 When you type text in Word, you press Enter at the end of a line. The editor puts a special invisible character at the end of the line called LINE FEED (LF). In some editors, you can actually display the invisible characters. Then the text will look something like this:

 - '\n' — один символ, несмотря на то, что в коде он записан как два (\ и n).
 - Если вы хотите вывести символы \n буквально (как текст), используйте двойной обратный слэш `\\n`:
-
-  ```python
-  print("Joffrey loves using \\n")
-  # => Joffrey loves using \n
-  ```
+    ```python
+    print("Joffrey loves using \\n")

 - На Windows по умолчанию используется комбинация \r\n, но в Python (и вообще в кроссплатформенной разработке) принято использовать только \n, чтобы избежать проблем при переносе кода между системами.
