In the previous chapters, you operated with numbers. There are many variants of number classifications in math (negative/positive, rational/irrational, etc.). How does Python distinguish between numbers? There are three numerical types in Python:
- `float` - represents a floating-point number
- `int` - represents an integer/whole number
- `complex` - represents a complex number

We won’t focus too much on complex numbers, since this is a branch of Further Mathematics. To get the type of a certain value/variable, use the `type()` function. For example, let's output the types of the numbers `5` and `10.5`.

# Creating the variables
number1 = 5
number2 = 10.5
# Output the types of numbers
print(type(number1))
print(type(number2))

Which of the following answers is not a Python numerical type?

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.
