[Tutor] request for comments regarding my function

Hello all, I wrote a function to organize a list of sorted objects ( django blog entries ); each object has a Python datetime attribute ( called pub_date ). I am posting a message to the tutor mailing list to get feedback regarding better ways to accomplish the same task. I have a feeling I could u

[Tutor] Moving a Shelf Between Linux and Mac OS X

Greetings, I recently started learning Python and I have written a script that uses a shelf on Mac OS X using Python 2.6. I recently attempted to move the directory over to my Linux system, which also has Python 2.6 installed, and run the script there. The script works fine, but the shelf does n

Ken, Two recommendations. 1) Komodo Edit 5. Free edition available from Activestate. www.activestate,com 2) Wing IDE 101 Free Edition from www.wingware.com my favorite of the freely available IDE's. Good luck, Robert On Sat, 2009-10-24 at 13:57 -0400, Ken G. wrote: > I ju

Isn't it better to use if __debug__: I thought such an if statement always evaluated to False when the python program was run in OPTIMIZED (-o) mode? Cheers!! Albert-Jan ~~ Before you criticize someone, walk a mile in their sho

This is what I have so far, import struct EncryptString="313B372C2E2C63362E2128" XorKey="41424344" key = struct.unpack("d", XorKey) num_ints = len(EncryptString)/11 data = struct.unpack("%dd"% num_ints,EncryptString) The above code generates an error the my string must be a string length of 16

"Tom Green" wrote wondering if there was someway in Python to indicate that the string is a string of HEX values similar to Perl's pack. You need to be very careful in your terminology here. Is it "a string of hex values" ie a string representation of a hex value or is it a string of bytes
