There exist static analysis tools for Python, but compile time checks tend to be diametrically opposed to the run-time binding philosophy that Python embraces. It's possible to wrap the standard Python interpreter with a static analysis tool to enforce some "use strict"-like constraints, but we don't see any widespread adoption of such a...
I'm behind a router, I need a simple command to discover my public ip (instead of googling what's my ip and clicking one the results) Are there any standard protocols for this? I've heard about STUN but I don't know how can I use it? P.S. I'm planning on writing a short python script to do it ...

I'm looking for a command line tool or some sort of python library (that I can then wrap), so that I can calculate dates that are specified like "last thursday of the month". i.e. I want to let people enter human friendly text like that above and it should be able to calculate all the dates for any month/year/whatever that fulfil that. ...
I have to render a very big image (>50.000² pixel) with cairo. To do this without running out of memory I render parts of the image (<1.000² pixel) one after another and merge them together later. Create 1000x1000 Surface Translate to position of the current part Draw image (calling the drawing instructions using pycairo) Render/Save i...
Hi guys, I`m currently studying C++ and want to learn another language. For work I use C# + ASP (just started learning it, actually), but I want something "less Microsoft" and powerful. I have heard Python is a popular and powerful language, not so complicated as C++. But many people mentioned it was hard for them to get back to C++/Java...
How do I detect an error when compiling a directory of python files using compile_dir? Currently I get something on stderr, but no way to detect it in my app. py_compile.compile() takes a 'doraise' argument, but nothing here. Or is there a better way to do this from a python script? Edit: I fixed it with os.walk and calling py_compil...
Lets say I have the following Django model: class StandardLabel(models.Model): id = models.AutoField(primary_key=True) label = models.CharField(max_length=255) abbreviation = models.CharField(max_length=255) Each label has an ID number, the label text, and an abbreviation. Now, I want to have these labels translatable into...
I have been playing with this a while, and just cannot see an obvious solution. I want to remove the recursion from the XinY_Go function. def XinY_Go(x,y,index,slots): if (y - index) == 1: slots[index] = x print slots slots[index] = 0 return for i in range(x+1): slots[index] = x-i XinY_Go(x-(x-i...
I don't have much experience with tcsh, but I'm interested in learning. I've been having issues getting Python to see PYTHONPATH. I can echo $PYTHONPATH, and it is correct, but when I start up Python, my paths do not show up in sys.path. Any ideas? EDIT: [dmcdonal@tg-steele ~]$ echo $PYTHONPATH /home/ba01/u116/dmcdonal/PyCogent-v1.1 >...
I downloaded a package installer for Python 2.6.1, but when I use the python command in terminal (bash) Apple's shipped 2.3.5 version loads up. How can I get 2.6.1 to load up instead? ...
Edit: Since it appears that there's either no solution, or I'm doing something so non-standard that nobody knows - I'll revise my question to also ask: What is the best way to accomplish logging when a python app is making a lot of system calls? My app has two modes. In interactive mode, I want all output to go to the screen as well as...
Is there an existing implementation of an iterative version of deepcopy for Python 2.5.2? The deepcopy method available from the copy module is recursive and fails on large trees. I am not in a position where we can safely increase the stack limit at runtime. EDIT I did track this down: http://code.activestate.com/recipes/302535/ I h...
I need to render the page differently if it's acessed by an iphone/ipod touch. I suppose the information is in the request object, but what would be the syntax? ...
I have some data that I would like to gzip, uuencode and then print to standard out. What I basically have is: compressor = Popen("gzip", stdin = subprocess.PIPE, stdout = subprocess.PIPE) encoder = Popen(["uuencode", "dummy"], stdin = compressor.stdout) The way I feed data to the compressor is through compressor.stdin.write(stuff...
Is there such a thing as a small, self-contained library that will render an equation written in a text-based format (e.g. LaTeX or MathML) to an image (either vector or raster)? It would be preferable if it's in Python or Python-friendly. (One possibility that I've found: Matplotlib has Python code to parse and display LaTeX equation...
