  • Is it possible to make an OS in python?

    - by None
    I was just wondering if it was possible to make an operating system in python. Nothing fancy. Maybe not even a "real" operating system with a kernel and all. Just a python program that is run when someone inserts the disc containing it that will make a fullscreen display on top of the installed os.

  • How to compile OpenGL with a python C++ extension using distutils on Mac OSX?

    - by Matthew Mitchell
    When I try it I get: ImportError: dlopen(/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/site-packages/cscalelib.so, 2): Symbol not found: _glBindFramebufferEXT Referenced from: /Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/site-packages/cscalelib.so Expected in: dynamic lookup I've tried all sort of things in the setup.py file. What do I actually need to put in it to link to OpenGL properly? My code compiles fine so there's no point putting that on there.

  • In what situation should the built-in 'operator' module be used in python?

    - by apphacker
    I'm speaking of this module: http://docs.python.org/library/operator.html From the article: The operator module exports a set of functions implemented in C corresponding to the intrinsic operators of Python. For example, operator.add(x, y) is equivalent to the expression x+y. The function names are those used for special class methods; variants without leading and trailing __ are also provided for convenience. I'm not sure I understand the benefit or purpose of this module.

  • Using Ruby/Python code in an iPhone OS app?

    - by igul222
    My app needs to use a library which is only available for Python and Ruby. From my understanding, Apple allows Ruby to run on iPhone as long as users can't execute arbitrary code (Rhomobile uses Ruby). How can I bundle Ruby/Python with my app, call a function from my Obj-C code, and get the result (a string) back in C or Obj-C format?

  • Am I right in thinking there is no way to put an if statement and an else statement on line in Python?

    - by Louise
    Am I right in thinking I can't put an if-statement and the corresponding else-statement on one line in Python? NB: variable = value1 if condition else value2 is NOT two statements. It's one statement which can take the value of one of two expressions. I want to do something like if condition a=value else b=value Am I right in thinking this requires a full if-else in Python? Like if condition: a=value else: b=value Thanks, Louise

  • What if I have an API method and a contoller/view method with the same name in RoR?

    - by Chad Johnson
    Suppose I want to be able to view a list of products on my site by going to /product/list. Great. So this uses my 'list' view and outputs some HTML which my web browser will render. But now suppose I want to provide a REST API to my client where they can get a list of their products. So I suppose I'd have them authenticate with oAuth and then they'd call /product/list which would return a JSON array of their products. But like I said earlier, /product/list displays an HTML web page. So, I have a conflict. What is normal practice as far as providing APIs in Rails? Should I have a subdirectory, 'api', in /app/controller, and another 'product' controller? So my client would go to /api/product/list to get a list of their products? I'm a bit new to RoR, so I don't have the best grasp of the REST functionality yet, but hopefully my question makes sense.

  • Learning the Introspection API (used by FxCop)

    - by Anand Patel
    Microsoft's FxCop tool uses the introspection API. This introspection API could be used to develop new code analysis tools. But the introspection api is not documented well. Additionally, I was not able to figure out any blogs which explains this API in breadth and depth of it. The knowledge gained by understanding the API can also be used for writing custom FxCop rules. Does anybody knows about any blog or resources which explains the same?

  • Using Google Weather API with Lat and Lon - how to format?

    - by Paul
    I am wanting to use the Google Weather API - by passing lat and long values. However it seems Google is needing these formatted differently to the values I have stored. i.e. For the town of McTavish I have values of 45.5 and -73.583 This works here: http://api.wunderground.com/auto/wui/geo/WXCurrentObXML/index.xml?query=45.5,-73.583 But when I use Google it does not: See: www.google.com/ig/api?weather=,,,45.5,-73.583 Any help appreciated. I would prefer to use the Google Data.

  • Facebook Api - Local development, Testserver, Liveserver ... How?

    - by Thijs Kaspers
    I'm working on a new website that uses the Facebook API for users to login and several implementations of the graph Api. My workflow usually is: Development on localhost Development using MAMP/XAMPP or similar software Push to server - testing domain A team of people can test the changes for a few days to see if everything works as planned. Push to server - live domain Changes are live for public Facebook uses the site URL in the appsettings and for security reasons, they will only redirect to that url... Problem is.. I have localhost and 2 different domains. How can I make this work? Ofcourse I could edit the hostsfile, but that only fixes it for localhost.. Still no solution for the testdomain. Please tell me this is somehow possible! I'm getting more and more depressed with the Facebook API.

  • Upload images API on 3rd Party host .. Flickr ?

    - by Enatom
    I am building an Image Sharing feature for my website, where users can upload images and show it off on my website, through their own profile gallery. Except I dont want to physically host the uploaded images. Are there API's that can allow me to descretly save the uploaded images (from the users) to another Host, such as Flickr, Google etc.. I know Flickr has a good API, but could I use it for this? And does the Flickr Upload API only work with authorised users ? becuase I dont want them to upload to their Flickr account, but just host them with 1 big account so to speak thanks.

  • Is there any way to run Python on Android ?

    - by e-satis
    I like the Android platform. Actually, with some friends, we even participate to the ADC with the Spoxt project. But Java is not my favourite language at all. We are working on a S60 version and this platform has a nice Python API. Of course there is nothing official about Python on Android, but since Jython exists, does anybody know a way to let the snake and the robot work together ?

  • What's the scope of a Python variable declared in an if statement?

    - by froadie
    I'm new to Python, so this is probably a simple scoping question. The following code in a Python file (module) is confusing me slightly: if __name__ == '__main__': x = 1 print x In other languages I've worked in, this code would throw an exception, as the x variable is local to the if statement and should not exist outside of it. But this code executes, and prints 1. Can anyone explain this behavior? Are all variables declared in a module global/available to the entire module?

  • efficiently finding the interval with non-zeros in scipy/numpy in Python?

    - by user248237
    suppose I have a python list or a python 1-d array (represented in numpy). assume that there is a contiguous stretch of elements how can I find the start and end coordinates (i.e. indices) of the stretch of non-zeros in this list or array? for example, a = [0, 0, 0, 0, 1, 2, 3, 4] nonzero_coords(a) should return [4, 7]. for: b = [1, 2, 3, 4, 0, 0] nonzero_coords(b) should return [0, 2]. thanks.

  • Why is "int + string" possible in statically-typed C# but not in dynamically-typed Python?

    - by Salvador Dali
    While studying C# I found it really strange, that dynamically typed Python will rise an error in the following code: i = 5 print i + " " whereas statically typed C# will normally proceed the similar code: int i = 5; Console.Write(i + " "); I would expect other way around (in python I would be able to do this without any casting, but C# would require me to cast int to string or string to int). Just to highlight, I am not asking what language is better, I am curious what was the reason behind implementing the language this way.

  • Is it guaranteed that False == 0 and True == 1 in Python?

    - by EOL
    Is it guaranteed that False == 0 and True == 1, in Python? For instance, is it in any way guaranteed that the following code will always produce the same results, whatever the version of Python (existing and in the foreseeable future)? 0 == False # True 1 == True # True ['zero', 'one'][False] # is 'zero' Any reference to the official documentation would be much appreciated! Other comments would be appreciated too… :)

  • Why can't I access the instance.__class__ attribute in Python?

    - by froadie
    I'm new to Python, and I know I must be missing something pretty simple, but why doesn't this very, very simple code work? class myClass: pass testObject = myClass print testObject.__class__ I get the following error: AttributeError: class myClass has no attribute '__class__' Doesn't every object in Python have a __class__ attribute?
