Upgrade to Python3

[e1mo]

Argüman still requires Python 2.7 which is deprecated since years. Are there any plans to move forwards to Python 3? pip install displays the warning:

DEPRECATION: Python 2.7 reached the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 is no longer maintained. pip 21.0 will drop support for Python 2.7 in January 2021.
