Themed TK (tk Tile) at last?!
Looks like we finally get tkinter GUI based programs according to Issue# 2983 in Python 3.1a so our programs don't look like something out of early 1980's and can be themed to more closely match the underlying Operating Systems widget set! This is a big deal in that while tkinter came with (just about) every Python the desire to use wxWidgets or Qt etc was high because tkinter widgets just look so horrid. Now for simple GUIs you can use a themed widget set. ttk or themed tk won out as the name, others may remember tk tile. The Python 3.1a web page still had what's new in Python 2.7 on the web page so does this also enter the Python 2.x branch? I don't know yet. But it so I might have a push to move off of 2.5.4 finally for the so simple GUi based apps I have. Good job python-dev team. Cheers, PN -- http://mail.python.org/mailman/listinfo/python-list
Re: should i move on to python3
Maybe if everyone shares their own thinking for their own situations it may help. I know the 2.x branch rather well, and cut my teeth on it. My work involves x509 cryptographic materials and I cut my own binaries and then wrap them in python to extend and enhance or build a lot of automation around the binaries. I am the primary consumer of the final programs so I don't wrap them in any sort of GUI. As such my python touchpoints are rather slim on libraries. It took me all my life up to a month ago to move off of os.popen and onto subprocess. With this I could move between Python branches without much issue. I do have an Ubuntu system at work as well as Windows so I'm a lazy sod who didn't feel like building a custom Python build so I jus use what comes with Ubuntu. Because of this I am stuck with a tenuous small reliance on the 2.x branch, very small but add in lazy or not wanting to use up xyz hours preparing new environments and learning a new idioms and you might get the typical python user who encorporates it at a job function where programming is not their job function but they use python to help make the job eaier in a few areas. I use more 3rd party modules at home and use the OS X platform exclusively there. I wish I had time with the family but a lot of my projects have been left by the wayside (web page scraping, games and opengl programming, etc). Unlike Windows, tkinter GUI programs on OS X could look native-ish. I always have aversions to making GUI programs for distribution that require users install large dependencies so I have shied away from doing them. With 3.1 it looks like themed tk support is now added so that could be an incentive. That and I silently troll python submitters and got the feeling 3.1 was what 3.0 was supposed to be ;-) so I been silently waking for 3.1 to go final before spending time with the 3 branch to learn the changes. In short if it's just you using your programs you have a lot of flexibility in your choice of branch to use. If you distribute then you are restricted by your end user branch sets even more. If you heavily use 3rd party modules you are tied down further. So work backwards and decide what is it you at writting, what features internal and external are you using or desire to use and who will consume your program. Then you'll have your answer or pretty close to it. Cheers, PN On 08/03/2009, Martin P. Hellwig x...@xs4all.nl wrote: R.

f you have ever looked at your Mac’s root directory and wondered what
some of those other directories are for, you’re probably not alone.
Mac OS got a whole lot more complex with the advent of OS X, adapting
a unix file structure from Free BSD Unix that is largely unfamiliar to
Mac OS 9 and Windows users. So just what is /System, /Library, /usr,
and all the others for anyway? Here’s a brief explanation of each
directory as found in Mac OS X.
By default, if you look in the root of your Mac’s hard disk you’ll see
some unfamiliar sounding directories. From the command line, you will
see even more if you type ls /. Explained in no particular order:
/Applications = Self explanatory, this is where your Mac’s applications are
kept
/Developer =The Developer directory appears only if you have
installed Apple’s Developer Tools, and no surprise, contains developer
related tools, documentation, and files.
/Library = Shared libraries, files necessary for the operating system
to function properly, including settings, preferences, and other
necessities (note: you also have a Libraries folder in your home
directory, which holds files specific to that user).
/Network = largely self explanatory, network related devices, servers,
libraries, etc
/System = System related files, libraries, preferences, critical for
the proper function of Mac OS X
/Users = All user accounts on the machine and their accompanying
unique files, settings, etc. Much like /home in Linux
/Volumes = Mounted devices and volumes, either virtual or real, such
as hard disks, CD’s, DVD’s, DMG mounts, etc
/ = Root directory, present on virtually all UNIX based file systems.
Parent directory of all other files
/bin = Essential common binaries, holds files and programs needed to
boot the operating system and run properly
/etc = Machine local system configuration, holds administrative,
configuration, and other system files
/dev = Device files, all files that represent peripheral devices
including keyboards, mice, trackpads, etc
/usr = Second major hierarchy, includes subdirectories that contain
information, configuration files, and other essentials used by the
operating system
/sbin = Essential system binaries, contains utilities for system administration
/tmp = Temporary files, caches, etc
/var = Variable data, contains files whose contents change as the
operating system runs

Re: PYTHONPATH on Mac 10.5
+1 for site packages and standard shebang, still lets you launch with

also for some clues, just open up a terminal in your Mac OS X computer
and check out your exports your PATH will be different depending on
all the software and development environments you may or may not be
using on your Mac, in particular:
declare -x

declare -x PYTHONSTARTUP=/Users/pythonnutter/.pythonstartup
for the ultra curious, my custom python startup:
$cat .pythonstartup
# python startup file

import os
# tab completion
readline.parse_and_bind('tab: complete')
# history file
histfile = os.path.join(os.environ['HOME'], '.pythonhistory')
try:
readline.read_history_file(histfile)
except IOError:
pass
atexit.register(readline.write_history_file, histfile)
del os, histfile, readline, rlcompleter
On Windows you don't have much control in standard batch files but the
way I keep my Windows box (at work mind you, none at home)
multi-python'd
is I configure the environment for Framework 2.5.4, and all the path
environment variables are configured for the standard directory and
the scripts subdirectory.
in 25's scripts is go26.bat which just pre-pends the 2.6.1 path on the
head of PATH, and of course a go3.bat that pre-pends in 3.0.1
if you want to get fancy, since there is no pop in batch files that I
know of, you could drop a .py script in to read in PATH, pop off two
entries and modify the environment PATH so you fall back down the tree
(might need some list reversing in there to finish the massaging for
pops)
most times I get by with just exiting the terminal session in windows
and a new cmd session will once again take on the defaults for 2.5.4

Re: Found a very nice, small, cross-platform GUI toolkit for Python.
Note: spelling is OcempGUI. Also, since google broke some of the links, here's that main link again: Thats my bad or more to the point my iPhone bad, typing fast with spellcheck changes words to real dictionary words. Well, to be fair, SDL is pretty commonly-used software and they offer binary downloads for Mac OS X and MS Windows. Pygame seems to provide the same. So, installation should be a breeze. Not on Mac. To get SDL, PyObjC, PyGame and other dependencies installed on the platform you are talking on downloading and installing close to 50MB+ of packages before you get to the point where you install the OcempGUI package. Thats a lot to ask of a user just to run my one program on their system. If it was just myself and I wanted to go through the process for educational/self-benefit I wouldn't mind. But TkInter is already installed (0 dependencies) and on every Mac out there so when I said 87Kbytes for a widget set that looks rather Mac like I was saying compare 87Kbytes to 50+Megabytes to get a GUI for my python application. Along the same lines on my Linux boxes, GDK+/KDE are normally already installed, nothing for the entire user base to install additional or very little (additional) dependencies to install to get a wxWidget or Qt interface going on those systems. Python wrappers are small but the additional dependency installs above and beyond the base system is what I am pointing at as killing off any interest in OcempGUI. I also have this sneaking suspicion that the BDFL is secretly on the sidelines waiting for the Tk tile theming engine to mature as if it does and becomes standard in Python distributions I would say the justification for learning wx and qt would be diminished by an unknown quantity. What? Qt and wX are *huge* compared to OcempGUI. -- http://mail.python.org/mailman/listinfo/python-list

Re: Found a very nice, small, cross-platform GUI toolkit for Python.
Had a look and it is still under my radar unfortunately because of TkInter. OceanGUI has a lot of large decencies (Pygame, SDL libraries, PyObjC, etc.) to install on my system to just to get a GUI thats no better loking than TkInter which comes pre-installed (no dependencies) on most every major platform. If I was writing a game I might be interested, but I'd want to do some serious skinning of that GUI to make it look better. For applications installing the full wxWidgets or Qt toolkits would be less disk space and dependcies than OceanGUI and performance would probably be higher. TkInter also has many skins/themes you can add that makes it rather, although not 100% native looking on target systems. For example, check out http://tclmacbag.autons.net/screenshots.phtml For 86K download/dependencies I can get a rather Mac looking GUI. Cheers, PN 2009/2/16 laplacia...@gmail.com: I think I just found the GUI toolkit for Python I've been searching for. It seems to meet all of the following requirements: * free software * small (I don't need batteries -- Python already comes with those.) * easy to use * actively maintained * cross-platform * easy to install * based on a stable and actively-maintained C library * does not depend on an external scripting language (for example, Tcl) * well-documented * not too many dependencies * can easily integrate with PyOpenGL * support for accessibility and it's also written in Python.

Re: Integrating awk in Python
If you or anyone who reads the thread is interested in using Python in
an advanced way you use generators and build processing chains that
will take the performance of Python to the edge and even give old AWK
a run for its money for certain types of processing.
Python:
wwwlog = open(access-log)
bytecolumn = (line.rsplit(None,1)[1] for line in wwwlog)
bytes = (int(x) for x in bytecolumn if x != '-')
print Total, sum(bytes)
Python execution time: 25.96 seconds
AWK:
% awk '{ total += $NF } END { print total }' big-access-log
AWK execution time: 37.33 seconds
With generators you can plug in filters at any stage:
lines = lines_from_dir(big-access-log,.)
lines = (line for line in lines if 'robots.txt' in line)
log = apache_log(lines)
addrs = set(r['host'] for r in log)the beauty of generators is that
you can plug
filters in at almost any stage
The second line increased the execution time of a 1.3GB log file.
Without it the execution was shameful at 53 minutes
With the second line added execution time was 93 seconds
David Beazley presented a great talk and accompanying PDF at
PyCon'2008. It would be great if these generator tricks / patterns
came more to the focus of the commuinity.

Hello,
I'm developing a software package using python. I've programmed all
necessary tools but I have to use other stuff from other people. Most of
these external scripts are developed using awk.
At the beggining I thought to translate them and program them in python
but I prefer to avoid it because it means a lot of work and I should do it
after each new version of this external stuff. I would like to integrate
them into my python code.
I know I can call them using the system environment but it is slower than if
I call them inside the package. I know it is possible with C, do you have
experience on integrate awk into python calling these awk scripts from
python?
Thanks in advance!

Re: SSL certificate parsing?
If no one answers, the way I do my work with certificates is I just wrap OpenSSL myself by doing a popen call (probably now should be using subprocess for any future scripts I write). I then redirect the output that normally goes to the shell window into a buffer then I search/slice out the fields using standard Python string searching. You could go to regex's but its overkill in my opinion if you can simply do standard string searches. The buffer always follows a set pattern so you are not going to have to search wildly varying output from OpenSSL call to OpenSSL call. I looked at PyOpenSSL but I have country specific OIDs that are standard by not in the default ISO standard. Most libraries fall short on supporting what I need and it was brain dead easy to just call OpenSSL in my script directly and capture the output for parsing. Its up to you what you want to do with the extracted information, you could just populate a dict with it and perhaps shelve or store it for later use if you have such a need or as in my case since I only process the certificates once I just use the parsed information immediately in my scripts logic decision tree(s) to create various output. Cheers, PN 2009/1/5 Taras Ivashchenko naplan...@gmail.com: Hello, list! I use pyopenssl [0] for checking SSL certificates. And one of such checks is if given certificate is self-signed.

These combine to give you easy ways to do many things you might otherwise do with REs. I agree, I'm going through the new book Python for Unix and Linux Administration now and although in general I like what they say, they take you through the built in string functions and then introduce REs and end the chapter leaving the reader with the impression that REs are the better solution and I only agree with the case of the problem/program they presented.

This intermediate use of string built-in functions was missing between the first string-function and RE versions of code and imho it is not letting the readers see that string-functions are even more powerful than the reader is lead to believe and that REs are pushed more towards edge cases than the impression the reader seems to be left with which is to use REs more. At least if you push REs inform the readers where to get the a RE GUI builder written in Python so they can build and *test* the complex and unwieldy REs to perform anything beyond the basic pattern searches.

Python on iPhone actually rather good
Mini install guide for python on the iPhone: Cydia = Install SSH helps make initial configuration easier until you get used to MobileTerminal Cydia = Install MobileTerminal (closest to a bash shell you get on your iPhone currently) Cydia = Install Finder (graphical alternative to using SSH/MobileTerminal for setting permissions, navigating file system, moving/copying files, etc.) Cydia = Install Python (currently installs CPython 2.5.1) Cydia = Install PyObjC (this is your hook into iPhone API) Cydia = Install Setuptools (currently install 0.6c7) Cydia = Install iPhone/Python (examples, the hello world is a PyObjC call into the iPhone API to load and scroll the contacts list in the phone) Not much left to have a fast running python implementation in your pocket except IMHO ipython. Now that you have Setuptools installed, you can run easy_install directly on your iPhone and download iPython over the air. The iPhone OS X architecture is of course a BSD Unix Userland environment so you should feel right at home. The two accounts, root and mobile both share the same default password 'alpine'. So once you setup your phone I recommend you change the password for each account right away just to secure your phone a little more. Root you won't need, Mobile is what the default account is on the current iPhone OS implementation for the standard user (you). Easiest way to access your phone is SSH from your Mac, Linux, or Windows box. (or just use MobileTerminal.app on the iphone directly keeping in mind you will default to the mobile account in the shell) Simply join your iPhone over wifi to your wireless access point or ad-hoc-network, and display your iPhone's ip address. Now you are ready to ssh into it. $ssh root@your iphones ip address password: alpine $chpass change your password for root while you are here might as well install ipython $easy_install ipython $exit now same for mobile $ssh root@your iphone ip address password: alpine $chpass change your password for mobile $ipython test your ipython if it loads, yes? good. now just exit() $cd .ipython $nano ipy_user_conf.py or vi or emac or whatever you like, its easier for beginners to try nano CTRL+W (find) Where: #import ipy_editors Now for those who are following along using MobileTerminal.app here is a quick guesture routine Single Tap screen to bring up a quick tap box grid of common unix commands that get pasted when selected into the shell Double Tap screen to hide the onscreen keyboard and see the full screen. Drag Top left downward diagonally to right for CTRL Drag Top right downward diagonally to left for TAB -- good for tab completion in the bash shell ok back to editing ipy_user_conf.py Delete the # comment character Scroll down MobileTerminal.app users just drag up, down, left, or right quickly for cursor movement Add your new line below the text # Or roll your own ipy_editors.install_editors(nano +$line $file) CTRL+X (exit) Y to save Now test your ipython link to nano editor $ipython In [1]: edit test.py nano should now launch and you can edit your python script on your iPhone directly, when you save it, iPython will execute the python code In [2]: exit() $cat test.py your code should display, good now we are done $rm test.py remove our test file Its up to you where you want to save your python scripts. I would suggest in Documents under your account (mobile). for example launch MobileTermina.app $cd ~ $cd D* or just D and try the tab completion gesture Top right drag diagonally down to left $mkdir python or whatever you want to call your directory What is missing? Tkinter, iPhone uses its own API, Desktop Manager (Springboard), etc. What is different? PyObjC, this is where you get to use those iPhone API calls from within your python script on the iPhone including GUI API calls. Now you have Python in your Pocket that you can take anywhere and whip it out anytime the Python bug hits you and you want to work on some code. You can use SSH to move/copy/sync your files to your desktop. Or other ways: AirSharing app over wifi, etc. I'll be giving iPhone Python 2.5.1 a workout on on of Mark Lutz's books and report any more gotchas that I come across.

Re: Python certification
Yeah. The day Python goes Certification required to get a job is the day I quit Python forever and move on to another language. Certification prooves you're an idiot who needs to spend money to work for another idiot who doesn't know enough about programming to know if they hire competent programmers and need an idiot paper to make them feel better and sleep better at night. 2008/10/18 Lawrence D'Oliveiro [EMAIL PROTECTED]: In message [EMAIL PROTECTED], Ben Finney wrote: srinivasan srinivas [EMAIL PROTECTED] writes: I m planning to do certification in Python??

Re: Python for the iPhone?
Yes it does involve Jailbreaking. Python GCC Java and Ruby are all available to run on the iPhone after you Jailbreak it. Just run the Cydia appliacation (jailbreak's AppStore) to install anything you want. For me I have not installed Python (yet). Jailbreak was only to tether iPhone to my Macbook since I've moved house and living out of a hotel until move into my next house. I would never have jailbroken if Apple did not killswitch the NetShare application. Tethering is 100% legal in my country and Apple just lost me in only 2 weeks of iPhone ownership. Cydia - OpenSSH. Then I just reverse ssh socks proxied into my iPhone and shazam. Internet access here I am. (Downloading all my Mac updates as I type).

Re: An FTP Client...My first real program!
ery low level and not very useful for beginners as a lot of the heavy
lifting and management is still left up to you, the programmer.
The module ftputil is a high-level interface to the ftplib module. The
FTPHost objects generated from it allow many operations similar to
those of os and os.path. An example:
# download some files from the login directory
host = ftputil.FTPHost('ftp.domain.com', 'user', 'secret')
names = host.listdir(host.curdir)
for name in names:
if host.path.isfile(name):
host.download(name, name, 'b') # remote, local, binary mode
# make a new directory and copy a remote file into it
host.mkdir('newdir')
source = host.file('index.html', 'r') # file-like object
target = host.file('newdir/index.html', 'w') # file-like object
host.copyfileobj(source, target) # similar to shutil.copyfileobj
source.close()
target.close()
Now if you are again purely in it for a challenge or for and
educational roller coaster ride, ignore the suggestion to look at
higher level ftp modules =)

Re: Any Game Developers here?
I used to use PyGame but the horrible delay waiting for OS X binaries put me off. I now use Pyglet extensively, and combine Pyglet + Rabbyt to get amazing sprite handling speeds. Pyglet/Rabbyt make use of OpenGL which comes installed on all the major systems out there. PyGame requires the installation of the SDL library to work so is a lot larger installation requirement. There are two books I know of currently in print on game programming, both use PyGame as it was out first. One book is horrible and only worth for cleaning yourself up after you use the bathroom. The second is really well written (The L express game programming book) and highly recommended if you need to get some basic game design and programming under your belt in Python. That said its stupidly easy to port examples to work on Pyglet/Rabbyt so you won't do yourself a dis-service if you want to buy the book but want to develop later in Pyglet/Rabbyt. Cheers, PN P.S. Since you've likely found Pyglet and PyGame already, the only other reference URL you need is for Rabbyt so go here for that: http://matthewmarshall.org/projects/rabbyt/ 2008/7/19 Michael Lubker [EMAIL PROTECTED]: Any people that use Python as the predominant language for their game development here? ~Michael -- http://mail.python.org/mailman/listinfo/python-list -- http://mail.python.org/mailman/listinfo/python-list

PS. To see some real games developed under pressure/time constraints in Python you should visit PyWeek to see what individuals and teams can create in only a weeks time! http://pyweek.org/ 2008/7/19 Michael Lubker [EMAIL PROTECTED]: Any people that use Python as the predominant language for their game development here? ~Michael -- http://mail.python.org/mailman/listinfo/python-list -- http://mail.python.org/mailman/listinfo/python-list
Re: Best Python packages?
I think the hidden gems in multimedia/game production are Pyglet and Rabbyt. Whereas PyGame is the older api, its large and bloated and has of course a heavy dependency on SDL. Pyglet and Rabbyt are lightweight, efficient, have some amazing functions and hit native OpenGL in all the major OS distributions and Bruce The Presentation Tool utilizes the former to take on MS PowerPoint to show what you can do besides games =) Pyglet: http://pyglet.org/ Rabbyt: http://matthewmarshall.org/projects/rabbyt/ Bruce The Presentation Tool: http://code.google.com/p/bruce-tpt/ Cheers, PN In the original post you asked for hidden gems and now it seems you just want to know about Madonna or Justin Timberlake.

Re: Freesoftware for auto/intelligent code completing in Python
If you guys can get your head out of IDE land, you'll find iPython does a fantastic job at introspection and Auto-completion, you can launch shell commands and editors and when done saving be back in the iPython shell, save memory/variable space to disk so you can come back the next day and continue off where you were. It puts IDEs to shame. If you can't get your Windows-centric IDE need eliminated, then Wing IDE 101 will not auto-complete, its been deliberately disabled to force students (hence 101) to memorize python/function names. Komodo Edit is a free download and will Auto-complete. Cheers, PN -- http://mail.python.org/mailman/listinfo/python-list
