So, **integers** are numbers that do not contain a fractional part. These numbers can be both positive and negative (for example 10, -7 both of these numbers are integers). Let's take a look at the example below.


```
Input:
# Creating integers
x = 7
y = -10
print(f'It's a positive integer: {x}')
print(f'It's a negative integer: {y}')

Output:
It's a positive integer: 7
It's a negative integer: -10
```


Sometimes you have to check the type of some variables. In python, for it there is an useful function called **type()**. Let's look at an example of how this function works.


```
Input:
# Creating integers
x = 7
y = -10
print(f'The type of x is {type(x)}')
print(f'The type of y is {type(y)}')

Output:
The type of x is <class 'int'>
The type of y is <class 'int'>
```


A data type is a classification of data. Python, like most programming languages, supports such basic types of data as strings, numeric, and logical types.
 For programmers, one of the most important basic skills is a deep understanding of data types and data structures.
So, let's get to know Python datatypes!

In this section, we will learn basic things about the numerical type of data, what they are, how to create them and what we can do with them.

In this section we will learn about another type of data, namely Boolean, as well as how it is characterized and what to do with it.

In this section we will learn a lot about strings, as well as methods of working with them. Learn what string slicing is and practice working with it.
