How should the layout of a Python application look? Currently I have: setup.py application_name/ __main__.py __init__.py views/ controllers/ model/ r...

I have to run a legacy Zope2 website and have some grievance with it. The biggest issue is that, occasionally, it just locks up, running at 100% CPU load and not answering to requests anymore. While the problem isn't reproducible on a regular basis, one page containing 3 dynamic graphs triggers it sometimes, so I suspect some kind of rac...

I am new to Python and would like to know if someone would kindly convert an example of a fairly simple Perl script to Python? The script takes 2 files and outputs only unique lines from the second file by comparing hash keys. It also outputs duplicate lines to a file. I have found that this method of deduping is extremely fast with Pe...
I'm trying to use fancy indexing instead of looping to speed up a function in Numpy. To the best of my knowledge, I've implemented the fancy indexing version correctly. The problem is that the two functions (loop and fancy-indexed) do not return the same result. I'm not sure why. It's worth pointing out that the functions do return the s...
