Yes, but not to the point it's required to make a massive distinction.
'python myfile.py' will work whatever... This isn't meant to be
'shell' scripting / system administration documentation :)

I've found the average Windows user (even Uni. students studying
programming) are somewhat amazed at the black window with white text
that pops up when they run cmd.exe. My favourite comment thus far is,

Sorry you've had bad experiences. However, I would take a leap that
someone has used system/os specific calls (which are mostly un-
necessary) and that at least they've made an effort to port to
Windows. How many projects do you see authors porting from Win to
[This could be construed as a slight rant, but oh well...]

Libraries are moving towards the 3.* series. The development team have
provided tools to assist in migrating, but yes, it's not going to be a
smooth ride. I think the Python development team, and the timelines
planned, are brilliant - take for instance the Boost libraries, of
which some are only making it into the C++200X or whatever now.

My most used tools for Excel (as you mention it) are listed on
www.python-excel.org where John Machin has done a brilliant job of a
platform independent library for reading content from excel
spreadsheets [check out xlwt (for writing) and xlutils (by Chris
Withers for convenience functions)].

Oh the memories! The fun of programming another one, and popping up
messages such as: "Are you making a phone call yet?", "You have a
virus, call your doctor" etc... etc...
Can't say I'm sad it's gone though :)
