<0> hey!
<0> i am thinking of learning python. what greats things can be produced using python?
<0> as in applications, etc.
<1> Pretty much anything your little heart desires
<0> nice
<0> :D
<0> thanks
<2> what is the official channel for python discussions?
<3> hmm
<4> 'ello
<3> helo
<4> when using popen2, when you run a command, does it stay active until there's a result code, or...?
<5> exoxe, let me see
<5> it stay active
<5> >>> x = os.popen2("nc -l -p 80")
<5> >>> x[1].read()
<5> i was in read() until i got something from netcat
<4> cool, thank you :)
<5> :P
<5> but...
<5> if you only set
<5> x = os.popen2("nc -l -p 80")
<5> you can still run other things
<4> okay, good
<3> Sure, popen just launches a new process (concurrency implied), connecting its stdin/stdout/stderr to some file descriptors in the caller process
<6> hi, are most python books written for use in windows -- or linux?
<6> or both?
<6> for networking?
<7> jksd: most books are written for every platform python can possibly run on
<7> there are python books related to networking, xml, etc ..
<6> i c
<6> eniac_: thanks
<8> there is an article for using IronPython in .net
<7> FMJaguar: google !
<7> and IronPython is dotnet
<9> hi, how can i convert wide character string to multibyte?
<9> mmm.. and vice versa
<10> I don't get it. A wide character is multibyte.
<9> nope
<9> wide is unicode
<9> mb is mb
<10> Can you give an example?
<9> Multibyte character sets (MBCSs) are an alternative to Unicode for supporting character sets, like Japanese and Chinese, that cannot be represented in a single byte.
<9> Under MBCS, characters are encoded in either 1 or 2 bytes
<3> use Unicode strings internally and decode/encode to the character set of your liking when reading/writing ?
<11> howdy folks
<9> just i got unicode string on input, but the program to which i should forward the string doesn't understand unicode, so i should send it mbcsed
<10> sc__: So what you're asking is how to convert a unicode string to an arbitrary non-unicode encoding?
<9> mm, something like that
<11> if I wanted to find every instance of the piep symbol in a line with re, whats the simplest way to do it?
<11> pipeCount = re.match("\|",someText)
<3> sc__: u"Foo".encode ("utf-8") or whatever you prefer
<11> er, pipe, not piep.
<10> http://docs.python.org/lib/standard-encodings.html
<10> sc__: For instance myunicodestring.encode("iso2022_jp")
<3> EyePulp: if you're just counting, then "foo|bar|baz".count ("|") will do
<9> hund, okie thanks, i'll check it out
<11> yason: that did it nicely - now how about doing modulus math? know the symbol?
<11> % ?
<11> it is %
<11> =)
<3> EyePulp: it's %
<10> Yes. And you might want to use divmod().
<11> any reason?
<10> "a, b = divmod(x,y)" is the same as "a,b = x/y, x%y".
<10> Only faster.
<11> ah - I see. No, I'm just looking to verify an even number of pipes in a text line.
<11> filtering imported data before it clogs the system - they seem to send us poorly delimited lines. I just realized a very simple way to see if all the columns are properly delimited is to test for an even number of text delimiters.
<10> I usually write a simple, but strict parser, and if it ends up raising an exception, the data is per definition not well-formed.
<10> I don't know if that applies to your case, though.
<11> oh, we're not well formed. it's not a question of that. but it's harder to get the client to clean their export than it is just to pull the bad lines on import.
<11> =)
<3> is that like a negative bug countered by a positive bug?-) instead of both fixing their part..
<11> naw, my filter just loops through their data, and if something is ill-formed puts it into an exception report. But it then runs the good stuff.
<10> Duct tape. ;)
<12> Greetings. I want to ask something. What does that [ :-1 ] means ? ( I usually meet it in file IO )
<3> Indy: the beginning of a sequence, except for the last item
<11> it also make for a fun emoticon.
<12> what do you mean the "beggining" of a sequence ?
<3> EyePulp: "careful coder"
<3> Indy: Well, as opposed to the ending of a sequence :-)
<9> hmm, doesn't seem to work
<9> always get UnicodeDecodeError: 'ascii' codec can't decode byte 0xe5 in position 0: ordinal
<9> not in range(128)
<13> that means you're converting a Unicode string to ASCII (perhaps implicitly)
<9> on s.encode('gb2312')
<13> and the Unicode string has non-ASCII characters
<9> but it's chinese
<13> yes
<13> that won't convert to ASCII
<9> sure thing it will not be in 128 range
<9> hmm, but how can convert unicode string to multibyte chinese?
<13> s.encode('gb2312') is probably fine; the problem is likely that you're doing something like printing the resulting Unicode string on an ASCII terminal
<13> check your traceback to see where the error's coming from
<9> nope
<13> well that's what the error means
<13> can't help you without seeing the code and exact traceback
<9> it stoppes on this line
<9> and i just push this string to another function
<13> I told you what the error means, not sure what more I can do
<13> you are trying to convert a Unicode string containing non-ASCII characters to an ASCII string, whether you think that's what you're doing or not
<9> okey, just this error is on top of call stack
<9> i mean the line, where it appears
<13> well you haven't shown the code or the traceback
<9> hmm, explain me then: my code get a chinese UTF-8 encoded string from the site, then it should push it to irc channel for example, while irc doesn't support unicode i should convert it to gb2312 encoding - it's multibyte
<13> I understand what you're trying to do, there's nothing theoretically wrong with that
<13> the problem is that you're ALSO converting the Unicode to ASCII at some point and that's failing
<13> without seeing code and the exact traceback, it is impossible to help you further
<9> http://rafb.net/paste/results/dwDsvl90.html
<9> look at this
<11> would this return True or False from the single statement? isEmpty = emptyFilter == lineText aternately, is there a ternary operator in Python?
<13> yes, the result of the ***ignment will be false
<13> no, no conditional operator (at least no substitutions you'd be happy with)
<11> what if emptyFilter == lineText - would it return true?
<13> sure
<11> hrm
<13> a == b will return True or False (presuming they're builtin types or well-behaved custom types)
<9> xihr, could it happen that i get unicode string, but python things that it's ansi?
<9> and that is why this error occurs
<13> that's not what the error is
<13> I really don't know how to explain what the error means any better than I already have
<4> does urllib.urlopen timeout, or will it constantly wait until it gets an EOF (or whatever it looks for)?
<4> i.e. if a webserver is pegged out and it opens a connection, will it ever return an error by default?
<4> or do I need to use socket
<13> I think it will eventually timeout, but it may be a long time
<4> well, it ran for a few minutes.. hehe
<9> the point u're talking about is _that_ point which i've shown
<9> there is no other conversions
<9> just got string and convert
<9> nothing else
<9> just u can specify timeout yourself
<9> by importing socket and use setdefaulttimeout()
<4> yeah, I already did.. thanks :)
<6> what's python like for network programming?
<6> pretty decent?
<13> yes
<13> sc: the point is, you're probably doing an implicit conversion and not realizing
<13> without code and traceback, it is IMPOSSIBLE to help you further
<13> so either use a pastebin to show us or you might as well drop it ...
<13> sheesh
<13> heh
<13> hey I have a problem I'm trying to solve! could you help me solve it? I won't tell you what the problem is, though
<13> you have to guess what the problem is and then give me a solution
<11> ooh, let me go first!
<1> hehe
<13> it kind of surprises me how many people basically REFUSE to be helped
<13> "I have problem X" "it's because of issue Y" "no it isn't"
<1> *nods*
<1> So that was the worst "thai" meal I have ever had
