In the last challenge, you output a message by passing necessary variables as string parts. Concatenation is a good approach, but wouldn't it be easier to pass variables within a string pattern, as if you’re completing a puzzle?

Python provides us with such functionality. The approach is called *f-strings*. To use a variable value inside the string, place the `f` letter to the left of the opening quotes and pass the variable's name within curly brackets `{}` inside the string. For example, let's output the message 'Player Alex has level 16', where Alex and 16 are stored in variables.

# Initial variables
name = "Alex"
level = 16
# Output message using f-string
print(f"Player {name} has level {level}.")

As you can see, you shouldn't worry about using strings and numerical values simultaneously with this approach.

Using the same variables as in the previous chapter-challenge (`name` and `age`), output the same message as before (**"name is age y.o."**).

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.
