... however, there is a tiny bug: if the $HOME
environment variable is *not* set, you will get a KeyError exception.
one solution is to add a default value to your get() method call so
that it returns an object with a Boolean False value:
No KeyError. D

Hi,
I am currently learning Python and I was wondering is there a shorter
way to do the following -
import os
homedir = os.environ.get('HOME')
if homedir:

I do this in Perl -
my $home;
if ($home = $ENV{'HOME'}) { print "My home directory is $hom
