Re: No more Python support in NetBeans 7.0
Sorry to comment on an old topic, but I wanted to clarify for others like me who might get the wrong idea. It looks like this is no longer true. Netbeans 7 might be supporting python after all. http://wiki.netbeans.org/Python70Roadmap -- http://mail.python.org/mailman/listinfo/python-list
Re: How to Nest Structs?
Try unpacking the nested struct as a fixed width string and then unpacking the
string.
Then unpack the string

The site can be used by anyone - someone in the corporate world, musicians, artists, whatever. So... please check it out, and if you like it, we'd appreciate you spreading the word and telling all your friends :) Thanks, The Webmaster, www.webmeeters.com -- http://mail.python.org/mailman/listinfo/python-list
Gecko bindings for Python?
Hello, I'd like to use the Gecko engine in GTK+ or Qt programs written in Python. Could you recommend a module for this? A tutorial to get started?

for line in file weirdness
Hello, here's a strange bug (?) I've came across (using Python 2.2): # loop_1 for line in file: if some_condition(line): break do_something() # loop_2 for line in file: do_something_else() The problem is, that loop_2 doesn't resume where loop_1 left off, but skips many lines (a block's worth or so) before continuing. Why is this? Is reading from a file non-reentrant? It is always possible to slurp the whole file content into a list, and then iterate through the list, but I want to handle HUGE files too.

Re: for line in file weirdness
Thanks :) Reading everything into a variable was not an option, due to some very large files. Creating the iterator only once, as Fredrik suggested, solved the problem nicely. Again many thanks for your great support! -- http://mail.python.org/mailman/listinfo/python-list
MIME-Version in interpart, Python MIMEMultipart
list - using python's MIMEMultipart() object I've noticed that it interjects a 'MIME-Version' in the interpart header, like so... --some_MIME_Boundry Content-Type: text/plain; charset="us-ascii" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit some_test Now, RFC1521, section 3 reads: Note that the MIME-Version header field is required at the top level of a message. It is not required for each body part of a multipart entity. It is required for the embedded headers of a body of type "message" if and only if the embedded message is itself claimed to be MIME-conformant. What I'm wondering is if anyone knows if the inclusion of the MIME- Version in the interpart header is invalid. It does not look like it to me, byt I'm looking for your opinions.

The best thing I find is python is very easy, the best part maybe because of my inexperience with other languages are the List and Dict data types that just solved problems I had in real life made solvable with python very easily. when I had to worry about memory and pointers to memory in those other languages, python just made me focus on the solution I want. also the way I can read python program just like they are written in plain eglish :) a personal problem I tried to solve is that how many characters exist in a sequence statistically (with 2 or more characters in len) in any given file and then their count. For a 100kb file I used practially all programming knowledge in from the other languages but failed miserably as the computation were taking more time with each bigger chunck of file. I would have to do a lot of memery management with python using those style like deleting list and dict before adding another. but when I tried to solve the problem natively with python it just took a blink of an eye for them to solve upto 50kb file. but for larger files although instant it is just memory consuming since I was limit with 2 gb I ddin't poke further. this was my exp and I find programming fun in python like ironman talking to jarvis keep computing!!!

What a curiously incomplete announcement. Could you tell us what xlwt is? I see no hint here. Heh, this and its sibling package, xlrd, are Python packages for writing and reading MS Excel files. Unlike other Python Excel-manipulation libraries I've encountered, they don't rely on having an installed copy of Excel and can thus run on platforms where Excel doesn't. They've been pretty robust based on my poking at them, have been around a good length of time (meaning more bugs have been worked out), and Chris posts release notes here pretty regularly. Regularly enough that I'm pretty sure this isn't the first time he's omitted the "this is what xlrd/xlwt is" line in his announcement. :-) Thanks to Chris for all the dirty work done mucking around with .xls internals to make these modules. -tkc xlrd and xlwt have been of great help to me since the time i started using python. thank u for such a nice library.

re.match and non-alphanumeric characters
Dear all,
this is really driving me nuts and any help would be extremely
appreciated.
I have a string that contains some numeric data. I want to isolate
these data using re.match, as follows.
bogus = "IFC(35m)"
data = re.match(r'(\d+)',bogus)
print data.group(1)
I would expect to have "35" printed out to screen, but instead I get
an error that the regular expression did not match:
Traceback (most recent call last):
File "C:\Documents and Settings\Mattia\Desktop\Neeltje\read.py",
line 20, in
print data.group(1)
AttributeError: 'NoneType' object has no attribute 'group'
Note that the same holds if I look for "35" straight, instead of "\d
+". If instead I look for "IFC" it works fine. That is, apparently
re.match will match only up to the first non-alphanumeric character
and ignore anything after a "(", "_", "[" and god knows what else.
I am using Python 2.6 (r26:66721, latest stable version). Am I missing
something very big and very important?
