I have a scientific data management problem which seems general, but I can't find an existing solution or even a description of it, which I have long puzzled over. I am about to embark on a major rewrite (python) but I thought I'd cast about one last time for existing solutions, so I can scrap my own and get back to the biology, or at l...

I'm new to Python, and I wanted to make sure that I overrode __eq__ and __hash__ correctly, so as not to cause painful errors later: (I'm using Google App Engine.) class Course(db.Model): dept_code = db.StringProperty() number = db.IntegerProperty() title = db.StringProperty() raw_pre_reqs = db.StringProperty(multiline=...
I am trying to write a long string in Python that gets displayed as the help item of an OptParser option. In my source code .py file, I'd like to place newlines so that my code doesn't spend new lines. However, I don't want those newlines to affect how that string is displayed when the code is run. For example, I want to write: pa...

Hi Folks, I'm looking for most fastest/effective way of deleting certain keys in a python dict Here are some options for k in somedict.keys(): if k.startswith("someprefix"): del somedict[k] or dict((k, v) for (k, v) in somedict.iteritems() if not k.startswith('someprefix')) Logically first snippet should be faster o...

I have a QVBoxLayout that I've added a few widgets to, via addWidget(). I need to now delete those widgets, and it seems I need to use removeWidget() (which takes in a widget to be removed) to do that. I thought that calling children() or findChildren(QWidget) on my layout would return a list of the widgets I've added into it; I'm in t...
In Mercurial, many of the extensions wrap their help/syntax string in a call to an underscore function, like so: _('[OPTION] [QUEUE]') This confuses me, because it does not seem necessary (the Writing Extensions instructions don't mention it) and there doesn't seem to be a _ defined in the class, so I'm wondering if this is some spec...

So I have large multi-line string snippets of django template code that should be populated with variables that are also stored ...

Hi all, I'm building Pylons web applications that use a lot of jQuery and AJAX/JSON to make these apps more Web 2.0'ie. I've been looking at the server push technologies and have questions about how to do this with Pylons.
