them
