Variables in programming are abstract local storages for values. In the previous section, you calculated some math expressions. What if we need some of the numbers in the future? Recalculating seems a bit irrational.

To refer to a specific value in the future, we need to use a particular name for the variable. Use the equality sign `=` for assigning value to a variable. For example, you can assign the value `2022` to the variable `year`, and then output it or perform any arithmetic operation using its name.

# Create a variable
year = 2020
# Output its value
print(year)
# Perform an addition
print(year + 10)

## Task

This is the seventh chapter of the course. Create a variable `chapter` with a value of `7`.

In this section, you will be introduced to the very basics of Python and to your workspace, learn some simple math operations, and print your results.

In this section, you will learn how to store numbers, text, etc. in computer memory and then be able to call them by name. Also, you will learn little manipulation with text in Python.

In this section, you will learn the next data type - boolean - and how it can help in creating programs that behave differently depending on certain conditions. 

In this section, you will continue learning different data types in Python: This time you will learn how to store different characteristics inside one variable using lists, tuples, and more interesting type dictionaries.

In this section, you will learn how to write loops in Python - things often used to iterate over a list, tuple, dictionary, or even in a future dataframe...

In the final section of our introduction course, you will learn a bit about built-in functions and then write some functions by yourself!
