We considered the 'technical' side of naming variables in the previous chapter. At the same time, there are several conventions among programmers in regard to naming. These are:
- Variables’ names should be lowercase.
- For variables’ names that contain several words, we should  separate these words with the underscore characters (`_`).

> These rules are not compulsory, but they are recommended. For example, if you need to store the number of a user's points, it will be much better to use `points`, `num_of_points`, or `n_points` instead of `n`, `p`, or something like that.

Choose the most appropriate choices for meaningful variable names that satisfy the abovementioned conventions.

Python is an interpreted high-level, general-purpose programming language, which means it can be used in different spheres of human activity (unlike HTML, CSS, and JavaScript, which are mainly used in web development). Python can be used in software developing, data science, back-end development, etc. In this mobile-friendly version of the course, you will meet with the main aspects of Python.

In the first section, you will be introduced to the very basics of Python - how to interact with Python, perform simple operations, and output results.

In the past section, you performed different operations with numbers. In this section, you will learn how to save values in computer memory and be able to use them in the future for any purpose.

During the last two sections, you mostly worked with numerical data. In the third section, you will learn how to work with textual data in Python (strings), how to manipulate such data, what methods can be applied to them, and so on.
