Subject: Re: [Tarantool-patches] [PATCH v1] Support to run tests with Python 3
Date: Tue, 1 Dec 2020 20:03:27 +0300	[thread overview]
Message-ID: <f1e42524-2ad2-a71e-abc2-0239cf560a2b@tarantool.org> (raw)
In-Reply-To: <cd02c9942f4a62e106b95de4538383a46b96cff6.1605902329.git.sergeyb@tarantool.org>

Hi! Thank you for the patch.
See some comments bellow:

1) According to 
https://github.com/tarantool/tarantool/wiki/Code-review-procedure#commit-message
the title of commit message might look like:"tests:..."

2) According to PEP8, mixing using double quotes and quotes in a project
looks inconsistent (one must be selected). I understand that this is not
the purpose of your patch, but it can be cleaned up as well.

3) In addition to the previous one, I suggest choosing one of the
"format" or "%".
