Based on a few 3rd party tutorials I found, I've extended the User class and it seems to work OK: from...

I'm working from inside an ipython shell and often need to reload the script files that contain my functions-under-construction. Inside my main.py I have: def myreload(): execfile("main.py") execfile("otherfile.py") Calling myreload() works fine if I have already ran in the same ipython session the execfile commands directly. ...
the only difference that i know between randrange and randint is that andrange([start], stop[, step]) you can use the step and random.randrange(0,1) will not considerate the last item and randint(0,1) return a choice inclusive of the last item so, i can't find a reason for explain why randrange(0,1) doesn't return 0 or 1, why exist rand...
Possible Duplicate: modify a datastream on the fly I need to hijack and modify a datastream. The stream consists of fixed-width commands.

I want to run a django app on a hand-held device. It'll need to run Python (obviously) and will write its data to an SQLite database. Are there any tablets available that will let me do this?

I've read in "Dive into Python 3" that "The readlines() method now returns an iterator, so it is just as efficient as xreadlines() was in Python 2". See here: http://diveintopython3.org/porting-code-to-python-3-with-2to3.html . I'm not sure that it's true because they don't mention it here: http://docs.python.org/release/3.0.1/whatsnew/3...
In Python 2, file objects had an xreadlines() method which returned an iterator that would read the file one line at a time. In Python 3, the xreadlines() method no longer exists, and realines() still returns a list (not an iterator). Does Python 3 has something similar to xreadlines()? I know I can do for line in f: instead of for ...
