One of Python’s most distinctive features is the list comprehension, which you can use to create powerful functionality within a single line of code. However, many developers struggle to fully leverage the more advanced features, or use them too much, which can lead to code that’s less efficient and harder to read.

By the end of this course, you’ll understand the full power of Python list comprehensions and how to use their features comfortably. You’ll also gain an understanding of the trade-offs that come with using them so that you can determine when other approaches are more preferable.

In this course, you’ll learn how to:

  • Rewrite loops and map() calls as a list comprehension in Python
  • Choose between comprehensions, loops, and map() calls
  • Supercharge your comprehensions with conditional logic
  • Use comprehensions to replace filter()
  • Profile your code to solve performance questions

Nice course, informative and flowed at a good pace. I had an understanding on Comprehensions, this course introduced concepts that I was not aware of. Thank you.
