In the first chapter, you learned how to make Python output the message `"Hello, Python!"`. This message is called a *string*. In Python, strings represent textual data (they may contain numbers too).

To store text in Python, you need to enclose it within quotation marks (single or double). For example, we can save the word Python within the `language` variable and output it.

# Save string within variable
language = 'Python'
# Output string
print(language)

> Note that using quotation marks is compulsory. If you don't use them, then an error will be raised.

Assign the course name ('Introduction to Python') to the `course` variable and output it.

Python is an interpreted high-level, general-purpose programming language, which means it can be used in different spheres of human activity (unlike HTML, CSS, and JavaScript, which are mainly used in web development). Python can be used in software developing, data science, back-end development, etc. In this mobile-friendly version of the course, you will meet with the main aspects of Python.

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.
