You might be accustomed to specifying numbers in ways such as:  
- `1,000,000` (with commas);  
- `1 000 000` (with spaces).
  
However, Python will not understand this. 😢 

These formats are understandable for a person but not for a computer, so the right way is `1000000` without commas or spaces.

```python
var = 1000000
```

If you want to use separators for better readability, Python allows the following syntax:
```python
var = 1_000_000
```

This course is going to help you dive deeper into data types and try to work with them. Here you will learn basic operations and all ins and outs of numbers, boolean data type, and strings. This course consists of a lot of practical tasks after which you will become a skillful programmer.

Numeric data types are crucial in Python, so it is important to start with them. Here you will work with simple math operations and find out the purposes of learning different types of numerical data.

Mastering boolean data types and logical operations in Python. You'll learn how to work with True and False, apply logical operators like and, or, and not, and understand how operator precedence works in complex expressions.

Strings are a way for us to implement your phrases in Python, that is, to give instructions to users who are the target audience of your program. Indeed, it is always better to be able to work with strings because they should be used in your code. You'll understand why soon.

This chapter consists of practical tasks that combine all the examined topics together with a bit of theory.
