Hi all, I do apologise for this,
This was an email that has nothing to do with Python or the tutor
list, so my apologies to all. Somehow I managed to send it to the
wrong recepient.
(And my thanks to Bob for being brave enough to attempt to answer what
would be a hopelessly vague question. :-) )

The first step in the calculation is to split the input into two strings: the

Hi Doug,
Best tip ever is your_python_dir\tools\scripts\redemo.py
Interactive regexes. :)

Hi,
You can use expanduser() from os.path for this:
import os.path
homedir = os.path.expanduser('~user1')
file_to_open = os.path.join(homedir, '.myapp.conf')
f = open(file_to_open, 'r')

use os.path.expanduser(path)

os.getenv('HOME') will return the user's home directory as long as that
environment variable is set.
you can also use the pwd module:
>>> pwd.getpwnam('mtw')
('mtw', 'x', 1000, 1000, ',,,', '/home/mtw', '/bin/bash')

I want to read a configuration file from a small python app (user preferences).
The ".myapp.conf" is in the home folder of the user.

obviously I won't know the home user folder name then I wanted to use:

There are some tricks you can pull but the object is actually instantiated
before the init gets called. Really init is for initialisation of the
instance,
it's not a true constructor.

Thank you Michael, Danny and Alan for your suggestions.
I've included below my summary of the three very different
suggestions, my brief analysis of them, and my conclusion.
Anyone is free and welcome to comment!

Even though I am still new to python, I've recently had an insight as
to what makes OOP different from procedural programming.
Let's take perl for example. A variable in perl is like a bowl. It's an
empty vessel you can put things in. You can change the contents of
the bowl, you can empty the b

Hi,

I tried:
