New submission from David Gene <da...@astrosticks.com>:
Using os.environ[KEY] with a non-existent environment variable key only gives a
simple KeyError, which may be fine for a developer to understand, but if a user
of a Python program were to come across it, it may not indicate what they
needed to do to avoid the crash. I would raising the keyError with a message
such as "Environment variable '{}' not set".
