Hi Asrarahmed,
There's a few questions in there, and unfortunately I don't have a copy
of your book. But I'll try to answer them, and I'll change the order so
that they build on each other.

Hi Alan,
I think I might be trying to walk before I can crawl; for benefits of
other newbies, I'll summarise lessons learned so far.
Firstly, I spent ages trying to find out why the Python documentation
syntax for Popen, using stdin=PIPE, didn't work:
Traceback (most recent call last):
File ""
There is a good interview on Python 411 last week with the authors of
the book.
http://www.awaretek.com/python/index.html
You can also find a few other shows about gui toolkits in Python. This
is a great resource if you want to learn about Python while you commute.

Hi Kristinn,

When a login name is being created, you can pull a list of existing
login names from file, and run a check to see if it is in the list. If
the new name is in the list, have it kick back a message telling the
user to try another name.
Also, your program could suggest a new user name in such a case,
It means there is no need of entering the data in the dictionary,??
How will I then implement the uniqueness of loginnames???
Thanks for the support.

To keep the information, the simplest solution is simply to save it in
a text file that the program can load into memory when it starts up
again. For sensitive information like passwords, a little extra fuss
is generally merited.
When someone logs in, you can save a value like
