Why can't I stop vim from wrapping my code?

Question

I know there must be something obvious I'm missing, but I can't stop vim from wrapping my python code. I enter :set nowrap like a champ, but still it wraps. I can hit J to unite the split lines of code, so it seems like a real carriage return is being inserted, I just don't understand why or how to stop it.

Answer 1

To disable line wrap, you can enter :set wrap! or append this command to your ~/.vimrc.

Answer 2

set formatoptions-=t should do the trick. set formatoptions+=t will turn auto-wrapping back on.
