Best thing about Codecademy is they way you learn, unlike most other sites wear you can watch videos and maybe follow along with code snippets, Codecademy actually requires you to complete a small coding exercise at the end of each step, I personally believe that it great aids in the learning process In addition to that, each chapter also has a small coding test, which progresses along with you, so in chapter 1 you would end with a small exercise to make sure you fully understood what was taught, and in chapter 2 is would be a larger exercise encompassing both ch1 and 2's learning.

The short videos and tutorials are really helpful. They keep the user engaged and interested in the course. I took the python course and it was an amazing experience. It really helped my build my skills in the language and helped my research work with data cleaning process.

It is a very friendly and dynamic site that has turned boring programming and algorithm classes into something much more enjoyable, easy to understand, and practice at your own pace. It offers free and paid courses with many hours of videos consisting of simple lessons focused on taking you from knowing nothing to being able to build well-structured and designed applications.
