Can I somehow check from inside a Python script if the executing Python engine

I am thinking about a code similar to
if (os.python-majorversion<3)
print hello
else
print (hello)
For this, just use print('hello').
Checkout 'from __future__ import print_function'
check __future__ module for spelling.
Checkout sys.version, sys.hexversion, platform module,
Some import will tell you.
try:
import tkinter as tk
pyversion = 3
except ImportError:
import Tkinter as tk
pyversion = 2
Additional question:
Is there a way to execute a python script with v3 python engine in v2
compatibility mode?
I am thinking about a command parameter like (python.exe is v3.*):
python.exe -execute_as_v2 myscript.py
No.
