No, I don't think so. Python has the trick of "peeking into the future" by backporting a feature in a future version to the current version by using the __future__ module.
However I run Python 2.5 and I do not see any mention of function annotations in __future__ module. Python 2.5.1 (r251:54863, Sep 6 2007, 17:27:08) [GCC 4.1.1 20061011 (Red Hat 4.1.1-30)] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> import __future__ >>> dir(__future__) ['CO_FUTURE_ABSOLUTE_IMPORT', 'CO_FUTURE_DIVISION', 'CO_FUTURE_WITH_STATEMENT', 'CO_GENERATOR_ALLOWED', 'CO_NESTED', '_Feature', '__all__', '__builtins__', '__doc__', '__file__', '__name__', 'absolute_import', 'all_feature_names', 'division', 'generators', 'nested_scopes', 'with_statement'] >>> However, this should be part of Python 2.6. But why bother ? Best thing to do is check out the Python 3.0 trunk, and you can build it and get to know this and other Py3k tricks in a matter of minutes. Use the following svn URL for Py3k. http://svn.python.org/projects/python/branches/py3k HTH. --Anand On Thu, Apr 3, 2008 at 4:34 PM, Heshan Suriyaarachchi <[EMAIL PROTECTED]> wrote: > > > Hi Anand, > This is what I exactly mean.
