Re: More About Unicode in Python 2 and 3
Chris A wrote: I'm not sure that there is an easy way. See, here's the deal. If all your data is ASCII, you can shut your eyes to the difference between bytes and text and Python 2 will work perfectly for you. Then some day you'll get a non-ASCII character come up (or maybe you'll get all of Latin-1 for free and it's when you get a non-Latin-1 character - same difference), and you start throwing in encode() and decode() calls in places. But you feel like you're fixing little problems with little solutions, so it's no big deal. Making the switch to Python 3 forces you to distinguish bytes from text, even when that text is all ASCII. Suddenly that's a huge job, a huge change through all your code, and it's all because of this switch to Python 3. The fact that you then get the entire Unicode range for free doesn't comfort people who are dealing with URLs and are I think this is important because this kind of programming, working with urls is so common and so important. whEther anyone like's it or not, python 3 makes itch harder to do this very crucial kind of programming.

Re: More About Unicode in Python 2 and 3
I'm so sorry for the mess in my post above, I apologize to all, I accidentally hit return ... I just meant to say that internet programming using ASCII urls is so common and important that it hurts that Python 3 makes it so much harder. It sure would be great if Python 3 could be improved to allow such programming to be done using ASCII urls without requiring all the unicode overhead. Armin is right.

Paul Boddie wrote: The figures behind the scenes are quite enlightening for that particular page. If you (or community experiences) don't agree with the rankings (wxPython apparently even easier to learn than PythonCard and Tinder, a bunch of Gtk-based toolkits having more or less full Linux scores) then you'll have some surprises, I'm sure. Nevertheless, it's an interesting concept. Well, I don't know what I was thinking, exactly, when I rated PythonCard's ease of use...so I went back and changed it to rate it a lot higher. The ratings in this script were done a long time ago now and I need to re-do them, and add some new categories to rate also. Maybe this weekend... I have been thinking about doing a new version of this script that allows visitors to the web site to enter their own ratings for each GUI toolkit, for each criterion, store them by CGI and calculate a running average of the ratings, maybe eliminating the very extreme high and low scores to weed out spam, etc. Then, a visitor could use an online script with each GUI toolkit rated by the community for each criterion. I could do the same for Python IDE's, web frameworks, etc. Still, these would still be toys and not to be taken too seriously, but I might do it as a little project nonetheless. Concerning GUI toolkits, I find myself coming back to Tkinter these days. A lot of Python programs are written using Tkinter. I like to fool around with a lot of the old stuff on the web for free, miscellaneous apps and such, and there are still more Tkinter GUI's out there than anything else. Recently I have been having fun figuring out which new phone to buy. I decided to get a smart phone that could run Python. If I lived in Europe, or anywhere GSM rules, one of the Nokia series 60 would be a no -brainer. But here in the USA, I will probably will wind up getting a Windows based model. Guess what: Folks have Tkinter up and running on Pocket PC's and smartphones. I like that. Tkinter is everywhere. Don't forget, the Komodo IDE has a Tk based GUI builder. Just my 2 cents worth...

These measurements are not precise, but all of the below show Python catching or surpassing Perl today: 1. Number of newsgroup postings 2. Number of books published and sold 3. Number of universities offering courses 4. Number of commerical training courses and seminars offered 5. Number of job listings on internet job listing boards.

a new Python Podcast series (and the use of Python in creating podcasting tools)
Python411 is a series of podcasts about Python, aimed at hobbyists and others who are learning Python. Each episode focuses on one aspect of learning Python, or one kind of Python programming, and points to online tools and tutorials. Python related news and events will also be reported upon. This podcast series will probably not be of much interest to expert or professional programmers. I am a hobbyist and am not qualified nor capable of creating a podcast series for accomplished programmers. Maybe someone else will do that. The four podcasts so far are titled as such: Introduction to Python Computer Programming for Everybody GUI toolkits for Python Python for Mobile Devices New podcasts will appear from time to time. Interestingly, while on the subject of podcasts, I would like to point out that Python is emerging as the programming language of choice for creating tools for creating podcasts and using podcasts. For instance, iPodder is the leading podcast aggregator, or podcatcher, and is written in Python. Also, a new program called Podcatcher on a Stick is an open source Python project that is creating a podcatcher that runs on a mobile mp3 player itself, rather than on a PC. Links to these programs can be found on my web site.

Re: Python Cookbook
I want to just second this comment by Heike. I received my copy of the 2nd Edition from O'Reilly on Friday. I am still working my way slowly through the first chapter on Text, and I am nearing the end of that chapter. I intend to work my way through sequentially, because I can't think of a better way to improve my understanding of intelligent usage of Python. So far, even the recipes and discussions that are reach-out and difficult for me are beginning to make sense after I read carefully and sometimes re-read the discussions. I couldn't ask for better instruction, and the effort I make to learn is richly rewarded. I know that the material will become considerably more complex as I move deeper into the book, but the work of the authors and editors in chapter one gives me faith that I can make progress as I go, as long as I make the effort to really try to understand each recipe's discussion. This will no doubt be a valued reference work, but I am finding it to be a uniquely rewarding educational experience.

pyGoogle is fun and easy to use, and thinks Python is the best programming language
I am having a lot of fun using the pyGoogle module ( http://pygoogle.sourceforge.net/ ) that uses the Google API. It is about as easy to use as I can imagine, and it is a lot nicer than using my old HTMl screen scraping habits. My online CGI program Ask Merlin at www.awaretek.com/askmerlin.html is an example. Currently, the program takes any user's question and picks the best answer from amongst the possible answers given by the user. The program uses an algorithm that uses an intelligent analysis of search results from Google. OK, OK, I know already, that this is of limited utility compared to answering any question without requiring the user to give options to choose from; and, furthermore i know full well that at this point Merlin is far from foolproof even when given options to choose amongst. Still, if you play with it for a while you will be amazed at how well it does do. Moreover, I am hard at work on a version that will answer any question without being given options, by choosing options from Google search results that are most appropriate and then applying my intelligent algorithm. But hey, even as it stands, when queried which is the best programming language to use for ease of use, Merlin picks Python from amongst a list of python, ruby, ADA and java. When queried which language is the best programming language to use for a large project requiring realtime operation and involving life and death issues of human life, Merlin picks ada out of the same list. And, when just plain asked what is the best programming language Merlin wisely picks Python from the list. And I assure you that none of this is hard coded but instead just uses the regular algorithm applied to any other question ;- OK, it's just a fun little hack by a very amateurish hacker; but that's sort of the point. Just think what a good programmer could do with pyGoogle ;- -- http://mail.python.org/mailman/listinfo/python-list
