 Learning a new programming language traditionally begins with 'Hello, world!'. It is a simple program that both displays a greeting on the screen, and introduces the new language, showing its syntax and its program structure.

 This tradition is over forty years old, so we're not thinking of breaking it any time soon. In the first lesson, we'll write a program called `Hello, world!`. To do this, you have to give the computer a special command. In Python, it's: `print()`.

 Here is a simple example: in a future lesson, you will need to write a function that performs calculations and gives the answer. Suppose you make a small mistake and the function gives you the wrong number. The system will answer something like this:
 
-<pre class='hexlet-basics-output'>AssertionError: '10' != '35'</pre>
+```text
+AssertionError: '10' != '35'

 The most important thing begins after the colon: "the value of '10' is not equal to the expected value of '35'". That is, the correct function should have produced 35, but the current solution does not work correctly and produces 10.
