Does there exist a native Python implementation of the Jenkins hash algorithm(s)? I need a hash algorithm that takes an arbitrary string and turns it into an 32-bit integer. For a given string, it must guarantee to return the same integer across platforms. I have looked at the ELF hash algorithm, of which I have found a Python implemen...
Hi, I am comparing 2 txt files that are ls -R of the etc directory in a linux system. I compared the 2 files using difflib.differ and got this list as my result (i put the dots to keep the list short in here): result = [' etc:\n', ' ArchiveSEL\n', ' HOSTNAME\n', ' RMCPUser\n', ..., ' qcleaner\n', '+ extraFile\n', ' rc.d\n', '+ extra...

I'm completely new to Python and while trying various random bits and pieces I've struck upon a problem that I believe I've "solved", but the code doesn't feel right - I strongly suspect there is going to be a better way to get the desired result.
