The same ‘sys’ module provides many other ways to interrogate the
running Python system <URL:https://docs.python.org/3/library/sys.html>.

For the running version of Python, you want ‘sys.version_info’::

    >>> import sys
    >>> sys.version
    '2.7.11 (default, Jan 11 2016, 21:04:40) \n[GCC 5.3.1 20160101]'
    >>> type(sys.version)
    <type 'str'>

    >>> sys.version_info
    sys.version_info(major=2, minor=7, micro=11, releaselevel='final', serial=0)
    >>> type(sys.version_info)
    <type 'sys.version_info'>
    >>> sys.version_info > (3, 1)
    False
    >>> sys.version_info > (2, 5)
    True

The ‘sys.version’ object is a human-readable string. If you actually
want to do comparisons, use ‘sys.version_info’ for its much more
fine-grained structure.
