Like many people here, I don't worry much about the 80 column limit. I
make my lines of code as long as they have to be, and no longer. If
there's some obvious and easy way to fold the statement onto multiple
lines, I'll do it. If not, I won't.
This tends to result in lines that are less than 80 characters, but if
not, I don't worry about it (assuming I'm even aware of it).
I just did a little experiment. I took about 20 KLOC of python that was
largely written by me and make a histogram of the line lengths
(http://www.panix.com/~roy/length.pdf). Just by eye, I'd say "most are
less than 80, almost all are less than 100". I'd guess the average of
all non-empty lines is about 45 or so. The longest line is 273
characters:
sys.stderr.write("Error: Can't find the file 'settings.py'
in the directory containing %r.\nYou'll have to run django-profile.py,
passing it your settings module.\n(If the file settings.py does indeed
exist, it's causing an ImportError somehow.)\n" % __file__)
Would that have been better rewritten broken up into several shorter
lines? Absolutely. Such is life.
PS: I didn't write that line :-)
