Dear Tutors,
whenever I make use of the help() function, I have a good chance of
getting an error. I have not yet understood this tool very well.

I am trying to teach myself Python (using John Zelle's book "Python

Hello,
I'm working on an application in which I need the main loop to call the
same method on a number of objects. I came up with this solution that
seem to work, but I was wondering if there is a better / more pythonic
solution to the problem.

Try this. I embedded the test data to simplify testing:
data = """48 ALA H = 8.33 N = 120.77 CA = 55.18 HA = 4.12 C = 181.50
104 ALA H
I am not an expert, but if I got you correctly, what you want to achieve
is a "singleton": http://en.wikipedia.org/wiki/Singleton_pattern if you
watch at the sample implementation, there is a Python example too.

Hey all,
I have an app that runs in a GUI written in pygtk. It spawns several
threads, and runs all the time.
It is mission critical that we can never have two instances of this

By default django looks for a file called *tests.py*(plural) and not *

You are returning the values to variables in the main function.
