This is an amazing learning experience. As someone who works with web and application developers, its great to understand how things work from the inside. The lessons are spot-on and cover things quickly and precisely. No fluff. I love that this course is covering all the things that I know developers work with everyday. This is the course I've been wanting for a long time!

I am new to Python and currently undertaking Jose's Python Bootcamp course. This course is incredibly interactive and I am so excited to have created my first few programs using the information and resources provided in this course. Jose's teaching method is enjoyable and easy to follow. Whether you're a beginner or advanced, I recommend this course as it explores the endless possibilities within Python and is comprehendible regardless of which operating system or IDE you choose to follow along with.

I had zero experience with Python or any other coding language for that matter. This course was super simple to follow along with and quickly grasp and use Python as a tool. Would absolutely recommend.

Loved it! Jose is a great instructor who has taught me a lot in his other courses; I bought this because of the positive experiences from those courses. I was not disappointed in the Complete SQL Bootcamp. 🙂 thanks Jose, I appreciate you!
