[Tutor] The Order of Imports and install order of modules and other matters (XP vs W7, ...)

[Wayne Watson]

There seems to be something of a general consensus in ordering import 
statements. Something like standard library imports first. When using 
tools like matlablib or tkinter (maybe), must one keep an order among 
the relevant imports?

Related to this is the order in which modules are installed. Does it 
make a difference?

Finally, I'm in the process of moving Python code from XP to Win7. I 
just grabbed all the install files I have from XP, and executed them on 
W7. Everything seems to be working as expected, but one strange thing 
happened with scipy. It produced a warning about something like "unable 
to provide key".  I continued anyway. All seems well. Was I supposed to 
use some W7 version of the "XP" files? This is anomaly 1.

OK, this the last one. In both XP and W7, I've found executing a program 
by use of the py file (not IDLE. Is there a name for this method?) using 
numpy that  see early on in the DOS-like window (is there name for it 
too?) it's complaining (alerting me) about deprecations and some use of 
a numpy test. What's that about? This is anomaly 2.
