You will master algorithmic thinking and learn how to implement algorithms in practice.
You will get to know the most important data structures.
You will learn to search for text strings using regular expressions (regexp).
You will master working with the Git version control system.
You will master the most useful commands for everyday work with the command line.
With this path you will acquire very versatile programming skills. You will need them in any field, no matter what language you might be programming in.
Knowledge of a particular language is really a secondary thing. The language itself can be mastered fairly quickly. You can also learn new languages quickly. However, there are certain skills that you will be always in need of.
Regardless of what language you're working with, you're definitely going to be writing some algorithms. And you will almost certainly need knowledge of Git. There's also a very good chance that you'll find it useful to know Unix terminal commands in your daily work. Regular expressions and data structures are also an everyday matter for many programmers. You will learn all this with this path.
Anything! This is the most versatile knowledge you will ever have the opportunity to acquire. You will use it everywhere: from writing front-end applications to managing servers. It would be pretty hard to find a field where this knowledge doesn't have practical application.
Examples of algorithms included in the path are based on the Python language. But the knowledge is presented universally so you can confidently use it in almost any technology and programming language.
