hi

is there something analogous to sys.platform that lets you get the version of python you're using? sorry if the question is too see-spot-run. thanks if you can help

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.

You want this??

Check out sys.version and sys.version_info - are they what you're after?

Since everyone else has answered the question you asked, let me answer
the question I think you might have wanted to ask instead.

If what you're trying to determine is simply whether you're running
under Python 2 or 3, then the six package has booleans for six.PY2 and
six.PY3, so you can say things like:

  if six.PY2:
    def my_fn():
      ...
  else:
    def my_fn():
      ...

Note that checking compatibility this way (calling Python 2 "the weird
one") rather than "if six.PY3" will keep your code compatible in the
future as well.

Bringing in an entire extra package just for one boolean seems
excessive, but if you're actually making that check it's because you've
got a bunch of 2/3 compatibility crap you're having to work out; six
will help will all of that too.
