Hi, I have the following problem: I have the class: class Word(object): def __init__(self): self.id = None self.columns = {} def __str__(self): return "(%s, %s)" % (str(self.id), str(self.columns)) self.columns is a dict which will hold (columnName:columnValue) values.

I'm developing a GUI in wxPython which allows a user to generate sequences of colours for some toys I'm building. Part of the program needs to load an MP3 (and potentially other formats further down the line) and display it to the user. That should be sufficient to get started but later I'd like to add features like identifying beats and...
Qt3.3 used to allow for multiple selections in the QTextEdit widget by calling the setSelection() function and specifying a different selection id (selNum) as the last argument in that function. In Qt4, to create a selection, I do it by creating a QTextCursor object and call the setPosition() or movePosition() methods. I have no proble...

This is despite the fact that I've added the path to django_evolution to the system path. In fact right after this error I can run python and do an import on django_evolution and ever...

When there are two identical events in the event loop, will wxPython handle both of them, or will it call the handler only once for them both? I mean, in my widget I want to have an event like EVT_NEED_TO_RECALCULATE_X. I want this event to be posted in all kinds of different circumstances that require x to be recalculated. However, eve...

Python language has a well known feature named interactive mode where interpreter can read commands directly from tty. I tipically use this mode to test if a given module is in the classpath or to play around and test some snippets. Do you know any other programming languages that has Interactive Mode? If you can, give the name of the...

When there are too much widgets to fit in the window, I want to use a scrollbar, so I put tix.ScrolledWindow inside that Frame and add my widgets to this ScrolledWindow instead. The problem is that when using the grid() geometry manager, the scrollbar ap...
Hi, I am writing a script to automate running a particular model. When the model fails, it waits for a user input (Enter key). I can detect when the model has failed, but I am not able to use python (on linux) to simulate a key press event. Windows has the SendKeys library to do this but I was wondering if there is a similar library for...
I know this question may well be the silliest question you've heard today, but to me it is a big question at this stage of my programming learning. Why is the second empty line needed in this Python code? What does that line do? print 'Content-Type: text/plain' print '' print 'Hello, world!' ...
