Manipulating sys.path
Hi all, I want to manipulate sys.path outside of PYTHONPATH (environment) and sys.path.append() (programmatically). A bit of background: We're maintaining a small application that includes a couple of Python scripts. Over time, a decent amount of code has been forked into modules, so the overall file syste... 9 Jul 2008 06:30

What do you think? What works? What doesn't? I'll try to answer feedback on python-list or o... 11 Jul 2008 14:03

Returning the positions of a list that are non-zero
I have a very large list of integers representing data needed for a histogram that I'm going to plot using pylab. However, most of these values (85%-95%) are zero and I would like to remove them to reduce the amount of memory I'm using and save time when it comes to plotting the data. To do this, I'm trying to find... 9 Jul 2008 11:38

a simple 'for' question
Hi fans, I want to use a 'for' iteration to manipulate files in a set of folders, something like: folders= ['1A28','1A6W','56Y7'] for x in folders: print x # print the current folder f = open('my/path/way/x/my_file.txt', 'r') ... where 'x' in the pathway should iterate over '1A28','1A6W',... 10 Jul 2008 12:22

I also know that ODBC is supported under Linux (I don't know anything of Linux), but how can I get all ODBC databases in ... 8 Jul 2008 19:16

how to remove oldest files up to a limit efficiently
I need to mantain a filesystem where I'll keep only the most recently used (MRU) files; least recently used ones (LRU) have to be removed to leave space for newer ones. The filesystem in question is a clustered fs (glusterfs) which is very slow on "find" operations. To add complexity there are more than 10^6 files ... 9 Jul 2008 18:52

(silly?) speed comparisons
Out of curiosity I decided to make some speed comparisons of the same algorithm in Python and C++. Moving slices of lists of strings around seemed like a good test case. Python code: def move_slice(list_arg, start, stop, dest): frag = list_arg[start:stop] if dest > stop: idx = dest - (stop - start) e... 9 Jul 2008 11:38
