<0> arie_: what exactly do you mean?
<1> i know i can import it
<0> arie_: what kind of files? textfiles?
<1> Noet, py files
<0> ah
<0> and you want some kind of inter-process-communication?
<1> i can't import both files
<1> i mean: file1: import file2 file2: import file1
<1> that isn't possible, is it?
<1> how can i make this possible
<0> arie_: what exactly do you want to do?
<1> i can't really explain
<1> i shall try it myself again
<0> arie_: hmm ok
<2> arie: move code that needs to be shared between file1 and file2 to a new module, import that in both modules
<3> arie_: it's possible in some circumstances
<4> arie_: why not have file3: import file1,file2
<0> VladDrac: ah that's what he meant ;)
<3> arie_: http://www.python.org/doc/faq/programming.html#how-can-i-have-modules-that-mutually-import-each-other
<0> VladDrac: i thought he had a runtime-problem
<5> ok... im getting the hang of python great.. and its by far the nicest langauge ive used in a while... but im stuck with something
<5> im trying to parse a file, break down the file and use it to build a set of string variables to execute as functions
<1> tnx for help
<6> how can i append to a dict?
<5> everythign but the last bit is easy :)
<1> i didn't suspect you would understand my confusing story but you did!!!
<7> Lucractius_Azorz: You can use eval (for expressions) or exec (for statements) to evaluate code
<5> i want cmdlist[1] to become foo()
<5> so eval cmdlist[#]
<5> ?
<4> Lucractius_Azorz: see also http://www.python.org/doc/faq/programming.html#how-do-i-use-strings-to-call-functions-methods
<7> Lucractius_Azorz: Maybe. Hard to say with so little info. If all you have is a string with a function name, you can look it up in some dictionary, like using getattr to find it as a method in an object (including modules), or globals() to search in global variables.
<5> pythonologist, i knew it would be somewhere ... i have this problem in almost all languages i use lol... someones usualy got a way to do it, but it looks like python beats java hands down for simplicity... reverse indexed lookup tables... what a pain
<8> how do i flush the sending buffer, so i can be sure that what's being sent is sent out "alone"?
<5> Erwin, its a data proccessing util, so its basicly using a text config file to pick out specific variables from a pool of data at hand and then print them out :)
<9> hi all, i have this: ('SIAD_CLI', {'CLI_DES': 'NOME'})
<9> ('SIAD_CLI', {'CLI_COD': 'CODIGO'}) how can i make it into this: ('SIAD_CLI', {'CLI_DES': 'NOME'},{'CLI_COD': 'CODIGO'}), being more specific i want to join the lists that have the same first key, is there any simple way?
<8> basically so i can do: if data == "SOMETHING": at the receiving end
<8> without having to think about data received before that
<8> (i want to mark the end of a large data sending)
<7> zamba: Impossible in TCP. TCP is a stream, there are no packets. Data will arrive in order, but you can't control what chunks it willl arrive in.
<0> sapo: without having tried it - what happens if you use foo[SIAD_CLI].update(bar[SIAD_CLI])?
<7> zamba: If you need to send a bunch of data you could e.g. send the length first, or use some special char that won't occur in the message.
<9> hds, i got this: TypeError: list indices must be integers
<8> Erwin: i don't know the length beforehand
<5> pythonologist, Erwin, thanks both of you :) eval solved the issue in no time :)
<7> zamba: Well, find some message terminator that you can guarantee will not occur in the normal data, and split up messages based on that
<7> zamba: For many protocols, that is simply a newline.
<10> you could also copy http's chunked encoding
<11> is there a locale-aware way to do "somestring".lower()?
<7> Convert to unicode
<11> seems to work, thanks
<12> How can I print a float with 2 numbers after the .dot.. like 2.34 instead of 2.434323 .. I C++ I can use print ("%f.2")
<12> eh printf in C++ of course :)
<7> print "%.2f" % somefloat -- just like in C
<8> Erwin: i tried the following: data = self.socket.recv(1024)
<8> and then if "END\r\n" in data: to break it
<7> zamba: You can't do that.
<8> Erwin: cool, why not?
<7> zamba: You must buffer all data you've received and not processed and search in that.
<8> Erwin: example?
<7> zamba: There is absolute no guarantee that one send will translate into one recv. TCP is a stream.
<8> Erwin: oh, no.. this is in a while loop
<8> Erwin: while 1: around it
<11> packet boundaries is the ****
<7> zamba: And?
<8> then i break inside the if-test
<8> while 1:
<7> zamba: One receive might get 'EN' and the other 'D\r\n'
<12> oh yes stupid me..
<8> Erwin: well, i'm sending chunks of data in 1024 bytes
<13> zamba: the chunks you send and the chunks you recv don't have anything eo do with each other
<8> hm, ok.. how do i make this work, then?
<7> I just told you.
<8> the problem has been that it breaks too often, the opposite is not the problem
<8> not breaking, i mean
<13> zamba: you receive data into the end of some buffer, and process the beginning of that buffer
<8> hm.. i think i understand the theory, but not the implementation of it :)
<7> buffer = buffer + dataReceived
<7> Here's your implementation.
<7> and then you can say: if terminator in buffer: message, buffer = buffer.split(terminator, 1)
<8> ah, i think i understand
<8> thanks
<14> hi ppl. Can anyone tell me how I can enumerate a gconf key?
<14> i'm trying to write a simple compiz control panel.. but would rather create the UI based on the gconf keys rather than hardcode paths
<9> anyone could help me solving this? i have this list: [('SIAD_CLI', {'CLI_DES': 'NOME'}), ('SIAD_CLI', {'CLI_COD': 'CODIGO'}), ('SIAD_PRO', {'PRO_DES': 'DESPRO'}), ('SIAD_PRO', {'PRO_COD': 'CODIGO'})]
<9> how can i join the turples with same name.. so it would be like this: [('SIAD_CLI',{'CLI_DES':'NOME'},{'CLI_COD':'CODIGO'})
<9> its like joining what is repeating
<15> hi again ;D
<15> missed ya, lol
<16> sapo it might be even easier to put each group in one dictionary, so it winds up being: [('SIAD_CLI',{'CLI_DES':'NOME'},{'CLI_COD':'CODIGO'})
<16> ugh
<16> sapo it might be even easier to put each group in one dictionary, so it winds up being: [('SIAD_CLI',{'CLI_DES':'NOME', 'CLI_COD':'CODIGO'}) ...
<9> Zalamander, the problem is that i m loading a config file.. and i m looping.. so it repeats =/
<16> either way, it's just a matter of juggling items
<9> Zalamander, here is my code: for campo in cfg.items(item[1]):
<9> estrutura.append((item[1],{campo[0].upper():campo[1].upper()}))
<9> it prints out: [('SIAD_CLI', {'CLI_DES': 'NOME'}), ('SIAD_CLI', {'CLI_COD': 'CODIGO'}), ('SIAD_PRO', {'PRO_DES': 'DESPRO'}), ('SIAD_PRO', {'PRO_COD': 'CODIGO'})]
<16> sapo instead of "estrutura.append..." you could use a dictionary: estrutura.setdefault(item[1], {}).update({campo[0].upper():campo[1].upper()})
<17> maybe you should make a dictionary of dictionaries
<17> then when you add a dictionary itll automatically join what's repeating
<17> and then convert it back to a list
<16> sapo that will naturally group everything
<16> to get back to the list then, just do "estrutura.items()"
<9> Zalamander, thanx man.. this worked like a charm: estrutura.setdefault(item[1], {}).update({campo[0].upper():campo[1].upper()})
<9> now it outputs: 'SIAD_CLI': {'CLI_DES': 'NOME', 'CLI_COD': 'CODIGO'}, 'SIAD_PRO': {'PRO_DES': 'DESPRO', 'PRO_COD': 'CODIGO'}}
<9> Zalamander, =*
<16> ayep :-)
<18> how can i make a post request to a webserver with python
<7> ludde: using urllib.urlopen. see the docs.
<18> it doesn't seem to support post?
<18> hm
<7> What?
<18> or, data is post
<7> If the url uses the http: scheme identifier, the optional data argument may be given to specify a POST request (normally the request type is GET).
<7> ^^^ Straight from the docs
<18> yeah.. hm
<18> does python have any facility for application/x-multipart-form encode the contents or whatever the encoding is called
<18> s/for/to/
<18> it seems like it supports only application/x-www-form-urlencoded
<18> but i need to post a file to a php script.
<19> ludde: I typed "python POST multipart" into google and a number of useful-seeming items show up
<10> also, creating something yourself is not that hard ;)
<18> ok lemme try that
<20> Hello, I'm basically trying to create the functionality of a function pointer in a Python cl***... Can I simply do instance.function = myfunction ?
<20> And then call the function by means of instance.function(args) ?
<17> i dont know what youre trying to do but that looks like it would work
<20> The cl*** is a simple A*-agent, it needs two functions to calculate it's path. I want to be able to change the functions it uses easily.
<17> oh, i see
<17> that should work, yeah.
<20> inhahe: Ah, okay, thanks. My Python reference weren't very clear on that particular issue.
<21> xarragon, you can't, because methods and functions are not entirely the same.
<21> And generally speaking, functions, cl***es, whatever, are first-cl*** objects. They are just regular values.
<20> I could put the functions in the agent cl***, thereby turning them into methods?
<21> I think that what you want to do is to p*** the functions as arguments to a method, although I could be wrong.
<22> TFK, can't you use setattr instead of a.meth = newmeth ?
<20> Or how should this be done then?
<21> Yango, it's exactly the same thing, and suffers from the same problem (*if* newmeth is a regular function)
<21> xarragon, what exactly are you trying to do?
<16> a function can be externally ***igned to a method name of an instance object, can it not?
<16> so long as it allows that the first input will be "self"
<21> That won't work as expected.
<20> The agent has a method, "think()", which will run the two funktions on a set of nodes, getting a value for each node as a result. I COULD just hard-code the name of the functions, but I'd like to switch functions easily.
<23> Cl***.do_something <- function, c = Cl***(); c.do_something <- method
<21> http://rafb.net/paste/results/KSfpPv16.html
<20> All I need is the equivialent of a function pointer from C, operating on a homogenous set of functions...
<16> xarragon you can use getattr() to retrieve a function by name dynamically
<20> "homogenous" meaning that they all have the same return value and arguments.
<21> He doesn't need any of that.
<22> xarragon, it works if you replace it for a method (not even in the same cl***)
<21> Where are you getting the two functions from?
