<0> and "r+" for read/write mode
<1> not a very big one
<2> hmm
<2> outfile?
<2> do I need to define outfile?
<3> outfile = open(....)
<2> right, so.. same as fh?
<3> well, you want a separate file to write to, probably
<2> nah, I'm good :)
<2> I'd prefer to write to the one I'm reading from
<3> well then you'll have to open the file in "r+" mode... though i don't personally recommend that, you could potentially corrupt/lose the file that way
<2> oh, right
<4> Nev|Newbie: probably reading, writing to a temp file and then moving/renaming would be a better idea.
<2> hmm
<5> j0!
<2> yeah
<2> >>> fh = open('C:\Program Files\World of Warcraft\Interface\AddOns\GetDKP\dkp_list.LUA', "r+")
<2> >>> for line in fh.readlines():
<2> if not line.startswith("ENDDKPLIST"):
<2> fh.write(line)
<2> gave me a blank file :)
<3> yes, reading and writing a file simultaneously needs to be handled with great care, no matter what programming language/environment you are using
<2> yeah
<3> nearly always what you want is to make a temp file
<4> Nev|Newbie: yeah, trampling over your own feet, as it were
<5> Nev|Newbie, Hmmm. This is probably straightforward. Make it three steps:
<2> :)
<5> fh = open(); lines = fh.readlines(); fh.seek( to the beginning ); for line in lines: ....
<5> I think the seek() is important.
<2> what does seek do?
<5> Sets the file pointer.
<6> seek moves the file pointer
<2> ah
<2> tbh, I do not know what a file pointer is. Either that, or I just can't remember atm :)
<5> I don't know were it would be after a .readlines() .
<5> It's a cursor that represents where data is beign read and written to.
<2> oh right
<5> Is this program ending right away? You might need to fh.close() if you need the file-on-disk to be available for something else in the course of this program. (Thus, explaining the emptyness.)
<2> well, I'm not fully sure if python is capable of this, but my plan is to have 3 stages, and this is stage 2..
<2> first, start a bat that downloads the latest file from a server (got the bat done)
<2> then, edit the file
<2> and last, execute an application
<5> Gotcha. Yes. Close the file explicitly.
<3> you can do all that - you can even do it all from within python
<3> you will need to close the file to ensure it gets flushed out to disk
<2> yeah, the trouble is, I don't know the language awesomely well yet ;)
<2> yeah
<2> what exactly am I supposed to put in fh.seek( to the beginning )?
<2> (instead of to the beginning..)
<5> Skip the seek business. I would make a temp-file anyway. infile, outfile = file(), file(); for line in infile: if ..: out.write; ... os.rename("out", "in")
<2> :O
<5> Nev|Newbie, In general, http://python.org/doc/lib/ has all the answers. Read up on "file", the builtin type.
<2> hehe, yeah, I guess I should.. hmm
<7> Nev|Newbie: I recommend www.diveintopython.org for learning the language + some of the standard libs
<5> #python is never a substitute for docs. We wrote them. We get angry when people don't read them.
<2> you don't seem that angry :)
<2> and yeah, I added both of those links to my favs
<5> Later, all./
<2> later, thanks alot for your help :)
<2> later guys, thanks again. I might be back, but once I've solved this, I'll read up on python properly :)
<8> have fun :D
<2> :D
<9> is there anyway to protect a variable of a cl*** to be modified?
<8> i'm not sure, although a convention is that you prefix any "private" variable with an underscore
<8> it's generally understood that such variables should not be fiddled with outside the cl***
<10> hi
<9> Greatred, but I know there's a function (like __blah__) that does what I want
<9> I just don't remember ;/
<8> oh...
<10> does any1 know how to disable ctrl-c? i an using curses in python.?
<8> i don't suppose you mean properties do you, lucasd?
<9> Greatred, no
<8> in that case, no idea
<8> __setattr__?
<8> if that's right...
<9> Greatred, oh yes... that's it.. thanks a lot ;D
<8> i hope that works. i've never played with it, and it might be the wrong name
<10> does any1 know how to disable ctrl-c? i an using curses in python.?
<8> ah yes... __setattr__( self, name, value)
<8> mammuth, no, but you might try catching the exception that it raises... or maybe change the signal handler for SIGINT
<3> mammuth: wrap your code in a try: clause and catch KeybaordInterrupt
<8> i'm unsure what the normal method is
<10> aha, ok..
<11> Greatred,
<8> kbrooks
<11> KeyboardInterrupt is raised in te default sigint handler
<10> NameError: name 'KeybaordInterrupt' is not defined
<10> hmm
<10> i sess
<3> spell it right
<10> yes
<10> ;-)
<8> i wonder if programming is difficult for people with dyslexia
<8> when it comes down to symbol names etc
<10> what ISNT possible with python???!!!
<8> doing the dishes
<10> true
<8> getting girls
<10> nearly.
<3> actually, i have robots that run python :P they don't do the dishes, but maybe i can work on that ;)
<8> sweet :)
<10> he
<3> getting girls works better with perl, unfortunately
<10> i C
<8> i think you mean "pearls"
<3> nah: http://perlmonks.org/?node_id=384100
<10> hmm, i can still hit ctrl-z...
<10> must be shell prefs
<8> mammuth, you might need to catch an interrupt for that one
<3> if you want to catch that, it's a different signal than ctrl-c (i think STOP)
<3> search for how to set signal handlers in python (i don't know myself)
<10> how to except on more than one exception?
<8> aww, that perl program works too :D
<8> mammuth, it won't be an exception handler this time
<10> ok. ill try..
<8> that's a cute bit of code :D
<3> thanks ;)
<8> and she said "yes" apparently, i take it back :)
<3> hehehe
<3> we're getting married in august
<8> yay, congrats :D
<3> thanks :)
<8> i won't try that on the girl that i like, since she's not a coding geek ;)
<3> hehehe
<3> that is one thing i don't think i could do in python :p
<8> yes, the indentation rules would kill you
<8> mammuth, look in the signal module, particularly at the signal function
<3> and lack of punctuation / ability to do crazy things with goofy variable names
<8> you want to ***ign a function (or callable object) for the STOP signal
<8> yeah perl's a bit crazy like that :D
<12> she's all "(setq tab-width 8)", and i'm like "no way, girly"
<8> oh please, that's not LISP is it?
<8> or Emacs lisp maybe
<13> Hi again! :)
<8> lost the newbie tag eh?
<14> apparently, yes!
<14> someone must have made a mistake
<14> anyway, I'm aaalmost done, there's just one minor issue :)
<14> even though I do infile.close
<14> outfile.close
<14> I do not have permission to rename/delete the files
<14> because they are in use
<14> what am I doing wrong?
<3> you add parens, right?
<3> outfile.close()
<14> >.<
<8> indeedy :)
<8> which is interesting actually
