<0> for x in enumerate(list) <--- is this a single interation over a list?
<1> Yorick: uh, they're implemented to behave exactly like lists.
<0> or an enumeration... then an iteration?
<1> Yorick: 'array' is an outmoded broken concept from the days when you had to malloc() and free()
<2> jerub, can file do that?
<1> triplah: it's a single iteration
<1> dave___: do what?
<1> dave___: you just said "file stream", and I have no idea what you meant.
<2> jerub, i'm trying to read in from a file and apply a regexp.. but the file is 2GB, so i don't want it in memory
<3> Yorick: but u can just append stuff to a list, cant u ... while when u r dealing with arrays in some other languages u would have to check array length etc
<1> dave___: oh, yeah.
<1> dave___: just
<1> for line in file('myfile'): ... will do it.
<2> the regexp is for multiple lines
<1> is it binary data? if it is, it might be a long way between newlines, and iterating like that will go a line at a time.
<3> in that way they are more like java vectors, u just append without thinking about length etc :)
<2> jerub, it has to read in an arbitrary number of lines before the regexp will match, but after that, i want it to free up the now unused memory for what it read in so far
<1> milosn: that is because a vector is very much like a 'list'.
<1> dave___: yeah, so you do:
<1> mydata = ''; for line in file('myfile'): mydata += line; dostuff, if match: mydata = ''
<3> whatever it is ...
<2> jerub, good idea, i can use a StringIO object for that to make it fast, too.
<3> ill go and do something usefull
<1> dave___: no you can't.
<1> dave___: the regexp engine works on python str's, it can't work on a StringIO object.
<1> so if you want to match in 'mydata' not in 'line', you need it as a str regardless.
<2> yeah, but it's easy to just cstr.read()
<1> yes, but less efficient.
<4> re
<2> less efficient than creating 900,000 string objects?
<1> hence me saying, "no its not"
<1> dave___: .read() will create exactly the same number
<1> it will just add StringIO objects too
<4> hi guys - http://nopaste.php-q.net/194848
<1> two strings -> one string <= two strings -> stringio object + 1 string
<4> could you take a look at it?
<1> yuck.
<4> Jerub, don't worry - it'll just blow your monitor
<4> and probably your mind because of the ignorance with which the code was written
<4> info is as you can see the made out of some parts - it could be getTitle() for example
<2> jerub, ok i see. thanks
<1> FILE has no attribute info
<5> Is there a more elegant way to do dict([(k,v) for k,v in oldDict.iteritems() if v>0])?
<1> Wu: don't use an /away script
<4> when i call tag.info it should use what stands inside of info (in the example getTitle())
<4> but it doesn't
<4> how can i make it do that?
<6> sorry about that, crappy irc client
<1> luh: you mean to use +info+ not +FILE.info+
<6> i have it enabled by default and i forgot (i do not usually use /away)
<1> Wu: thankyou for your attention. we appreciate your help in this matter. :)
<7> luh: they are about to tell you that it is evil...soon you will believe it is evil... but you can use exec(info) and if info is 'getTitle()' and you have a getTitle() function it will call it
<8> how do i launch something in a separate process instead of a thread?
<4> cb921, you mean +FILE.exec(info)+ ?
<4> Jerub, using only info doesn't work
<9> w1ldch1ld: os.popen is one option
<2> w1ldch1ld: fork
<4> cb921, it might be really evil what i do atm - but i'm beginner - and atm i can't see a better solution - when i get better i'll probably fix these youth-sins
<4> or you show me how to do it better
<8> dave___: thanks. shall look it up.
<7> luh line 27 needs only 'info' not FILE.info
<4> but it doesn't know on which object info is called or?
<7> Then use getTitle(FILE) and change the getTitle function to be def getTitle(FILE):
<4> hmm - it stopped writing completely
<4> (with the changing from File.info to info)
<10> has anyone ever used win32com.client.Dispatch to get COM access to firefox? can it be done, i have been having trouble finding any docs about it.
<7> luh - is this where you want to RUN the function stored in info?
<11> donkeyboy: well I do use this for other things....whats the prob? good docs are the win32 for python programmers (oreilly) and ActiveState python 2.4 docs
<4> yeah - because that should return a string
<4> and that's the one i want to write in there
<10> m0no: i have no problems using it for IE and other windows apps, but i am not able to find any docs with refrence to firefox, like its application name and wat functions it makes callable from the COM interface
<12> hm I need to create a function object that accepts a few parameters but has a few set by the creator of the object, can I use a lambda to create this?
<4> cb921, info is a member function of a tag object - which returns me a string with some informationabout the tag
<11> donkeyboy: did you see this? http://developer.mozilla.org/en/docs/PyXPCOM
<4> okay - i'm trying to get the information out first - save the information in a string and write that string
<4> so i'm trying :
<4> savedInfo = exec info
<4> but that won't work either
<10> m0no: taking a look at it now, thanks.
<10> wats up with IBM? the last couple days every article or doc i have tried to look at has either been not found or i get an sorry note
<11> is it better to go from blah import * or import blah
<9> m0no: as with Java, importing every name is considered not ideal style "polluting namespace" - but it saves typing the module prefix
<13> mono: if you must, it's best if you "from blah import bar, baz, badtz, blergh"
<14> mcmillen: not even 'foo' ?
<14> this code sure ain't gonna work.
<15> %sorted
<15> where are sorted() complete docs?
<15> and how can I use pyn to find it out?
<16> hey, how can i parse back a email.MIMEMultipart.MIMEMultipart instance from a string (that is a flattened version of an original email.MIMEMultipart.MIMEMultipart instance)
<16> ?
<17> I need to a website, which needs cookie support, is that possible with urlgrabber, or do I need pycURL ?
<18> milosn: No.
<17> +connect ^^
<19> Wondering if could ask what might be causing supybot tonot connect to chat.freenode.net? ;)
<20> hi
<20> how can i check that two lists intersecting?
<21> convert them to sets
<18> set(a) ^ set(b)
<20> thanks
<22> http://www.google.com/search?q=python+two+lists+intersect
<21> The ^ is the difference rather than intersection
<18> no, - is difference.
<18> ah sorry, I meant &
<21> >>> set([1,2,3]) ^ set([2,3,4]), set([1,2,3]) & set([2,3,4])
<21> (set([1, 4]), set([2, 3]))
<21> Symmetrical difference then
<18> Right, symmetric.
<23> Hi all
<23> Ciao a tutti, c' qualche Italiano?
<9> un bottiglia di vino bianco, per favore
<15> sorted(...)
<15> sorted(iterable, cmp=None, key=None, reverse=False)
<15> what is cmp and key?
<23> we pythonologist :)
<21> see the list.sort docs, yango
<21> they are here -- http://docs.python.org/lib/typesseq-mutable.html
<23> pythonologist, ci sei?
<21> cmp is mostly obsolete, when sorting through any other order than the default or reverse, you should use e.g. key = lambda x: get sort key for item x
<15> how do I do it if I want to sort an object list by some of its attributes?
<15> the equivalent of this pseudocode: sorted(object_list,key=object.attribute)
<15> lambda x: x.attr
<15> :)
<24> Yango: there's actually a key= argument in list.sort... though I'm unsure if it'll work on attributes, it might just work on array-like objects. you could write your own cmp function and p*** it to the sort function though
<5> Yango and Crast, key is a function argument. lambda p: p.foobar
<24> AKX: aha
<25> Yango operator.attrgetter('name')?
<21> Just don't use cmp functions anymore.
<25> Yango, or operator.itemgetter(1) if you want the 2nd item from a sequence of sequences
<15> robrien, lambda and key work fine
<15> hmmm, is there a way to mimic sql's sort behavior with sorted?
<15> select * from table order by column_A, column_B
<26> Yango: Which SQL behaviour?
<15> order by
<15> sorted(sorted(list))
<26> yango: sorted(key=lambda o: (o.col_a, o_col_b))
<26> Yango: tuple just happen to have the right sort order for your sorting requirements ;)
<27> i say u use def
<27> its simpler
<28> sort has several optional keyword options, depending on what you want it may be possible.
<28> wow, I'am lagged.
<26> sysfault: yes you are ;)
<28> --- Ping reply from yacc : 0.83 second(s)
<16> if i have a Message part that was parsed in from a mime email is there anyway to say give me the "text" payload (decoded from base64 if it was encoded that way) ?
<21> yacc: What gets more tricky is mimicing ORDER BY cola ASC, colb DESC, colc ASC :)
<15> yacc, but that won't let me do order by col_a ASC, col_b DESC
<15> will it?
<21> rockyburt: you have to use .walk() to walk over the messages, find the text/plain type and call get_payload(decode=True)
<26> Erwin: Yes it's more tricky.
<21> rockyburt: OR if there is no text/plain payload, ***ume the body is the message
