Well, this question doesn't match the subject line. So, *two* answers.

To open a web browser from within a python program, you want something like:

import webbrowser
webbrowser.open('www.google.com')

To run a shell command - well, it depends. If you don't care about
reading the output or so on, you can just do:

import os
os.system('ls')

If you want to access the input and/or output streams, or to wait for
the shell command to finish, or anything even remotely complex, look
at the subprocess module.

I think you must have had some other issue. In Python, string literals
can be delimited by either singe or double quotes - the resulting
string is identical. (The difference is that in a single quoted
strung, you can use double quote characters without quoting, and
vice-versa. There's yet more to sting literals that this - raw stings,
triple-quoted strings, unicode strings - see
<http://docs.python.org/ref/strings.html> for details.)

If you don't keep references too them (i.e. by having names that are
bound to them, or by keeping them in collections) then they'll go away
- usually as soon as the last reference to them is gone.

If you do:

import calendar
print calendar.__file__

That will tell you where it is on your system. Works for any module.

Yup. Install however many versions you want. Install the version that
you want to use by default (i.e. the version that gets used when you
double-click on a .py file) *last*.

But anyway, it looks like there's a problem at developeriq's end, so
you'll have to contact them to get it fixed.

The article discusses two ways of doing SOAP; by hand, and using
SOAPpy. Building the SOAP message by hand is part of the first
section, using SOAPpy is the second.

There's also a number of other article in the series:

Best? That's a potentially contensious one. But I can tell you that if
you were to look at either Django or TurboGears you wouldn't be going
too far wrong. (I use Django, but I know that both are good.)

Cheetah's good, but if you go with Django, it has its own which is
pretty good too. (I use both at times.)

Sets, like dictionaries, hold their items in an arbitrary order - see

Python doesn't really *have* variables, as such, so no. What it does
is to create a tuple referring to the objects (or just possibly one
object) referred to by the names 'y' and 'x', then re-binds the
objects from the tuple to the names 'x' and 'y' respectively.

Reset your brain!
