An SQLite database is a single file. But it can't be "in the same file" as the .py file (I don't think). What's your goal? If you just want to distribute a single file to your users, you can make an executable Python file and have it create a fresh (empty) SQLite database once it runs for the first time. -- http://mail.python.org/mailman/listinfo/python-list

It's cross platform, but it does require occasional platform-dependent tweaks, since it mostly uses native controls and sometimes the native controls' requirements are different. You might want to consider that it's going to be some time before the 3rd party libraries catch up to Python 3.

Boa (Boa Constructor) is really nice for wxPython GUI work, but it has some bugs when using Linux that might be dealbreakers for the user. At least I have had problems on Ubuntu 8.10 64 bit (but none or very few with WinXP). For those that might care, they are (as of now, Boa 0.6.1-4) are: - The File -> New option is cut off in the menu. But that can be gotten around by using the Palette to choose the same options. - No gridlines in the Frame Designer (makes it harder to use) - Some problems with the height of the rows in the Inspector, at least with 64 bit Ubuntu, some of which can be fixed with this workaround: https://bugs.launchpad.net/ubuntu/+source/boa-constructor/+bug/313952 and there is a note there saying it has been patched in a 0.6.1-6 version in a Debian repository.

Likely this is not the best way, but I would do, for
the first one (and the same idea for the second):
def convert(date):
frenchdict = {'Mai':'May'} #etc...
day = mystring[:2]
month = frenchdict[ mystring[3:6] ]
year = mystring[7:11]
newdate = year+'-'+month+'-'+day

As a hobbyist--and not a real programmer*--I think I chose Python (I don't really recall now) because of things like: - There is a good community, including tutor list, etc. - I wanted something that would run cross-platform (so no Visual Basic). - Preferred something free (so no REALBasic). - I wanted a high level language. - It seemed easiest to read and learn. I like mandatory indents, for example. - There are a lot of libraries for it with good support. - I liked the Zen of Python philosophy (to the extent I understood it). - Some high profile entities were using it, so it must have something going for it. - It was new enough to be a possible improvement over older languages while old enough to be established. - Who can't like a computer language named Python? Drawbacks: - AFAIK, running multiple Python apps all show up in the Windows task manager as "python.exe" (common to all non-compiled languages?) instead of the app's name. - Distributing as an executable is not as straightforward as I might hope. - I wish Python 3 wouldn't break my 2.5 code. - If it could be quicker (compiled), that would be better.

It has a built-in toolbar that allows for changing the plot (zoom, pan, etc), and has good support for point picking (clicking on a datapoint to do send an event).

I picked it up enough to do what I want to do and have been quite happy with it. I learned (my small subset of) it here and there over a year or so I guess, just as I felt like it, as it was purely for hobby (and I still learn new stuff of course). If you are hellbent on learning it and have good instructional material, you could learn a lot in a good month, really. My best advice is to get a couple of ultra-basic short tutorials read/viewed, and then identify *what it is you want to use Python to do*. Any language can be used to essentially anything, and I feel it is better to learn *per task* than to try to simply learn the whole language. You will feel better having accomplished something in line with your goals. In terms of good tutorials for absolute beginners, here are two: Alan Gauld's Learning to Program http://www.freenetpages.co.uk/hp/alan.gauld/ ShowMeDo.com has lots of Python instructional videos, including this one for absolute beginners: http://showmedo.com/videotutorials/series?name=irgGc9ChS I also recommend the Python tutor list, which you can sign up for here: http://mail.python.org/mailman/listinfo/tutor So what is it that you want to use Python for?
