Oh, and there's more involved in actually printing the headers if you

(That's in the docs for the email module, though it
the $varname format you used above).
Which you choose depends on how you want to work, but I'd recommend
.format() for most things.
Except for your os.system call, where I'd recommend using the subprocess
module instead, in which case you'd do something like this:

Yep. Run 'make test' instead of running them one by one. make test
will run them under regrtest, which has mechanisms for detecting tests
that are expected to or may reasonably fail on a given platform. Then if
you still have errors, report back
e subprocess.Popen instead, that's better).
By the way, when you get closer to getting the above to work, you're
going to want to add a '\n' to the end of that string you are writing.

I'm not familiar with IPython, but perhaps 'from myfile import *

its local and global namespaces, but cannot modify what names point to
in the closure namespace.
Of course, we can produce the same _effect_ as a computer science closure
in Python by using mutable objects...which is exactly parallel to the
difference between passing mutable or immutable objects in a function
call.

tion that would yield such an open function that
otherwise is identical to the default open.
What's the standard python idiom for when consumer code should be
able to specialize the classes used to create objects returned from
a called package? (I'm tempted to say monkey patching the module,
but that can't be optimal :)

you want next(g) to yield 3, you'd have to do something like:
g = (x for x in s[:])
where s[:] makes a copy of s that is then iterated over.

Print as function can be used in 2.6+ via 'from __future__ import
print_function'.
So it is probably best to teach print-as-function regardless.

k back further at the post which
they were commenting on. Those two lines do not constitute
consecutive lines of code, they are individual replacements
for individual lines in two different previous examples, one
of which updates the dict in place and the other of which
creates a new dict.
I thin

file? You didn't log it.
Both your statements might be true, but until you show the logging
output proving it, you don't _know_ that your assumptions are true.
