<0> Mrdini: Isn't that what the name of the company they work for is?
<0> Mrdini: Ah.
<1> it's been too long :P
<0> Mrdini: I never knew what it's official designation was.
<2> kosh: how can i put self in it?
<2> the decorator takes the function as argument..
<3> def wrapper(self, *args)
<3> change the wrapper to that
<2> :o!
<2> no way!
<2> kosh: awesome, thanks
<4> /away Z
<4> ops :P
<5> ah, mailman day comes around so quickly
<6> And it's such a mess when you're on 50+ MLs...
<5> I'm not on quite that many... anyway, time to go to Australia...
<7> hi how do I print the set of alphabets A-Z dynamically?
<7> B doesn't seem to be 'A' +1
<8> hiya
<8> is python good for network programming
<8> ?
<6> print [chr(x+ord('A')) for x in xrange(26)]
<3> a_staff: what do you mean by network programming?
<7> thanks ignacio ord converts A alphabet into ascii range?
<6> A character into its ASCII/Unicode value.
<7> aah cool
<8> kosh i want to learn networking deeper.. and what i mean is for socket programming
<6> chr() does the reverse for SBCS, unichr() for Unicode.
<7> thanks ignacio
<3> socket stuff I think you can do but I am not really familiar with that
<3> with higher level stuff there is twisted
<8> kosh what dou mean by that?
<8> higher level stufff?
<6> Not dealing with raw sockets.
<3> http, ssl, ftp, ssh etc etc
<0> So here's a hypothetical, guys:
<6> "A friend of mine, yeah, he has a problem..."
<0> I have to get rid of the data on a hard drive. How hot would I need to heat it deolarize it?
<6> You're looking for the "Curie point".
<3> just melt it down entirely
<6> No need.
<3> however what is so sensitive you have to go to those lengths to destroy it?
<8> kosh u mean application layer stuff? hows that? i mean what is python good at networking?
<0> Nothing.
<3> ignacio: of course there is no need, but it is more fun :)
<0> It's a hypothetical.
<6> http://en.wikipedia.org/wiki/Curie_point
<3> a_staff: I deal with database apps, I don't do socket layer stuff at all so I don't know how well python works for that, but it must work pretty well since http, ftp etc are all built on top of it
<0> I'm just thinking if the MIB ever are coming, could I fix my problem by hitting my computer a few times with a hammer, and then throwing it in the oven.
<9> I need to generate automatically a set of functions in a cl*** based on the keys of a dict. For example, cl*** a: p*** dict = { 'a1': 42, 'a2': 43 } create_methods(a,dict) and having as a result cl*** a with methods meth_a1 and meth_a2
<9> what would be a good way to go and do it?
<6> setattr()
<6> Of course, you'd need to generate closures first.
<9> explain that to me, please :)
<8> kosh, hows python in database?
<6> First, you generate the closure. Then you use setattr to stick it to the cl***.
<3> a_staff: seems to work fine
<8> kosh the libraries...?
<6> Look elsewhere for info on generating the closures.
<3> a_staff: I have been doing zope devel for about 6 years now and it works very well
<9> what _is_ a closure :)
<0> My oven is not that awesome. :-(
<6> It's a function that takes a variable at a point in time and uses that as one of the arguments in an algorithm.
<8> anyone does network programming with python?
<0> I'd like to get back into python developement.
<0> It's so much more fun to code in than C.
<9> is there another way to generate closures than lambda? the function I need needs to return and maybe print
<6> You can do it with a cl***. Wikipedia shows how to do it that way.
<10> i thought you do closures in python by using default arguments
<11> AirCastle: a closure is a function which "remembers" the stack frame where it was defined
<9> setattr doesn't bind the methods though
<6> Yes, yes it does.
<6> Make sure you remember the self arg.
<6> foo=lambda x, y: return y+3 \ cl*** bar: \ baz=foo \ bar().baz(4)
<8> :)
<9> http://pastebin.com/577946
<6> Argh. Kill the return there obviously.
<6> Hrm...
<6> wfm
<6> http://rafb.net/paste/results/gqU6ib83.html
<9> ignacio, so you bind them first... i found about new.instancemethod
<9> which is probably more generic
<9> else i would have to bind all new methods beforehand which kinda beats the purpose of dynamically generating the functions
<6> I used del on it and it still worked after.
<9> ignacio, dumb me i was using a instead of a()
<12> Yango, check PEP 227 regarding nested scopes
<9> why doesn't this work? (Invalid Syntax) eval('Orderer.get_'+item[0]+'_order = new.instancemethod(order,None,Orderer)')
<13> can you tell us the exact error message
<14> oh my f-ing god.
<3> umm wouldn't that be reversed?
<14> Yango: I've just revoked your coding privelidges.
<3> Jerub: can I provide the ammunition?
<13> Jerub: I wasn't going to comment :-)
<14> kosh: no, radix came round in divmod's time machine and gave me two crates, I didn't know why until now.
<9> Jerub, before you kill me, tell me my mistake :) (besides the ugliness of the intent)
<14> Yango: what you actually want is something like:
<14> Orderer.order[num] = order
<14> then Orderer.order[num]() will work fine.
<14> but that's just ****ed up anyway, write a couple methods and do dict lookups.
<9> Jerub, that's not what i want...I want to add methods with a name based on some string var
<15> Yango: whan not getattr?
<15> s/get/set/
<14> Yango: oh, I don't care what you WANT. this is what you are going to DO.
<15> setattr(Orderer, 'get_%s_order' % item[0], new.instancemethod(order, None, Orderer))?
<9> yes, i've been playing with that, mitsuhiko, but got problems with binding the method
<9> so that eval call was a desperate shot at the problem :)
<15> Yango: than ***ign it over the dict
<15> Orderer.__dict__['get_%s_order' % item[0]] = new.instancemethod(order,None,Orderer)
<14> mitsuhiko: die.
<9> so desperate that it backfired
<9> :)
<15> Jerub: i know why he wants that
<14> mitsuhiko: I don't care.
<15> if you would know why you would care
<15> cl*** C(object):
<15> def __init__(self):
<15> self.__cl***__ = OtherCl***
<15> Jerub: does that look silly in your mind?
<14> mitsuhiko: no, it looks unnecessery.
<14> mitsuhiko: present a use-case
<15> Jerub: you have a queue
<15> when you queue is longer then 100 entries it should change it's usage case
<15> then you can do self.__cl***__ = SpecialQueue
<14> huh?
<14> mitsuhiko: why should you do that?
<15> much faster than always doing if len(self) > 100: ... else: ..
<15> Jerub: because this is a typical pattern?
<9> thanks mitsuhiko, worked perfectly
<3> that doesn't make it a good idea especially in python
<16> it's been a while since i've used python, and i'm looking at the "Tutorial" section to refresh how to create a cl***... aren't we still supposed to declare a cl*** like so: "cl*** X(Object):...", or can we just do "cl*** X:..." now and it inherits Object?
<15> kosh: but it's fast
<14> mitsuhiko: bah, this shows a fundamental misunderstanding.
<14> mitsuhiko: and pre-emptive optimisation.
<3> I sitll don't see how this helps with speed or anything else for that matter
<14> neither do I.
<14> mitsuhiko: hey, is it fast?
<15> Jerub: replacing the cl***? yes
<14> mitsuhiko: show me the results of your tests using the profile module.
<14> in fact, which profile module did you use?
<15> Jerub: no one? all you have to know is a bit of python interna
<15> if conditions take time
<15> replaceing a cl*** *one* time doesn't take time later
<13> :-)
<14> mitsuhiko: oh, so you were just prematurely optimising
<14> I see.
<15> i only said that this is useful
<14> Don't do that. Don't encourage ****ty practices based on premature optimiation because you think you know better than the profile module.
<15> i don't use it in my code
<3> what if statement is there in this?
