easiest way to check python version?

[Steve Ferg]

Here is what I use in easygui:
<pre>
#--------------------------------------------------
# check python version and take appropriate action
#--------------------------------------------------
"""
>From the python documentation:

sys.hexversion contains the version number encoded as a single
integer. This is
guaranteed to increase with each version, including proper support for
non-
production releases. For example, to test that the Python interpreter
is at
least version 1.5.2, use:

if sys.hexversion >= 0x010502F0:
    # use some advanced feature
    ...
else:
    # use an alternative implementation or warn the user
    ...
"""
if sys.hexversion >= 0x020600F0: runningPython26 = True
else: runningPython26 = False

if sys.hexversion >= 0x030000F0: runningPython3 = True
else: runningPython3 = False

if runningPython3:
    from tkinter import *
    import tkinter.filedialog as tk_FileDialog
    from io import StringIO
else:
    from Tkinter import *
    import tkFileDialog as tk_FileDialog
    from StringIO import StringIO

</pre>
