Lots of programming languages already have the compound statements +=, -=, /=, etc. A relatively new style of programming is to "chain" method calls onto each other, e.g. in Linq, JQuery and Django's ORM. I sometimes, more often than I'd like, find the need to do this in Django: # Get all items whose description beginning with A items ...
I'm implementing a Python ontology class that uses a database backend to store and query the ontology. The database schema is fixed (specified in advance), but I don't know what type of database engine is being used. However, I can rely on the fact that the Python interface of the database engine uses the Python DB-API 2.0 (PEP 249). A s...
I have a dynamically created table, that has N rows and M QTableWidgetItems (that are only used as checkboxes) per row - I need to run code that knows the row and the column whenever a checkbox is checked or unchecked. My CheckBox subclass looks like: class CheckBox(QTableWidgetItem): def __init__(self): QTableWidgetItem.__...
I want to write a web-based code generator for a Python crawler. Its aim is to automatically generate code so a developer doesn't need to write it, but I've run into this problem: in one of my project's webpages, there are some checkboxes, buttons, etc. Each of them generates some Python code and writes it to a common textarea. However, ...
I need to write model data (CharFields only) to an XML file to contain the data for a flash file. I am new to this, and the process is a little unclear to me for doing this in django. I am creating an xml file, and then writing the text data to the file (as is done with the csv module, but to xml). A very simplified xml file should re...
This problem sounds simple at first glance, but turns out to be a lot more complicated than it seems. It's got me stumped for the moment. There are 52c5 = 2,598,960 ways to choose 5 cards from a 52 card deck. However, since suits are interchangeable in poker, many of these are equivalent - the hand 2H 2C 3H 3S 4D is equivalent to 2D 2S ...

Hi am going through the docs of GAE and needed a small clarification. If I have my db model something like this:- class Phone(Model): phone_name = db.StringProperty() r = Phone(Nokia, key_name='first') r.put() Now if I have to retrieve this entity but I dont know the key, can I construct the key like this: k=db.Key('Phone','first'...
Suppose I have the following code in a Python unit test: aw = aps.Request("nv1") aw2 = aps.Request("nv2", aw) Is there an easy way to assert that a particular method (in my case aw.Clear()) was called during the second line of the test? e.g. is there something like this: #pseudocode: assertMethodIsCalled(aw.Clear, lambda: aps.Request...
I have a python package called zypp. It is generated via swig and the rpm package (called python-zypp) puts it in: rpm -ql python-zypp /usr/lib64/python2.6/site-packages/_zypp.so /usr/lib64/python2.6/site-packages/zypp.py Now, I have a different project which provides an additional sets of APIs. Pure python. Plus some scripts. The la...
I'm writing unit tests in Python for the first time, for a Django app. I've struck a problem. In order to test a particular piece of functionality, I need to change the value of one of the app's settings. Here's my first attempt: def test_in_list(self): mango.settings.META_LISTS = ('tags',) tags = Document(filepath).meta['tags']...
I am trying to use Python (through Django framework) to make a Linux command line call and have tried both os.system and os.open but for both of these it seems that the Python script hangs after making the command line call as the call is for instantiating a server (so it never "finishes" as its meant to be long-running). I know for doin...
