I'm relatively new to programming as a whole and some tutorials have been telling me to use ls -l to look at files in a directory and others have been saying ll. I know that ls is a short list, but is there a difference between the other two?

This is located in your .bashrc:
alias ll='ls -al'
By taking a look at the manual pages for the command ls, you can see what those two attributes accomplish together:
-a: do not ignore entries starting with..-l: use a long listing format.
So you can understand that ls -l would ignore any entry starting with .. That's their only difference.
EDIT:
Let me note, that, as commented, the ll alias differs from installation to installation. In case you are wondering what's yours, please open up a terminal and enter:
alias ll
This will show you how ll is set. You can then look up the additional attributes by typing:
man ls

3I have
ll is aliased to 'ls -l'... The alias is copied over from the skeleton files so what people have depends on when they installed.– Oli ♦Feb 4, 2015 at 9:57 -

ls='ls --color=auto',ll='ls -lh'. Ubuntu 14.04 ships/etc/skel/.bashrcwithls='ls --color=auto'll='ls -alF, but that's horrible. I usellwhen I want sizes/dates/perms,ll -aif I also want dotfiles. Feb 4, 2015 at 19:21 -

2For your explanation of
-a, you might want to put.in backticks so it's more visible.– cpastFeb 5, 2015 at 5:50
ll is a common alias for ls -l. It is a part of the default .bashrc, with a couple more options:
$ grep 'alias ll' /etc/skel/.bashrc
alias ll='ls -alF'
type [command].type llresults inll is aliased to 'ls -alF'in my setup.
