  • 64-bit integers in Cython

    - by Homayoon
    I'm trying to interface a C++ library (pHash) with Python using Cython, but I have trouble with some of the types. The library functions use "unsigned long long" and I can't find a way to declare variables and parameters with this type. I searched for a list of the types that I can use with cdef but I found nothing. Can anyone point me to such a list (if it exists) or otherwise suggest a way to use 64 bit types in Cython? Thanks.

  • Assigning IDs to instances of a class (Pythonic)

    - by mellort
    I want to have each instance of some class have a unique integer identifier based on the order that I create them, starting with (say) 0. In Java, I could do this with a static class variable. I know I can emulate the same sort of behavior with Python, but what would be the most 'Pythonic' way to do this? Thanks

  • Getting started with C++ ( the paradigm shift from Python )

    - by orokusaki
    I want to learn C++ so that i can develop C++ Python modules for server-related stuff. I'm a purely dynamic languages developer (Python, PHP, Ruby, etc). I want to learn a fast language, and if I'm going to do this, I'd rather learn a really fast language like C++. Before I even get started though, I understand that suddenly working with static types, a different syntax, and compiling code will be quite the paradigm shift. Is there any advice that a C++ dev who also has dynamic languages experience can give me to me to help me make that shift faster?

  • How do "and" and "or" work when combined in one statement?

    - by orokusaki
    For some reason this function confused me: def protocol(port): return port == "443" and "https://" or "http://" Can somebody explain the order of what's happening behind the scenes to make this work the way it does. I understood it as this until I tried it: Either A) def protocol(port): if port == "443": if bool("https://"): return True elif bool("http://"): return True return False Or B) def protocol(port): if port == "443": return True + "https://" else: return True + "http://" Is this some sort of special case in Python, or am I completely misunderstanding how statements work?

  • How do I unit test the methods in a method object?

    - by Sancho
    I've performed the "Replace Method with Method Object" refactoring described by Beck. Now, I have a class with a "run()" method and a bunch of member functions that decompose the computation into smaller units. How do I test those member functions? My first idea is that my unit tests be basically copies of the "run()" method (with different initializations), but with assertions between each call to the member functions to check the state of the computation. (I'm using Python and the unittest module.)

Thank you. see also this question: Urllib2 raises 403 error while the same request in curl works fine

  • All non-prime factorings

    - by Tony Veijalainen
    Let's say we have numbers factors, for example 1260: >>> factors(1260) [2, 2, 3, 3, 5, 7] Which would be best way to do in Python combinations with every subproduct possible from these numbers, ie all factorings, not only prime factoring, with sum of factors less than max_sum? If I do combinations from the prime factors, I have to refactor remaining part of the product as I do not know the remaining part not in combination. Example results would be: [4, 3, 3, 5, 7] (one replacement) [3, 6, 14, 5] (two replacements)

  • How should a Gnome applet store its configuration data?

    - by George Edison
    I have a Gnome applet written in Python. In order to save configuration data/settings, it creates a file ~/.appname. However, this prevents multiple instances of the applet from being added to the panel because each cannot have its own settings. How can I store the settings in a way that allows each instance to have its own unique settings? Update: I specifically want to know how to store settings per instance.

  • Open source equivelants to VS / web reference proxy class autogen?

    - by seraphym
    As an ASP.NET developer, I'm used to working with how VS/C# transparently autogens proxy classes for web references (yes, I know, we're spoiled), but now that I'm creating documentation for more than one coding platform I'm trying to discover what the equivelant to that is in any other framework. So is there a similar way to work transparently with web reference proxy classes for say, RoR, PHP, and Python? And if there's nothing integrated, are there tools you recommend to autogen the proxy classes, or do you recommend to roll custom classes?

  • Passing values into regex match function

    - by Tim
    In python (it's a Django filter), I'm doing this: lReturn = re.sub(r'\[usecase:([ \w]+)]', r'EXTEND WITH <a href="/usecase/%s/\1/">\1</a>' % pCurrentProjectName, lReturn) I'd like to use a function instead of a string (so I can check that the usercase is a valid name), so it would change to this: def _match_function(matchobj): lMatch = matchobj.group(1) return "EXTEND WITH <a href='/usecase/%s/%s/'>%s</a>" % (pCurrentProjectName, lMatch, lMatch) lReturn = re.sub(r'\[usecase:([ \w]+)]', _match_function, lReturn) How do I get pCurrentProjectName into the _match_function() function?
