Q: scipy.xplt.subplot
by Mathias Aug. 5, 2004

Aug. 5, 2004

Hi all, I'd like to display a number of pictures with xplt.imagesc() in the same window using xplt.subplot() Now I expected 3 or 4 parameters in subplot(): -total # of plots in X dir. -total # of plots in Y dir. -number or coordinates of current plot However, there seem to be only Numy and Numx. Documentation on this function is ...well... scarce ;) Thanks for help, Mathias

distutils frustration
by Michal Vitecek Aug. 5, 2004

Aug. 5, 2004

hello everyone, i've been trying to write a distutils setup.py to compile and install getdate module by Jeff MacDonald. unfortunately, it seems that distutils doesn't support either bison or running a custom Makefile. moreover and most importantly it doesn't look like it's easy to add a support for files with the '.y' extension. please, prove me i'm wrong (i'd be happy to) :) thank you, -- fuf (fuf(a)mageo.cz)

This disturb me more than the syntax itself (which I don't like, but this not the point). I agree that Guido is the Dictator For Life, but he is supposed to be Benevolent!

DB beginner help
by Zeljko Vrba Aug. 5, 2004

Aug. 5, 2004

1. Is there any HOW-TO documentation about DB API except PEP 249? 2. How are you supposed to write DB-driver independent code when each driver has its own, possibly different from any other, paramstyle ('qmark', 'numeric', etc..)? In Perl I always use question marks and have no trouble switching the application between different databases. How do you guys do it in Python (of course, without rewriting all queries?)

curses
by Cecil H. Whitley Aug. 5, 2004

Aug. 5, 2004

Hi, I had done a quick read of the curses documentation for python. Upon the second reading I found that curses is not supported on windows. I was wondering if it would be relatively simple to use the python wrapper for curses on unix (is there such a beast?) to wrap ncurses or the like on windows? Optionally, are there any major obstacles to writing a python wrapper for ncurses or any other curses-like library for windows? Thanks, Cecil

Embedding python
by Jon_Kinsey＠Hotmail.com Aug. 5, 2004

Aug. 5, 2004

I've embedded python in a program, am I right in thinking python has to be installed on a machine for my program to work? If so how can I find out if python is installed/what version is installed - programatically and cross platform. Jon

saving streaming audio to disk
by tuanglen＠hotmail.com Aug. 5, 2004

Aug. 5, 2004

Given a URL for an MP3 audio stream, how could I write a little utility that would start the stream flowing, capture it to a disk file, and then disconnect from the stream? I'm imagining that, for example, if I save an hour-long chunk taken out of an MP3 audio stream, I would get an hour-long MP3 file on my hard drive. I'd prefer to use Python, but I'm not sure where to start. Thanks for any tips.

Re: optparse object population

Eric O. Angell wrote: > Is there a way to coerce optparse into populating an object for me? If you are dealing with just one object you can provide a custom values parameter: <code> import optparse class Header(object): def __init__(self): self.foo = "default-foo" self.bar = "default-bar" def __str__(self): values = ["%s=%r" % nv for nv in self.__dict__.items()] return "%s(%s)" % (self.__class__.__name__, ", ".join(values)) __repr__ = __str__ p = optparse.OptionParser() p.add_option("--foo") p.add_option("--bar") p.add_option("--baz") header = Header() options, args = p.parse_args(["--foo", "custom-foo", "--baz", "custom-baz"], values=header) print "options is header", options is header # True print "header", header </code> You can even expand that to work with nested objects, but it gets a little messy and you are probably better off with Jeff Epler's approach here: <code-continued> # (insert above code here) class Header2(Header): def __setattr__(self, name, value): if "." in name: left, right = name.split(".", 1) setattr(getattr(self, left), right, value) else: object.__setattr__(self, name, value) header2 = Header2() header2.nested = Header2() # I use the same class here because I'm # lazy, not for technical reasons p.add_option("--nested.foo") options, args = p.parse_args(["--nested.foo", "hi there"], values=header2) print options </code-continued> Especially, I have some doubts whether __setattr__("dotted.name", value) will always be allowed.
