Hey, welcome to the forums.
In the future, you can use “Preformatted text” option to make your code be easily readable and display nicely. This menu is just above the message box, when you’re writing or editing a post.

E.g:
for i in author_names:
print(i)
as preformated text would show like this:

for i in author_names:
    print(i)

PS I also didn’t know about it at first
