referring to 'Python-coded class' and 'code' is referring to
'(compiled) Python code', and not machine code. Now, everything that
pickle pickles is a 'class instance' and class code can be compiled from
either Python or the interpreter's system language (

'U', 'ü', 'Ü', 'ú', 'Ú', 'û', 'Û', 'ù', 'Ù', 'v', 'V', 'w', 'W', 'x', 'X', 'y',
'Y', 'z', 'Z')
One way is to create a list of 2-lists / 2-tuples, like
[(modified_word_1, word_1), (modified_word_2, word_2), ...]
and to use the native sorting wich will use the first element
modified_word_2 as primary key.
The task lies in the creation of the primary keys.
I did it once for French (seriously) and for German (less
seriously) scripts. (Only as an exercise for fun).

Why does stringbench misspell the name Carmen Sandiego? Copyright avoidance?
Or ignorance. Perhaps I w
once instead of char by char, and with
the extra features mentioned above. I presume the purported advantage
over an after-the-fact transcript is focusing watcher attention on each
entry and response.

ad, 'lst' is written to.
What about:
self.lst.append(self.lst[-1]+self.lst[-2])
(which might collect Fibonacci numbers)?
'self' read, 'lst' read and written. Knowing that for non-builtins is
another matter ;-).

When I run this on the command line I see:
This is my program
Program is ending...
OK.. that's all folks!
When I run this in IDLE I see:
This is my program
Program is ending...
But the atexit handler is never called. ;-(
I tried in 3.3 idle and get the same.

ould I use to print "the-class-I-am-in good"
instead of hard-coding "Abc good"? I tried __class_ and self.__class__
self.__class__.__name__ or type(self).__name__)

The only thing special that IDLE does now is to color the text red. I
should sometime see how that is done. (Being able to doubleclick on an
item and have IDLE open an edit window at the specified line would be
really nice!)

for c in d: print(c)
So maybe I want {Abc:'http://example.com'} and o = s() instead.
Yes, as I suggested.

I agree with the complaint and you may have the germ of a good

performance so that we can all get the most out of Python. Any and all

The 'documentation' of how we build Python on Windows is the PCBuild

unt add 2 instead of 1, as f seems to? I don't
know, but perhaps because it is written in C rather than Python and
Python code objects are different from C code.)

Thank you.
Quite aside from the fact that there already was a quick reply telling
me the same thing. A properly threaded reader would have placed it just
below my post.
