Changing return of type(obj)
Hello, I am attempting to fully-simulate an 'int' object with a custom object type. It is part of a library I am creating for python futures and promises. Is there anyway such that type(my_object) can return ? Or for that matter, any other primitive? I do not care how dirty the solution might possibly be; Could there be a way through the C API? Though I predict it will cause a mess with the interpreter. Thanks, Ken Elkabany -- http://mail.python.org/mailman/listinfo/python-list
Re: Changing return of type(obj)
I would simply subclass 'int', but this object needs to be general enough to pretend to be an 'int', 'NoneType', 'str', etc... A long shot: Can I change the base class on an instance by instance basis depending on the need? Well, now I can imagine having a class factory that will spawn for me the class that inherits the correct base type. Any other solutions? Thanks Chris.

Rules governing a post about a commercial product
Hello, I am hoping to get feedback for a new, commercial platform that targets the python programming language and its users. The product is currently in a closed-beta and will be free for at least a couple months. After reviewing the only rules I could find (http://www.python.org/community/lists/), I wanted to ask one last time to make sure that such a post would be appropriate. Thanks, Ken -- http://mail.python.org/mailman/listinfo/python-list

Request for Beta Testers
Hello, My company is seeking beta testers for a new cloud-computing platform that is built for the Python programming language. The platform allows Python developers to leverage the computational power of a cluster of servers with only a couple lines of code. If you have a need for distributed computing, or just want to try out some cutting-edge technology, please reply. We'll be letting the first 30 respondents into our closed beta. Common use cases for our platform: * Crawling the web * Manipulating images and videos * Creating charts and graphs * Statistical/Mathematical analysis of data sets * Real-time data processing Best, Ken Elkabany -- http://mail.python.org/mailman/listinfo/python-list

However, in your control panel, you can upload a tarball or synchronize an svn repository that contains your extension's code and we'll automatically compile/install it on our systems. 2) We are currently working on support for python 3.x (we've had requests from a fair number of users), and plan to release a compatible client library in a couple of weeks.
