There is a more advanced slicing technique that exists. It allows us to extract all the elements in a specific range with a specific step set.

To set this step, we need to put it as the third number after the second colon as follows: `s[start:end:step]`. Let's consider a simple example: given string `s`, and we want to understand what will be extracted after the following code execute: `s[1:10:2]`. This will extract each second element starting from index 1: 1, 3, 5, 7, 9.

In this section you will be introduced with the basic concepts of strings in Python, such as creating, indexing, and slicing.

In this section we will learn important strings methods, like .split, .count, .strip and so on...

In this section we will learn how to format strings, learn about f-string conception, replacing particular parts of strings, splitting string by lines and so on...
