How do I check what version of Python is running my script?

Question

How can I check what version of the Python Interpreter is interpreting my script?

Answer 1

I like sys.hexversion for stuff like this.

http://docs.python.org/library/sys.html#sys.hexversion

>>> import sys
>>> sys.hexversion
33883376
>>> '%x' % sys.hexversion
'20504f0'
>>> sys.hexversion < 0x02060000
True
