Ok, but please check *what* are the arguments to Popen. If cmd is a *list*

to use the sequence protocol,
starting at 0; that is, tries to get msg[0]. Message objects support the
mapping protocol, and msg[0] tries to find a *header* 0, converting the
name 0 to lowercase, and fails miserably.
Try with:
for msg in mbox:
print msg
or read the MaildirMessage (and Message) docs to see the ways you can
handle it.

ts contents
and properties. Modifying an object is not the same as rebinding its name:
x = [1,2,3]
y = x
x[1] = 4
print x # [1, 4, 3]
print y # [1, 4, 3]
x = [1,2,3]
y = x
x = [1,4,3]
print x # [1, 4, 3]
print y # [1, 2, 3]
You can test is two names refer to the same object using the is operator:
x is y. You will get True in the first case and False in the second case.

See http://effbot.org/zone/import-confusion.htm
Try to move the circular references later in the code (maybe inside a
function, when it is required), or much better, refactor it so there is no
circularity.

I think you will like it in the near future. But for someone coming from
the microcontroller world, used to think closely in terms of the
implementation, this may be a big paradigm shift.

message should mean iterating over its headers... Anyway,
if you want to iterate over all the message headers, the simplest way is
using msg.keys()

3) shutil.copyfile copies ONE FILE at a time.
4) use glob.glob to find the desired set of files to be copied; and
perhaps you'll find copy2 more convenient.

40.7 msec per loop
(Generating less values shows larger differences - anyway they're not
terrific)
So, as always, one should measure in each specific case if optimization is
worth the pain - and if csv files are involved I'd say the critical points
are elsewhere, not on how one creates the list of rows.

"strings" are "strings of bytes" in Python. (If you are mostly concerned
with characters, use unicode objects).
