[PATCH] examples: sms: resolve PEP8 issues

[yegorslists at googlemail.com]

From: Yegor Yefremov <yegorslists at googlemail.com>

Use autopep8 utility to resolve issues like spaces before brackets
and wrong hanging indentation.

Also treat objects like boolean variables to check whether they are
None or not.
