[Tutor] Windows printing

I'm using this page as a reference: http://timgolden.me.uk/python/win32_how_do_i/print.html I'm able to print to the default printer ok, but I can't seem to find out how to get to pick the printer I want to use. This is from a CLI app, so there is no gui. win32print seems like it has everything

Hi Wayne, Thanks for your reply. The problem is a bit more specific. I have come across ironpython and I ran a test file and it works fine as far as the wrapping is concerned. What I want to do is write my code completely in Python (as gainst iron python), copy it to the visual studio editor and

[Tutor] Dict of function calls

For a plugin mechanism, I'm populating a dict with calls to the implemented plugins. Consider this: >>> class foo: ... def do(self): ... print 'do foo' ... >>> class bar: ... def do(self): ... print 'do bar' ... >>> list = { 'foo': foo.do(), 'bar': bar.do() } T

[Tutor] Best practice for API design handeling collections and single objects

Hi all, I've got a question for you about how to best design an API that has to handle requests for single objects and collections of those objects. My naming conventions are: Plural nouns for collections, singular nouns for single objects. "Key_to_value"-style for dictionaries. So I normaly

Re: [Tutor] Test Drive Development, DocTest, UnitTest

You might also have a look at some of the other popular testing frameworks e.g. Nose (http://somethingaboutorange.com/mrl/projects/nose/0.11.2/) and py.test (http://wiki.python.org/moin/PyTest) Both of these have the advantage that they're discovery based, so they'll go and sniff out tests from yo

[Tutor] class function problem

HEllo, I have this exercise : 3.Rewrite the increment function so that it doesn’t contain any loops. The increment function looks like this : def increment(time, seconds): time.seconds = time.seconds + seconds while time.seconds>= 60: time.seconds = time.seconds - 60
