well, you may already know that "append" is a method that belongs to
lists:

>>> dir([])
['append', 'count', 'extend', 'index', 'insert', 'pop', 'remove', 
'reverse', 'sort']
>>>

So, you probably want to find a list in the sys module:

>>> import sys
>>> for item in dir(sys):
...     if type(getattr(sys, item)) == type([]):
...         print item
...
argv
path
>>>


Well... this is a tough choice. check the docs:

>>> print sys.__doc__
[lots of good reading snipped]
argv -- command line arguments; argv[0] is the script pathname if known
path -- module search path; path[0] is the script directory, else ''
[more good stuff snipped]


so... you might try:

>>> import sys
>>> sys.path.append('c:/mysqldui/piddle')


I guess my point is that python itself has lots of ways to tell you
about python. Personally, when I have questions, I often find myself
trying things out in the interpreter before I even reach for the
manual.

Heh.. This is kinda funny. :) First, you might want to think about
getting a better text editor... One that does syntax highlighting and
whatnot might come in handy.

But.. all you have to do is go into windows explorer, find that
file and either:

   click on it and hit F2

or:

   right-click and select "rename"
