Hello, Alikont: code blocks using backticks (“`) don’t work on all versions of Reddit!
Some users see this / this instead.
To fix this, indent every line with 4 spaces instead. It’s a bit annoying, but then your code blocks are properly formatted for everyone.
An easy way to do this is to use the code-block button in the editor. If it’s not working, try switching to the fancy-pants editor and back again.
