Assigning a function to sys.excepthook doesn't work in WSGI

I want to generate an html page with http response status '200 OK' in case of an uncaught exception in my wsgi application, instead of web server's standard '500 Internal Server Error' response for such case. To do so, I've made the following sample code: import sys def application(environ, st

PythonMagick on Windows DLL load failed

Logging with Custom Levels not working

Greetings, I've been setting up a custom logging for a project here and got some great examples of code from stackoverflow. The only problem I'm having is that no matter what I set the log level too all the messages print out... Verbosity Level set to: 55 [PVERBOSE] Performance Verbose Leve

Issues pip-installing pywin32

(Before I begin, I want to make it clear that I can still go poke around on SourceForge and grab the appropriate installer [1], and that does work. But if I'm going to tell someone else how to set up this program, I'd much rather be able to recommend pip.) On a fresh Python 3.4 running on Windows

Dependencies from git aren't being installed? (setuptools, pip)

I'm sure I've just misconfigured my setup.py, requirements.txt and/or project structure, but I've tried: * install_requires * requirements.txt * install_requires + dependency_links With (for install_requires): * bettertutors_sql_models==dev * bettertutors_sql_models For requirements.txt, depende

Re: python implementation of a new integer encoding algorithm.

Hi Jan. I'm an old fart. In the late 1970s, when I started programming these things, and memory was non-existant, we came up with all sorts of data compression algorithms which were absolutely necessary to get any work done whatsoever. Should you ever need an assembler programmer for quick and d
