Practical Python – Workshop eBook



Dear readers,

You probably already know that we have an online course called Practical Python. It’s full of theoretical materials, assignments, access to the Instructor and final test to check your knowledge. After completing all of the assignemnts and final test you will recieve a certificate. So that’s some work to do!

For those of you, who would only like to take a look, practice or fill the knowledge gaps, we decided to prepare PRACTICAL PYTHON WORKSHOP EBOOK. It is still paid, but it only containes theoretical materials, so it’s cheaper than the course itslef. It’s a great opportunity to those of you, who have been thinking about taking the course, but aren’t sure, if that’s something for you.

This e-book will be added to the course as a free download, for those of you who participate in the course. All materials here were written by our instructor, Rui Silva.
