split a string with quoted parts into list
hi there i'm experimanting with imaplib and came across stringts like (\HasNoChildren) "." "INBOX.Sent Items" in which the quotes are part of the string. now i try to convert this into a list. assume the string is in the variable f, then i tried f.split() but i end up with ['(\\HasNoChildren)', '"."', '"INBOX.Sent', 'Items"'] so due to the sapce in "Sent Items" its is sepearted in two entries, what i don't want. is there another way to convert a string with quoted sub entries into a list of strings? thanks a lot, olli -- http://mail.python.org/mailman/listinfo/python-list

Sorry for the naive question but > the documentation is really bad :-( it is pretty easy and straightforward. After you imported the re module, you can do the job with re.sub or if you have to do it often, then you can compile the regex first with re.compile and afterwards use the sub method of the compiled regex. The interesting part is re.sub(r"(.*)",r"http://www.google.com/search?q=\1>\1", text) cause here the job is done. The first raw string is the regex pattern.

don't know if it is the best solution, but it looks nice. :)
path = "/home/test"
files = [fn for fn in os.listdir(path) if

This gives you just the list of files in a given directory.

Python and encodings drives me crazy
Hi everybody, I have to write a little skript, that reads some nasty xml formated files. "Nasty xml formated" means, we have a xml like syntax, no dtd, use html entities without declaration and so on. A task as I like it. My task looks like that... 1. read the data from the file. 2. get rid of the html entities 3. parse the stuff to extract the content of two tags. 4. create a new string from the extracted content 5. write it to a cp850 or even better macroman encoded file Well, step 1 is easy and obvious. Step is solved for me by = code = from htmlentitydefs import entitydefs html2text = [] for k,v in entitydefs.items(): if v[0] != "&": html2text.append(["&"+k+";" , v]) else: html2text.append(["&"+k+";", ""]) def remove_html_entities(data): for html, char in html2text: data = apply(string.replace, [data, html, char]) return data = code = Step 3 + 4 also work fine so far. But step 5 drives me completely crazy, cause I get a lot of nice exception from the codecs module. Hopefully someone can help me with that. If my code for processing the file looks like that: def process_file(file_name): data = codecs.open(file_name, "r", "latin1").read() data = remove_html_entities(data) dom = parseString(data) print data I get Traceback (most recent call last): File "ag2blvd.py", line 46, in ? process_file(file_name) File "ag2blvd.py", line 33, in process_file data = remove_html_entities(data) File "ag2blvd.py", line 39, in remove_html_entities data = apply(string.replace, [data, html, char]) File "/usr/lib/python2.4/string.py", line 519, in replace return s.replace(old, new, maxsplit) UnicodeDecodeError: 'ascii' codec can't decode byte 0xe5 in position 0: ordinal not in range(128) I am pretty sure that I have iso-latin-1 files, but after running through my code everything looks pretty broken. If I remove the call to remove_html_entities I get Traceback (most recent call last): File "ag2blvd.py", line 46, in ? process_file(file_name) File "ag2blvd.py", line 35, in process_file print data UnicodeEncodeError: 'ascii' codec can't encode character u'\x96' in position 2482: ordinal not in range(128) And this continues, when I try to write to a file in macroman encoding. As I am pretty sure, that I am doing something completely wrong and I also haven't found a trace in the fantastic cookbook, I like to ask for help here. :) I am also pretty sure, that I do something wrong as writing a unicode string with german umlauts to a macroman file opened via the codecs module works fine.

Re: Python and encodings drives me crazy
Well, I narrowed my problem down to writing a macroman or cp850 file
using the codecs module. The rest was basically a misunderstanding
about codecs module and the wrong assumption, that my input data is
iso-latin-1 encode. It is UTF-8 encoded. So, curently I am at the
point where I have my data ready for writing
Does the following code write headline and caption in MacRoman
encoding to the disk? Or better that, is this the way to do it?
headline and caption are both unicode strings.
f = codecs.open(outfilename, "w", "macroman")
f.write(headline)
f.write("\n\n")
f.write(caption)
f.close()

Yes, this and the coersion problems Diez mentioned were the problems I
faced. Now I have written a little cleanup method, that removes the
bad characters from the input and finally I guess I have macroman
encoded files. But we will see, as soon as I try to open them on the
Mac. But now I am more or less satisfied, as only 3 obvious files
aren't converted correctly and the other 1000 files are.
Thanks for your hints, tips and so on. Good Night.

In Windows XP, you'd have to let the XP know that you're interested in input in languages other than English via "Control Panel -> Regional Settings -> Languages -> Text Services and Input Languages". There, you'd add input methods other than English. Each "input method" works in a sort of unique way, so you'll just have to learn them. For example, under English, you can use the "keyboard" input method which probably is what you're using now, or the "handwriting recognition" input method, or the "speech recognition" input method to insert english text. There are other input methods for the Asian languages (e.g. Chinese, Japanese, etc.) - Oliver -- http://mail.python.org/mailman/listinfo/python-list
Question about decorators (with context?)
Hi, sorry for the vague subject, but I can't come up with a better one so far. I am currently writing a wrapper around ImageMagicks MagickWand library using the ctypes module. During this development i have to handle exceptions in an slightly different way, then python normally handles them. I am wrapping the libraries functionality in a class that looks like that. (I leave out the ctypes calls and stuff as far as it is possible.) class MagickWand(object): def __init__(self): self._wand = @my_funky_decorator def read_image(self, filename): return You can see, I plan to have my own MagickWand object, which wraps the C struct and functions. The normal habit of MagickWand is to call a function, that returns either True or False. Based on this the user has to check for an exception or not. I will have to wrap a lot of methods to get all the functionality I need. And the checking for an exception looks always the same. So I want to write short methods, which are decorated by my_funky_decorator which handles the error checking and exception handling. Sadly, this decorator needs access to self._wand from the current object. So far I can only think of a solution, where I have to do something like that. @my_funky_decorator(wand=) def read_image(self, filename): pass So, I like to ask, if someone could enlighten me how to implement the easy decorator I mentioned in my first "example".

ctypes question about call by reference
Hi, hopefully someone with some ctypes experience can help me. I guess this is a trivial task again, but I have been googling, reading, experimenting the whole afternoon without any success. I have a given C function signature: char *MagickGetException(MagickWand *wand,ExceptionType *severity) - ExceptionType is an enum - MagickWand is somewhat strange, but so far it works fine without any type mangling. How would I wrap this thing using ctypes? Can anybody help me with that?

Then you can start wrapping them following the > instructions in the tutorial: > http://docs.python.org/lib/ctypes-ctypes-tutorial.html Well, what I learned so far from the documentation, which I already have read more then once today, is that there is no example for an enum in this situation. But looking at pygame-sdl and another project, it looks like the enum is just an c_int or c_long. And concerning MagickWand, I think I have learned, that I don't need to define the structure, if I don't want to access it. And I don't want to, cause this is handled by the library itself. Another point in this context is also, that it is not defined in the header files distributed with the library, but only in the source from which the library is built. As the file is named magick-wand-private.h it is also not meant to be edited. Is it at all possbile to use a struct without defining it with ctypes? Is it okay, to just use the int which is returned by default? Most of my library works with that configuration, so I thought it is working. Based on this, can you give me some more hints?

Re: Re: ctypes question about call by reference
After a walk outside, some fresh air around my nose and some time to relax, I finally found out how to do, what I want to do. First, define the argument types and the result type. _dll.MagickGetException.argtypes = (c_long, POINTER(c_long)) _dll.MagickGetException.restype = c_char_p Second, write correct code as it is documented. :) def get_magick_exception(wand): severity = c_long() description = _dll.MagickGetException(wand, byref(severity)) return (severity, description) And thats all. I just did the call to POINTER(c_long) in the wrong location. Now I do it as documented, and I get everything I want. I can btw live perfectly without definining what actually a MagickWand is, cause from the point of the developer just using the library and documentation, he doesn't know about the actual structure of it. The definition is hidden the C source of the library, and is not documented in the public interface.

Ctypes and freeing memory
Hi everybody, I am currently playing around with ctypes and a C library (libWand from ImageMagick), and as I want to easily deploy it on Mac, Linux and Windows, I prefer a ctypes solution over a C module. At least on windows, I would have resource problems to compile the C module. So, ctypes is the perfect choice for me. But I am currently encountering a pattern inside the C library, that has to be used to free memory. Coding in C I have to do the following char *description; long severity; description = MagickGetException(wand, &severity); /* do something with the description: print it, log it, ... */ description = (char *) MagickRelinquishMemory(description); exit(-1); /* or something else what I want to after an exception occured */ So, this looks easy and is sensible from C's point of view. Now I try to translate this to Python and ctypes. dll.MagickGetException.argtypes = [c_long, POINTER(c_long)] dll.MagickGetException.restype = c_char_p severity = c_long() description = dll.MagickGetException(byref(severity)) # So far so good. The above works like a charm, but the problem follows now # ctypes already converted the char * for description to a String object. # That means description has arrived in an area under Python's control. # these definitions are the easy part dll.MagickRelinquishMemory.argtypes = [c_void_p] dll.MagickRelinquishMemory.restype = c_char_p # but this obviously must cause problems and causes problems dll.MagickRelinquishMemory(description) So, my question is, how do I deal with this situation? Can I ignore the call to MagickRelinquishMemory, cause Python takes care of the resources already? Or is it impossible to use it at all, and I have to think about a different solution?

Re: calling a class instance of function
Hi, Methods i.e functions bound to a class instance (or object) the self argument in their definition: [code] class pid: def add(self, toadd): pass #or some sensible code [/code] If you want to define a method without that implicit self argument you'll have to make this method a static: [code] class pid: @staticmethod def staticadd (param1, param2): pass #or some sensible code [/code] Furthermore, your test() seems to be rather a function than a class: You want to use this function to test the pid class but what you do with your code below is to define a class test which inherits pid. I'm not really sure what the following lines do ... this would usually be the place to introduce class variables. Hope that Helps!

Re: what is wrong with my code?
Hi, this is the line that breaks your code: def progressTable(progress_table, action, task, pid=len(progress_table) your parameter progress_table is known inside the function, not inside its definition. So "pid=len(progress_table)" won't do. If you really think that it is possible that pid is anything else but "len(progress_table)", you should use for example -1 as the default value and calculate the length inside your functions if the parameter is not different. Otherwise dump this parameter. Hope that helps!
