<0> Does it support indexing?
<1> like [i], yes
<0> Perhaps you should make it support __iter__?
<1> that's what I'm trying to build
<2> Hey guys, I'm having some trouble with a python script I'm writing and I just can't seem to figure out what could be happening.
<1> I'm trying to implement __iter__ without making a list
<0> alus, oh. for i in xrange(self._len): yield self[i]
<1> neat
<2> Right after my import statements I'm declaring a variable: DEBUG = False
<2> I then declare another variable right after that: ALLOWED_OSX_VERSIONS = ['10.3', '10.4']
<2> I then wrote a bunch of functions that use both of those just fine.
<3> good night
<2> THe last function I wrote is main(), and it can access ALLOWED_OSX_VERSIONS jsut fine but it can't seem to access DEBUG
<2> Why would it be able to access one and not the other?
<4> what error do you get when accessing DEBUG?
<0> Maybe you ***igned to DEBUG inside main()?
<2> Yango_: UnboundLocalError: local variable 'DEBUG' referenced before ***ignment
<2> TFK: That's actually the problem; I want to ***ign a new value to DEBUG based on user input but when I say DEBUG = True it makes a new variable DEBUG in main's scope and doesn't touch the original
<0> There's your problem. Write 'global DEBUG' at the top of the main() module
<2> TFK: But why can I access it just fine from all the other functions in the same script? And why can I access the second one from inside main just fine?
<0> Because you don't ***ign to them there.
<0> (No, I don't understand it very well :-( )
<5> lol
<5> x = 2
<5> def y():
<5> x # 2
<5> x = 2 # error
<1> TFK: thanks
<5> the error is because python hasnt been told you want to change x
<2> TFK: I access DEBUG in the other functions in an if statement; if I try to put it in an if statement in main I get the UnboundLocalError
<0> http://www.faqts.com/knowledge_base/view.phtml/aid/4722 <--- by Time Peters?
<2> TFK: OK, the global thing worked. I'm going to have to read up a bit more on global scope, I think
<2> TFK: Thanks
<4> can filters be chained?
<5> Yango_, filters?
<6> What is the simplest way to load a variety of image formats on multi-platforms under python? I didn't see anything clearly in the repository.
<4> {{ myvar|default:"Empty String"|default_if_none:"None Value" }}
<6> s/repository/module index/
<4> oops wrong channel!
<7> im trying to write a multithreaded network app using threading and socket modules. Everything seems to work fine, but when I exit the program on linux, it hangs and wont quit the program. Also, the socket enters the FIN_WAIT state and so blocks restart of the program for 5 minutes or so.
<8> SO_REUSEADDR
<9> probably best to fix the problem first tho
<9> sounds like you aren't closing the socket properly
<7> in the parent, as the last statement i do a self.server.close() where self.server is the listening socket
<10> shadfc, are you using __del__ for this ?
<7> umm, im not sure what that is (new to python)
<9> http://www.amk.ca/python/howto/sockets/sockets.html#SECTION000510000000000000000 ?
<11> hi ^_^ how can i get Most stuff out an unknown exception?
<11> atm i'm printing sys.exc_info[0] and sys.exc_info[1] but even that's a little dull
<11> is there a way to get e.g an callstack?
<11> that lead to the exception
<4> uttumuttu, import traceback
<12> hi...what's the best way to sort a list of objects, based on an attribute of those objects? i've tried doing like list.sort(key=lambda indi:indi.score), but it seems to give me no joy
<4> what's the problem with that, chzmgr` ?
<12> well, it seems to do something, but not equivalent to a plain sort() :S
<4> well, it shouldn't do the same thing as a plain sort, of course!
<12> ok, this is going to be a bit of a pain to explain, so bear with me :)
<13> python newb here, how can i get a string describing an object? is there anything like php
<13> 's print_r?
<14> repr()
<14> if it's not detailed enough for you, upgrade your __repr__ method
<12> right...so i've got a list of individuals, which contain a "chromosome" - a list of binary values
<4> so, in short, there's no automatic var_dump or print_r, zeasier
<14> and yes, it's not as good as print_r, but that's a sacrifice you're going to have to make because python's object system is infinitely more complicated than tying methods to an array, like php's.
<12> calling sort on the list of individuals sorts them fine for some reason (this isnt my code)
<9> Jerub: infinitely ?
<4> check the indiviual cl***
<12> but, if i evaluate the chromosome (i.e. sum it), and store the value in a variable in each individual, and sort on this, then it doesnt sort properly
<4> and see how are __*__ defined
<13> Jerub: more complex? it actually seems simpler to me
<13> but i'll find out soon enough
<12> would __cmp__ be responsible?
<14> zeasier: php's objects are a special case of their hashmap construct.
<4> complex from the point of view of internal implementation, not from the user point of view
<13> also is there better documentation on mod_python anywhere? that is besides modpython.org?
<4> chzmgr`, probably
<12> hmmm, curious
<9> how good is mod_python anyway? better than cgi ?
<13> daveBSD: everything is better then cgi
<8> mod_python not by much though.
<13> also what is better?
<13> faster, easier?
<6> Hmm..PIL seems to say indicate that I should look at the included README for information on usage/redistribution, but there is no such file included. :/
<6> Ah..and another site seems to indicate it's BSD-like licensed.
<15> ignacio: what would you prefer to mod_python?
<8> TurboGears
<15> hm "megaframework" sounds intimidating
<4> TG comes with a production web server?
<9> well cgi is slow but i was under the impression that mod_python only supported a subset of the language
<8> It uses CherryPy.
<15> daveBSD: that's not true
<14> mod_python isn't much better than CGI at all
<4> repeat, cherrypy comes with a production web server? :)
<14> Yango_: cherrypy IS a production web server.
<4> CherryPy's HTTP server is pretty good but let's face it, it is no Apache. For this reason, you might want to run your CherryPy site BehindApache in some cases.
<13> heh, megaframework. is that a framework with more then average bloat?
<9> heh. cherrypy
<14> zeasier: well, it's actually a framework containing frameworks. it contains sqlobject, cherrypy, mochikit, kid, etc.
<4> so it's a metaframework instead
<14> Yango_: yeah, putting it behind apache is probably a good idea, and there's detailed docs on how to do it.
<14> Yango_: but saying that something is 'no apache' isn't exactly a positive thing. apache is a bloated piece of ****, that just happens to be really quite good at serving static content and php pages.
<4> Jerub, then what do you get of using that combination instead of apache+mod_python + some other framework?
