Europython 2012 - Early Bird will end in 3 days!
Hi all, the end of Early bird is on May 2nd, 23:59:59 CEST. We'd like to ask to you to forward this post to anyone that you feel may be interested. We have an amazing lineup of tutorials and talks. We have some excellent keynote speakers and Guido will be with us! [https://ep2012.europython.eu/p3/whos-coming?speaker=on#guido-van- rossum] If you plan to attend, you could save quite a bit on registration fees ... but remember that early bird registration ends in 3 days! Things to Remember: - House your server: We will be running an Intranet at EuroPython, to let sponsors, startups, open-source projects and speakers showcase their products directly within our network. - Training: You can book the trainings you want to attend, directly from the schedule (click on the training, and then click on the "Book" button). - Sprints: Wonderful hacking sessions during the weekend, learn from expert Python developers, and contribute to the Python ecosystem! - Probably we've already discussed about the fact that Guido Van Rossum will be at Europython in Florence :) ---> Register Now! - https://ep2012.europython.eu/p3/cart/ All the Best, -- http://mail.python.org/mailman/listinfo/python-list

I mean Element 1,1 = 2.81e14 in Python, but something like 3e14 in Matlab and so forth - there's a small difference in the results... Both results are *wrong*: no inverse exists. What's the best solution of the two wrong ones? Best least-squares solution or whatever? Trust me. They're both so wrong that it doesn't matter. Have a look at A*inv(A) and inv(A)*A and you'll see by yourself. With python, I would also kindly ask about how to avoid this problem in the future, I mean, this maybe means that I have to check the condition number at all times before doing anything at all ? How to do that? If cond(A) is high, you're trying to solve your problem the wrong way. So you're saying that in another language (python) I should check the condition number, before solving anything? Yes, unless you already know that it will always be low by design. You should try to avoid matrix inversion altogether if that's the case. For instance you shouldn't invert a matrix just to solve a linear system. What then? Look at the documentation of the library you're using. Cramer's rule? Surprisingly, yes. That's an option. See "A condensation-based application of Cramerʼs rule for solving large-scale linear systems" Popular linear codes are based on Gaussian elimination or some iterative method, though.

Less than 100 can be good in general, but I really can't give you a fixed number to use, as I am not an expert in this subjects, others who know more about it might have better recommendations. Alas, there's no fixed number and as if that wasn't enough, there are many condition numbers, each one with different properties. For instance, the Skeel condition number is scale-invariant and it's useful when a matrix is ill-conditioned just because its rows are out of scale.

Creating a directory structure and modifying files automatically in Python
Hi, I would like to automate the following task under Linux. I need to create a set of directories such as 075 095 100 125 The directory names may be read from a text file foobar, which also contains a number corresponding to each dir, like this: 075 1.818 095 2.181 100 2.579 125 3.019 In each directory I must copy a text file input.in. This file contains two lines which need to be edited: . . . foo = 1.5 !edit me.. . . . bar = 1.5 !..and me, too . . The number after the "=" must be set to the value given in foobar for the corresponding directory I thought to write a bash/awk shell script for this. However, if and when the script works, I'll probably start to add more features in order to automate even more tasks. It seems to me that Python or perl would be better suited to write a larger, mantainable script. Unfortunately, I know neither of them. Could you show me how to write the script in Python?

Trouble splitting strings with consecutive delimiters
I'm using regular expressions to split a string using multiple delimiters.
But if two or more of my delimiters occur next to each other in the
string, it puts an empty string in the resulting list. For example:
re.split(':|;|px', "width:150px;height:50px;float:right")
Results in
['width', '150', '', 'height', '50', '', 'float', 'right']
Is there any way to avoid getting '' in my list without adding px; as a
delimiter?

Sort comparison
A while back I did a sort algorithm runtime comparison for a variety of sorting algorithms, and then mostly sat on it. Recently, I got into a discussion with someone on stackoverflow about the running time of radix sort. I realize it's commonly said that radixsort is n*k rather than n*log(n). I've been making that case that in real life, frequently k==log(n). Anyway, here's the comparison, with code and graph: http://stromberg.dnsalias.org/~strombrg/sort-comparison/ (It's done in Pure python and Cython, with a little m4). Interesting, BTW, that an unstable quicksort in Cython was approaching timsort as a C extension module in performance, even though timsort in Cython wasn't that performant. It makes one wonder if a highly optimized quicksort as a C extension module wouldn't outperform timsort in the standard library. Yes, I know, we've committed to keeping list_.sort() stable now, and quicksort normally isn't stable. Also, before timsort, did CPython use quicksort? I'd be a little surprised if it hadn't, since people used to say quicksort was the best thing around in practice. -- http://mail.python.org/mailman/listinfo/python-list

You could use a sequence of such delimiters.
>>> re.split('(?::|;|px)+', "width:150px;height:50px;float:right")
['width', '150', 'height', '50', 'float', 'right']
Consider splitting twice instead: first into key-value substrings at
semicolons, and those into key-value pairs at colons. Here as a dict.
Better handle the units after that.
>>> dict(kv.split(':') for kv in
>>> "width:150px;height:50px;float:right".split(';'))
{'width': '150px', 'float': 'right', 'height': '50px'}
You might also want to accept whitespace as part of the delimiters.
(There might be a parser for such data formats somewhere in the
library already. CSV?)

I am also coming to the conclusion that Google Groups is no longer fit-for-purpose. Ironically, here are two replies that I can see in Outlook Express, but do not appear in Google Groups. Reply from Benjamin Kaplan - > I believe the mail-to-news gateway has trouble with HTML messages. Try > sending everything as plain text and see if that works. I checked, and all my posts were sent in plain text. Reply from Terry Reedy - > Read and post through news.gmane.org I have had a look at this before, but there is one thing that Google Groups does that no other reader seems to do, and that is that messages are sorted according to thread-activity, not original posting date. This makes it easy to see what has changed since the last time I checked. All the other ones I have looked at - Outlook Express, Thunderbird, and gmane.org, sort by original posting date, so I have to go backwards to see if any threads have had any new postings. Maybe there is a setting that I am not aware of. Can anyone enlighten me? Thanks Frank -- http://mail.python.org/mailman/listinfo/python-list
