1. Introduction to Python 1/2

Here, we will face challenges related to data types in python. In this section, we will learn the Python syntax necessary for each person who wants to work with this language. After the section, we will undoubtedly be able to cope with simple Python tasks.

First Step in Programming

Deal with Variables

Practice Math Skills

Deal with Percents

How to Attract One User?

Boolean Numbers

Work with Strings

Get Familiar with Lists

How to Append New Element?

2. Introduction to Python 2/2

This section will teach you simple Python functions. We will be able to work with if/else statements and loops. Such skills are necessary for everyone who wants to start programming and doing fascinating Python tasks.

3. Explore Dataset

This section is the most complicated than the previous one, but it is gripping. Here, we will manage the most commonly used pandas function to help we do essential operations with data. Also, we will learn the basics of the NumPy library.

Boolean Numbers

The following data type is crucial for us; it helps check if a specific condition was satisfied.

Imagine that you want to store data about users who continued subscriptions after a trial period and who canceled.

The best way is to divide users into two groups: False if users canceled the subscriptions and True if one continued. We can create a table where one boolean value (True or False) will correspond to the statuses of users' subscriptions. We will practice it in the next chapter.

There are two ways to define several conditions:

With the or statement: here, if at least one condition equals True, the whole statement equals True; otherwise, it is equal to False. Look at the examples:

With the and statement: here, if at least one condition equals False, the whole statement equals False; otherwise, it is equal to True. Look at the examples:
