Python data/file Crc
I am wanting to generate and store a CRC (or similar) value for a given list of files which can be used as a comparison at a later point. Writing a function to do this is simple enough, but is there a more standard way to do it within the Python libs? The value generated does not need to be of any particular standard. ...
Can I detect if my code is running on cPython or Jython?
I'm working on a small django project that will be deployed in a servlet container later. But development is much faster if I work with cPython instead of Jython. So what I want to do is test if my code is running on cPython or Jython in my settiings.py so I can tell it to use the appropriate db driver (postgresql_psycopg2 or doj.backend...
How to match search strings to content in python
Usually when we search, we have a list of stories, we provide a search string, and expect back a list of results where the given search strings matches the story. What i am looking to do, is the opposite. Give a list of search strings, and one story and find out which search strings match to that story. Now this could be done with re b...
Upload a potentially huge textfile to a plain WSGI-server in Python

Combining module files in Python
Is there a way to put together Python files, akin to JAR in Java? I need a way of packaging set of Python classes and functions, but unlike a standard module, I'd like it to be in one file. ...
Scrolling QGraphicsView programmatically
I've want to implement a scroll/pan-feature on a QGraphicsView in my (Py)Qt application. It's supposed to work like this: The user presses the middle mouse button, and the view scrolls as the user moves the mouse (this is quite a common feature). I tried using the scroll() method inherited from QWidget. However, this somehow moves the vi...
Twisted sometimes throws (seemingly incomplete) 'maximum recursion depth exceeded' RuntimeError

Lengthy single line strings in Python without going over maximum line length

Python tell when an ftp transfer sits on completion
I have to download some files from an FTP server. Seems prosaic enough. However, the way this server behaves is if the file is very large, the connection will just hang when the download ostensibly completes. How can I handle this gracefully using ftplib in python? Sample python code: from ftplib import FTP ... ftp = FTP(host) ftp.l...
Pythonic way to get some rows of a matrix
I was thinking about a code that I wrote a few years ago in Python, at some point it had to get just some elements, by index, of a list of lists. I remember I did something like this: def getRows(m, row_indices): tmp = [] for i in row_indices: tmp.append(m[i]) return tmp Now that I've learnt a little bit more sinc...
How to exclude U+2028 from line separators in Python when reading file?
I have a file in UTF-8, where some lines contain the U+2028 Line Separator character (http://www.fileformat.info/info/unicode/char/2028/index.htm). I don't want it to be treated as a line break when I read lines from the file. Is there a way to exclude it from separators when I iterate over the file or use readlines()? (Besides reading t...

So the situation I have is that I have loaded more than one class that I've made that subclasses from asynchat, but I only want one of them to run.
