In the following code, there is not just one circle on the screen at any given point in time. I want to fix this to make it so that it looks like there is only one circle, instead of leaving a smudge trail where ever the mouse cursor has been. import pygame,sys from pygame.locals import * pygame.init() screen = pygame.display.set_mode(...

I've noticed differing implementations of the modulus operator in Python and Java. For example, in Python: >>> print -300 % 800 >>> 500 Whereas in Java: System.out.println(-300 % 800); -300 This caught me off guard, since I thought something as basic as modulus was universally interpreted the same way. I'm a fan of Python's interp...
Before the question, the background: I am putting the finishing touches on an API I have written for a Django app utilizing django-piston.

How to specify the axes properly? How to stop the x-axis labels from showing? The first is most important, as I have no idea. I guess one more thing would b...
I'm getting a non-descriptive (or at least I don't know how to interpret in this context) error message when sub-lassing from a Django-Treebeard node and am not sure how to debug.

I am using BeautifulSoup to parse XML: xml = """<person> <first_name>Matt</first_name> </person>""" soup = BeautifulStoneSoup(xml) first_name = soup.find('first_name').string last_name = soup.find('last_name').string But I have a problem when there is no last_name, because it chokes. Sometimes the feed has it, and sometimes it doesn...

I am using Graphviz in Python via pydot. The diagram I am making has many clusters of directed graphs. pydot is putting them next to each other horizontally resulting in an image that is very wide. How can I tell it to output images of a maximum width so that I can scroll vertically instead? ...
I would like to write a Django template tag to which I can pass a variable.
