I'm trying to create a subclass dictionary that runs extra init code on the first __getitem__ call. However, the performance of __getitem__ is quite important - so I'm trying in the subclassed __getitem__ method to first run some code and then patch in the original dict method for the instance to avoid even the check to see if the init code has been run. Various recipes using instancemethod and the like have failed me. Curiously if __slots__ is not specified no error occurs when setting self.__getitem__ but the function is not overriden. If __slots__ is ['__getitem__'] however it complains that __getitem__ is read only. I do not understand that behavior. -- Zachary Burns (407)590-4814 Aim - Zac256FL Production Engineer (Digital Overlord) Zindagi Games -- http://mail.python.org/mailman/listinfo/python-list Zac Burns 2008-12-03T00:58:36 http://comments.gmane.org/gmane.comp.python.general/600067 This example is right out of python library reference.

The best I could find is some indications that point to 2.5 being the first. I'm asking because we have a Python 2.3.4 runtime for an application that we're now looking into running on Vista.

I often find myself doing the reverse, splitting a list of tuples into several lists, each corresponding to a certain element of each tuple (e.g. matplotlib/pyplot needs those, rather than lists of points). This is of course trivial to do via iteration or listcomps, BUT, I was wondering if there is a function I don't know about that does this nicely? redards /W Andreas Waldenburger 2008-12-02T20:09:30 http://comments.gmane.org/gmane.comp.python.general/600002 my code： −−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−− import base64 def deflashget(st): if st.startswith('Flashget://'): return base64.decodestring(st[len('Flashget://'):])[10:-10] elif st.startswith('http://') or st.startswith('ftp://'): return 'Flashget://' + base64.encodestring('[FLASHGET]' + st +'[FLASHGET]').replace('\n', '') st='Flashget:// W0ZMQVNIR0VUXWh0dHA6Ly9kb3duLnJub3ZlbC5jb20vYm9va3R4dC8zLzEzNjgyLzEzNjgyLnppcFtGTEFTSEdFVF0=&1064' print deflashget(st) −−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−− it's run ,Eric gave me error,the error is "'module' object has no attribute 'decodestring'", what can I do? who can help me? -- http://mail.python.org/mailman/listinfo/python-list ylj798< at >gmail.com 2008-12-02T16:48:16 http://comments.gmane.org/gmane.comp.python.general/600001 http://yeba.pl/show/movies/5257/Perfect_babe_-_Idealna_kobieta -- http://mail.python.org/mailman/listinfo/python-list lolekk1223< at >wp.pl 2008-12-02T15:48:28 http://comments.gmane.org/gmane.comp.python.general/600000 -- http://mail.python.org/mailman/listinfo/python-list B R 2008-12-02T15:19:35 http://comments.gmane.org/gmane.comp.python.general/599994 I need help ... I've been looking at this every evening for over a week now. I'd like to see my kids again! I have script that runs fine in the terminal but when I try to run it in a crontab for either myself or root, it bails out. The trouble is that obviously I get no console when using crontab so can't see any traceback. I use logging which shows 'info' messages as the script is working, but no error messages. I've peppered it with debug messages to try to track it down to a line, but it stops it the middle of appending data to a list. I'd expect it to bail out when calling a module or reading/writing to a different file. Is there any way of getting more info from the app, like popping up a console while its running? my crontab is: 30 15 * * * cd /home/myusername/src && python myscript.py ALJ -- http://mail.python.org/mailman/listinfo/python-list Astley Le Jasper 2008-12-02T14:35:58 http://comments.gmane.org/gmane.comp.python.general/599991 Hi everybody, I do this: [5, 6, 3, 8] Is there a quicker way to do this?

I'm going to read in an Ascii file containing float numbers in rows and columns (say 10 columns 500000 rows) for further numerical process. Which format is best to save them in, eg, dictionary, list, or numpy array when it comes to performance? Will it be beneficial to convert all strings to float directly after reading or it doesn't matter to save them as string and thereafter when it comes to calculation convert them to floats?

The American people are still waiting for a copy of Obama's original birth certificate that includes all his birth information. Remind your US presidential electors of their constitutional duty to investigate Obama's natural-born citizen status. No federal agency like FBI or Secret Service, no Hawaii bureaucrats have ever investigated Obama's birth in Hawaii. Many illegal aliens in USA have official "birth certificates" issued by state bureaucrats on the basis of falsified birth records. Obama has spent over $800,000 in legal costs to avoid presenting a $10 copy of his original birth certificate on the grounds that nobody has a legal standing to see it. Remind your US presidential electors that they have the legal standing and constitutional duty to investigate Obama's birth in Hawaii by demanding that Obama provide all his original birth records, and a federal agency like FBI or Secret Service fully investigate them. To find the names of US presidential electors use the partial list at wikipedia below. Or use www.google.com, click News on top, then in the Search News enter the name of your state and the words: presidential electors. Or contact your US Senators, US House Rep, your state senators/reps, etc. If a US presidential elector refuses to investigate Obama's eligibility then post his/her full name on the internet so that all web search engines can pick it up. http://www.wnd.com/index.php?fa=PAGE.view&pageId=81550 http://en.wikipedia.org/wiki/List_of_United_States_presidential_electors,_2008 http://www.senate.gov/general/contact_information/senators_cfm.cfm http://clerk.house.gov/member_info/index.html -- http://mail.python.org/mailman/listinfo/python-list girbarobert< at >yahoo.com 2008-12-02T10:34:34 http://comments.gmane.org/gmane.comp.python.general/599973 ________________________________________________________________________ ANNOUNCING eGenix.com mxODBC Connect Python Database Interface Version 1.0.0 Our new client-server product for connecting Python applications to relational databases - from all major platforms This announcement is also available on our web-site for online reading: http://www.egenix.com/company/news/eGenix-mxODBC-Connect-1.0.0-GA.html ________________________________________________________________________ INTRODUCTION The mxODBC Connect Database Interface for Python allows users to easily connect Python applications to all major databases on the market today in a highly portable and convenient way. Unlike our mxODBC Python extension, mxODBC Connect is designed as client-server application, so you no longer need to find production quality ODBC drivers for all the platforms you target with your Python application. Instead you use an easy to install Python client library which connects directly to the mxODBC Connect database server over the network. This makes mxODBC Connect the ideal basis for writing cross-platform database programs and utilities in Python, especially if you run applications that need to communicate with databases such as MS SQL Server and MS Access, Oracle Database, IBM DB2 and Informix, Sybase ASE and Sybase Anywhere, MySQL, PostgreSQL, SAP MaxDB and many more, that run on Windows or Linux machines. By removing the need to install and configure ODBC drivers on the client side, mxODBC Connect greatly simplifies setup and configuration of database driven client applications, while at the same time making the network communication between client and database server more efficient and more secure. For more information, please see the product page: http://www.egenix.com/products/python/mxODBCConnect/ ________________________________________________________________________ NEWS mxODBC Connect 1.0.0 is the first general availability release of our new mxODBC Connect product. With this release we have further improved the performance and round-trip times of the mxODBC Connect network layer even more. We are now able to achieve a *more than 10 times better performance* for a typical multi-tier application that runs on Linux and connects to a MS SQL Server database running on a Windows host, compared to the same application using mxODBC and the FreeTDS ODBC driver. Thanks to everyone who participated in the public beta ! ________________________________________________________________________ DOWNLOADS The download archives as well as instructions for installation and configuration of the product can be found on the product page: http://www.egenix.com/products/python/mxODBCConnect/ Evaluation licenses for the server part are available free of charge: http://www.egenix.com/products/python/mxODBCConnect/#Evaluation The client part of mxODBC Connect is always free of charge. _______________________________________________________________________ SUPPORT Commercial support for this product is available from eGenix.com.

A shell script runs my python script several times, each time with different paramters. E.g. # cat foo.sh # Lot of setup stuff ${TEST_DIR}/bin/run-test.py --arg1 foo1 --arg2 bar1 --arg3 baz1 ${TEST_DIR}/bin/run-test.py --arg1 foo2 --arg2 bar2 --arg3 baz2 ${TEST_DIR}/bin/run-test.py --arg1 foo3 --arg2 bar3 --arg3 baz3 There is a delay of about 10-15 seconds before run-test.py starts executing. Can someone suggest a method to speed up this process? Most of the delay seems to be due to python loading up the required modules. Is it possible to load all the modules used by run-test.py in a pre-execution environment in order to prevent this delay? I considered a rewrite of the shell script into python, but it has too many dependencies on shell libraries and I don't want to go that route (unless an alternative solution is impossible).
