If you're just too lazy to indent a huge number of lines, you can select it and click on the **`{}`**-button in the panel above the text field where you enter your post.

Another possibility is to use the HTML tag pair `<pre> ... </pre>` for code formatting. It means "preformatted text" and looks the same as code blocks indented with 4 spaces.

Example (written with indentation to escape the HTML tag and make it visible!):

    <pre>
    # Here come some code lines
    # ...
    exit
    </pre>
