Making tabulation look different than just whitespace

Question

How to make tabulation look different than whitespace in vim (highlighted for example).

That would be useful for code in Python.

Answer 1

I use something like this:

set list listchars=tab:»·,trail:·,precedes:…,extends:…,nbsp:‗

Requires Vim7 and I'm not sure how well this is going to show up in a browser, because it uses some funky Unicode characters. It's good to use some oddball characters so that you can distinguish a tab from something you may have typed yourself.

In addition to showing tabs, showing spaces at the end of lines is useful so you know to remove them (they are annoying).
