py2exe + win32com + DAO
I have a Python code module that adds records to a MS Access database. The following line of code executes successfully when the code module is run as a Python script: daoEngine = win32com.client.Dispatch(r'DAO.DBEngine.36') It also runs successfully when the Python script is compiled and run as an executable using the Py2exe utility. However, when the compiled executable is called from VBA using the win32 CreateProcess function, the preceding code produces this output: !!python/name:pywintypes.com_error '' What is causing this error? -- http://mail.python.org/mailman/listinfo/python-list
Re: py2exe + win32com + DAO
I do not believe your assertion applies to the following line of code: daoEngine = win32com.client.Dispatch(r'DAO.DBEngine.36') The preceding code snippet instantiates a COM object and is prerequisite to creating a reference to a specific database: daoDB = daoEngine.OpenDatabase(dbname) As the compiled Python module executes successfully when invoked from a command-line but not when invoked using the win32 CreateProcess function, I suspect that one or more of the arguments to CreateProcess is preventing successful execution. I will investigate this further (possibly on a win32 forum); however, is it possible to obtain more verbose error output from Python modules?

Tkinter Window On Top
Can a Tkinter application create a COM object and keep its own window
on top of it?
excel = win32com.client.Dispatch('Excel.Application')
I would like the user to be able to see and interact with the Excel
application but keep the Tkinter application on top.

2d barcode library?
Is anyone aware of a good library for building 2d barcodes (any format will work for me) and outputing them as some picture format, presumably png or bmp to be used for html printing?

Installing Python 3.1.2 from source, how do you resolve the sqlite3-dev dependency?
Running ubuntu 9.04 "jaunty". When I run make I get the following error: Python build finished, but the necessary bits to build these modules were not found: _sqlite3 So the easy solution is to just install the missing dependency using apt-get, "sudo apt-get -f install libsqlite3-dev" but I get the following error: The following packages have unmet dependencies: libsqlite3-dev: Depends: libsqlite3-0 (= 3.6.10-1) but 3.6.10-1ubuntu0.2 is to be installed E: Broken packages I tried uninstalling "libsqlite3-0" but synaptic said many things needed it (50+). So now I am stuck. I can't install the missing dependency. And therefore I can not install python 3.1.2. **Any ideas on how to fix the missing libsqlite3-dev dependency?** -- http://mail.python.org/mailman/listinfo/python-list

AI Example Help
Hello all, For the first time in well... a very long time I am coming to a loss on where to really get started here on the project I wish to undertake to help me really get into Python programming. A quick explanation of how I learn. I learn best with example working small code bits. With the code I then disect it to understand how each part works. (within "beginner" limits of course). I have been looking around the web and google searching a whole lot the past week about and really have not had much luck on what I am needing / that is really helpful. So, I am here to beg/plead for some help on this. My end game goal is to create a "hybrid" chat bot. Such as that you can ask it questions and talk to it etc. Such as asking "What's the server's current load?". I found out I could do that with the HOWIE bot I have been playing with. But, I am looking to build up a more "AI" system where instead of me asking all the questions, the bot can yell at me and say " HEY THE SERVER IS OUT OF RESOURCES". Further developement will lead to a FAQ style bot as well. Such as that where I can ask them things like (for a very basic example, what is a 404 error?), or even (what is causing a 500 ISE on the site? [by having it read the logs and tell me what the logs say for the site]) These are just the basics to help me get started. As I get more advanced and better at this, I would like to be able to have it crawl sites and learn different informain. Something as far fetched and I consider a "dream" would be it crawling the cpanel forums and gathering up the responses to questions so that I could query it as well. So, as I really, really, hate to have to ask. Does anyone have any example coding in what my basic needs are? As I feel that working off the HOWIE bot won't turn out to what I am wanting and then I will end up wasting a whole lot of time going in the wrong direction. Which is also why I am here TL;DR I really would truely appreciate and example coding of how to put together an initial basic "AI" bot where it can monitor the system and tell me alerts as with being able to query it for questions. As with I am looking for some sort of time efficient way for it to gather it's own data. As otherwise all the information I would have to manually put in would be extreme. I greatly appreciate any help you guys can prodive me with to help me get started. Before you assume I want everyone to do all the work for me, it's not the case. It's just that I learn best/faster from example code. Also, I am thinking of going with python 2.7 for this since it seems all the documentation I run into isn't for the 3.x Python. Thank you so much anyone who can help me. Also, if you are someone who actually knows how to do everything I have mentioned, I would even ben willing to hire a "tutor" to teach me these things. -- http://mail.python.org/mailman/listinfo/python-list

This is what I have actually been thinking of doing is splitting up the HOWIE bot. But, that is one thing I am working on still to really figure out how to split it apart between automagicness of telling you things without user input. And then the input and answer part. Although, from what I can think of at this time is to write a main program that is the "Automagic part" and then it can call in Howie as needed? > > > > I would also recommend using Python 3.3, for several reasons: > > * There's plenty of docs for 3.3; perhaps web searches are > > highlighting 2.x, but if you go to the main docs page[2] you'll find > > 3.3 there. > > * Py3 has much better Unicode support than Py2, a significant factor > > when you're working with natural language parsing > > * The 2.x line is no longer being developed.

Writing formatted data (numeric) to a binary file
I am just starting to use python, and as such my question may well be a bit simplistic. I am currently trying to write what should be a very basic set of routines for reading and writing to a binary grid format (ERMapper). However: I am struggling to find the correct tools to write a row of a 2-dimensional array to a binary file. In matlab the command looks like: fid=fopen(filename,'wb'); for y=1:NrOfLines fwrite(fid,in(y,:)','real*4'); end fclose(fid); I'm conscious that the "write" command would allow me to write text to a binary file, but I'm not clear how to: 1) format my numeric data such that it matches the real*4 format 2) parse an entire row of a 2D array without using a for loop. If anyone has any suggestions on how to do this (or even hints as to what modules I should be looking at) they would be greatly appreciated. Alternativly, if anyone has written routines for dealing with basic ERMapper grids (as opposed to the wavelet compressed data) I'd love to save myself from re-inventing the wheel.

Peer-to-Peer Chat Program
Python seemed like the right choice for writing a peer-to-peer application, as the support for sockets is adequate and the cross-platform ability is nominal. That's why I searched around for P2P frameworks in Python, and didn't have much luck. The framework that I did find was designed specifically for file transfers, rather than simple message carriers, and implemented a complex multicast system. So, with Python in one hand and Google in the other, I set out to write my own P2P app in Python, with zero previous P2P experience. I had to start off by looking up how P2P works, then figure out how to get messages across the network, and then how to bootstrap each node, without centralizing the network. I decided to make it connectionless because they were simple messages. The current implementation is that a peer creates a message and forwards it to all of its known peers, and then the other peers do the same. This is for simplicity, as it causes quite a bit of needless rebound from each of the other peers sending a message which has already been received. In order to reduce this, each message is tagged with a unique ID which is verified against upon each arrival. Once that worked well, I needed to get peers to know each other. My current solution is a provider script running on a single server which is auto-pinged every minute by each peer, and any new peers receive a list of known peers from it. This can easily be expanded to many more servers in case any go offline. Even if zero providers are online, users can manually add nodes from the console and the framework will automatically build a known peer list from them. Like I said, I didn't know anything about P2P before this, and I'm sure much of what I've done so far can be improved upon. That's why I'm posting here. I'd like to make an open request to anyone who would like to assist me in the application development to reduce the resource usage and improve the overall network efficiency. Even simple "Ah, I saw you were doing this in your code, I recommend you do this..." would be of great help. If you are interested, you may view the Google Code page at http://code.google.com/p/kaishi/ or checkout the SVN repository directly using http://kaishi.googlecode.com/svn/trunk/ I have proper hosting and can set up a specific website for collaboration on project ideas and such if support is carried after this message.

For some lists [1], the convention *is* to CC interested parties (which presumably includes the person who's message you are replying to). In the case of Mailman-hosted lists, it would seem to be more considerate to CC folks (since they can opt-out via Mailman), while folks who only follow the list via occasionally reading Gmane [2] will probably appreciate the direct ping.

Flatten an email Message with a non-ASCII body using 8bit CTE
Hello list!
I'm trying to figure out how to flatten a MIMEText message to bytes

I've tried so far:

import email.encoders
from email.charset import Charset
from email.generator import BytesGenerator
from email.mime.text import MIMEText
import sys
body = 'Ζεύς'
encoding = 'utf-8'
charset = Charset(encoding)
charset.body_encoding = email.encoders.encode_7or8bit
message = MIMEText(body, 'plain', encoding)
del message['Content-Transfer-Encoding']
message.set_payload(body, charset)
try:
BytesGenerator(sys.stdout.buffer).flatten(message)
except UnicodeEncodeError as e:
print('error with string input:')
print(e)
message = MIMEText(body, 'plain', encoding)
del message['Content-Transfer-Encoding']
message.set_payload(body.encode(encoding), charset)
try:
BytesGenerator(sys.stdout.buffer).flatten(message)
except TypeError as e:
print('error with byte input:')
print(e)
The `del m[…]; m.set_payload()` bits work around #16324 [1] and should
be orthogonal to the encoding issues. It's possible that #12553 is
trying to address this issue [2,3], but that issue's comments are a
bit vague, so I'm not sure.
The problem with the string payload is that
email.generator.BytesGenerator.write is getting the Unicode string
payload unencoded and trying to encode it as ASCII. It may be
possible to work around this by encoding the payload so that anything
that doesn't encode (using the body charset) to a 7bit value is
replaced with a surrogate escape, but I'm not sure how to do that.
The problem with the byte payload is that _has_surrogates (used in
email.generator.Generator._handle_text and
BytesGenerator._handle_text) chokes on byte input:
TypeError: can't use a string pattern on a bytes-like object
For UTF-8, you can get away with:
message.as_string().encode(message.get_charset().get_output_charset())
because the headers are encoded into 7 bits, so re-encoding them with
UTF-8 is a no-op. However, if the body charset is UTF-16-LE or any
other encoding that remaps 7bit characters, this hack breaks down.
Thoughts?

If Python 3.4 is an option, you can stick to the standard library and use subtests [1].

This is incorrect. GitHub will automatically mark PRs as “Merged” when their tip commit lands in the target branch. I haven't looked up docs for when this landed (if it was even announced), but next to GitHub's “Merge pull request” button there's currently an “or view command line instructions” link which sketches out some command-line Git to accomplish the same thing. But I agree that it's nice to keep the discussion around pull requests somewhere portable.
