Nice work! But I have a question...

Why do you say 10e-20 instead of 1e-19?

I'm just curious which formula for pi is given here: ?
def pi():
"""Compute Pi to the current precision.

Hi,
I have found some inaccuracy in the Python Library Reference
6.29.5.4 TimedRotatingFileHandler
(http://docs.python.org/lib/node349.html)
1)
it is not really obvious from the documentation the "when" value has
to be in the format "w0", "w1" ... "w6" if "Type of interval" is
defined as a "week

And honestly, it should work all of the time. If it doesn't, file a bug
report. I can't stand it when that doesn't work. Some of us don't do
all of our work with a browser handy, and a net

The basic syntax is just the name, with parameters in brakcets:
object.method(par1, par2, ...)
This is explained in the documentation, of course.
>how do I find
Just getting to grips with Python, a great language BUT
With something like Java I can find the syntax of a method call with no
problems, how do I do the same with Python?
For example, using MySQLdb or SGMLParser I can see what the available
methods are with dir, but how do I find out what paramet
