Unable to unpickle a file on Mac that was pickled on Windows
Hello, I've got a simple class that I am pickling(dumping) to a file. On OS X this works fine, and on Windows this works fine. However, while on windows I can load/unpickle the object fine - when windows then pickles this file and saves it back to disk, it becomes unreadable on OS X (although in Windows it still behaves as normal). Th...

Making Python Use Code in My Directory (not that in /usr/...)
I am trying to work on a Python library that is already installed on my (Ubuntu) system. I checked out that library, edited some files, and wrote a small script to test my changes. Even though I put my script in the same folder as that of the library, it seems Python is using the installed version instead (the one in /usr/share/pyshared/...
What's the most pythonic way of normalizing lineends in a string?
Given a text-string of unknown source, how does one best rewrite it to have a known lineend-convention? I usually do: lines = text.splitlines() text = '\n'.join(lines) ... but this doesn't handle "mixed" text-files of utterly confused conventions (Yes, they still exist!). Edit The oneliner of what I'm doing is of course: '\n'.join...

Hi Everyones, I would like to remove one null byte in a string, and sometime replace it with another char.

Replacement for python statvfs?
The python statvfs module is marked as deprecated, but I haven't been able to figure out what new apps are supposed to use if they want to get information about a disk, specifically how to check the capacity and free space of a given path.

Fractal image scaling with Python
I am in a position where relatively low resolution images are provided (via an API, higher resolution images are not available) and high resolution images need to be generated. I've taken a look at PIL and it's just great for about everything... Except scaling up images. It has the common resizing algorithms: Nearest Neighbor Bilinea...
Fastest way to search 1GB+ a string of data for the first occurence of a pattern in Python.
There's a 1 Gigabyte string of arbitrary data which you can assume to be equivalent to something like: 1_gb_string=os.urandom(1*gigabyte) We will be searching this string, 1_gb_string, for an infinite number of fixed width, 1 kilobyte patterns, 1_kb_pattern. Every time we search the pattern will be different. So caching opportunities ...
