I've written some scripts, which run either only with Version 2.x or some only with Version 3.x of Python.
How can I detect inside the script, if it's started with fitting Python Version?
Is there a command like:
major, minor = getPythonVersion()

You can use the six library (https://pythonhosted.org/six/) to make it easier to write code that works on both versions.
(It includes two booleans six.PY2
and six.PY3
which indicate whether the code is running in Python 2 or Python 3)
Also in Python 2.6 and 2.7, you can use
from __future__ import (print_function, unicode_literals, division)
__metaclass__ = type
to enable some of the Python 3 behaviour in a way that works on both 2 and 3.
sys.version_info
provides the version of the used Python interpreter.Python 2
Python 3
