"SyntaxError: invalid syntax" when running with python3

[narqo]

I see the following error, after installing yandex-tank under python3

> python --version
Python 3.6.5
> pip install --user https://api.github.com/repos/yandex/yandex-tank/tarball/master
···
> yandex-tank --help
···
key=lambda (k, v): (-1 * v[self.cases_sort_by], k))
^
SyntaxError: invalid syntax

Everything works as expected with python2.7, but python2's support ends by the end of 2019.

Thank you for the issue! We are working on migration, it would be introduced soon.

@narqo py3 is not supported in master, please try python3 branch instead
