Re: [Tutor] Hoping to benefit from someone's experience...
just a thought ... there must be some way of using OpenOffice to convert your ORIGINAL word documents into HTML files ... then as html is a very nice structured language that you can manipulate modify with ease just by adding some tags inside where you want or wish this is also only if you have some rich content like tables inside your documents ... if thats not your case, you can use OpenOffice tou extract just text ... hope this helps ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor

Re: [Tutor] Nested dictionary with defaultdict
Kepala Pening wrote:
count = lambda x: [{y: x.count(y)} for y in set(x)]
At least for long enough lists, this is likely to be more expensive than
the approach using defaultdict. Your count() function iterates the list
(1+m) times, where m is the number of distinct words - once to create
the set, and once for each call to x.count(). The complexity of your
count() is O(m*n) where n is len(x).
OTOH the defaultdict method is O(n). The loops in your solution are all
in C code which may give some performance improvement but I expect that
would be overshadowed by the factor of m as m and n get large.

It's a rounding error.

y represents midnight on the given date.

So y-n is a fractional day, not a whole day.

The -i flag in particular might conflict with Pythons own -i option.
I tried with raw_input but that only works in idle.
What makes you think that?
raw_input is the normal way to get input from stdin.
Can you explain what you did and what the result was?
Perhaps with a short code example?
Try this for example:
name = raw_input('What's your name? ')
print hello, name
That can be run in IDLE or in a command window
or using file redirection as described above.
Tell us how you get on...

[Tutor] Best practice for installing new packages (eggs)
I would like to take a look at the wxOptParse package. This is my first time installing a package (vs. a module) so I'm looking for feedback on what installation technique I should use and where (in terms of folder paths) one would normally install 3rd party packages. For example, is are there conventions for where to put core packages, experimental packages, and packages that one is building themselves? Also, is it safe to assume that installing a 3rd party package won't (unexpectedly) affect other parts of my Python environment. I'm running Python 2.5.2 on Windows XP Pro SP2. Here are the 3 installation options that wxOptParse provides: snip Choose one of the following methods. In all cases you probably need to run as root. Egg Download # easy_install.py wxoptparse Egg File - # easy_install.py wxOptParse-x.y.z-py2.4.egg Easy Install Zip # easy_install.py wxOptParse-x.y.z.zip Normal Python Install -- # unzip wxOptParse-x.y.z.zip # cd wxOptParse-x.y.z # python setup.py install Also note the following run instructions: If you want to run your program you should be able to type: wxoptparse myprogram.py Under Windows you may need to add c:\Python2.4\scripts to your path (or whatever directory python is installed) in order to run wxoptparse. The standard Python installer does not appear to do this for you. /snip Thank you! Malcolm ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor

First, there are two obvious indentation errors you can find yourself. This may be a byproduct of having pasted your program into an email. Email programs will often incorrectly reformat Python code so that the indentation no longer works. To send long code listings to an email list, use a pastebin like: http://python.pastebin.com/ and send us the link of your pasted code.

[Tutor] Need suggestion / advice - controlling remote server
Hi all, I am after some advice / suggestions. I have written web interface for viewing CCTV images http://code.google.com/p/kmotion/wiki/ScreenShots its called 'kmotion'. Underneath its all Python daemons. It usually runs stand alone on headless servers. Now I am about to write a KDE interface in Python QT4 for config local viewing. The question is how to communicate with the remote kmotion servers Python daemons. I could access the images via port 80, no prob but I need the KDE interface to change configs etc and restart services. I am thinking of getting the KDE interface to ssh in and do the changes via shell commands, ie change config files, restarts deamons etc, should work OK. Is this acceptable ? How would you guys do it ? Thanks in advance Dave -- Please avoid sending me Word or PowerPoint attachments.

Restarts are probably the trickiest becauyse you need to be able to pick up again with the admin interface after the restart. But its not that tricky. ...getting the KDE interface to ssh in and do the changes That will work too, but a web admin is probably easier for users since you don't need to maintain a thick client on the desktop.

[Tutor] web programming tutorials?
[I thought I sent a similar msg to this list 2 days ago, but now I'm not sure it went through, so sorry if I've doubled] Can someone point me to a start-from-dead-scratch tutorial about the basics of web programming? I've been learning wxPython for GUI programming, but web programming (that is, making web applications) seems like another world entirely. I'm aware of *names*--Django, Pylons, CherryPy, TurboGears, Zope, Webpy, etc.--but I have a poor sense of what all this means, and so I am sort of 'pre-Python' in my understanding. I've scanned the archives of this list, but so far haven't found pointers to tutorials that assume very little knowledge. I was kind of hoping Alan Gauld's project would be updated for the tempting but not yet existent section on web programming. Any word on that, Alan? In lieu of that, can anyone recommend books/online tutorials/words of advice? Thanks, Che _ Pack up or back up–use SkyDrive to transfer files or keep extra copies.
