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

Question

I can\'t stop vim from wrapping my Python code. If I enter :set nowrap like a champ, but it still wraps.

I can hit J to unite the split lines

Answer 1

Maybe it's the textwidth that's set, which automatically breaks lines when it reaches a certain length Try

:set tw=0

If that fails play with e.g.

:set wrap linebreak textwidth=0 

and

:set virtualedit=insert
