Re: Picking a license

utf-8 and ctypes

n the ascii subset of UTF-8 are discarded by c_char_p during the conversion, or at least they don't print out when I go to print the string. Does python not support utf-8 strings? Is there some other way I should be doing the conversion? Thanks, Brendan -- http://mail.python.org/mailman/listi

Python benefits over Cobra

Python3 "designed right" (was: PYTHONPATH)

(or Mono), though the web pages do suggest they are also working on a version that runs on JVM.

Help using Thread (or other method)

Re: WxPython versus Tkinter.

Since it seems the python motto is "Batteries included", then it would seem to me that wxPython is the natural fit as it also has "Batteries included" (e.g. accessibility, native look-n-feel, mature and evolving, can produce simple or complex gui programs, etc, etc)

Re: wxPython in the context of Eclipse

already done). If I recall correctly, I had to specify the python interpreter to use. It added a whole lot of paths to the PYTHONPATH variable which caused me some grief. I ended up removing them all (or most of them) and it worked fine after that. Cheers, Brendan. -- Brendan Simon
