Seriously, or is that a rhetorical question?
People who like to have two source files side-by-side on a standard
sized monitor, or three on a wide-screen monitor.
People who need to read or edit source code on a virtual terminal rather
than in a GUI console app.
People who print out source code to read later.
People with poor vision who need to use a significantly larger sized
characters, and therefore can't fit as many on a line.
People who might want to email code snippets without having them
inconveniently wrapped by the mail client.
People who don't like reading really long, overly complex, lines, and
prefer to keep lines short for readability.
And most importantly... people who want to have their code accepted into
the Python standard library.
Personally, I find that the discipline of keeping to 80 characters is
good for me. It reduces the temptation of writing obfuscated Python one-
liners when two lines would be better. The *only* time it is a burden is
when I write doc strings, and even then, only a small one.
