What is this: d = [ int(x) for x in s.split(":") ]
That's called list comprehension. The notation
[f(x) for x in A if p(x)]
means:

Hello list,
I have been coding in python a short while and I have been wondering
which approach should I take on documentation (API docs) for a python
library I have been working on, there is currently code docstrings,
docstrings with some markup (epydoc, etc), or external programs such
as Sphinx

Nope. I just tried it. It works fine from there. Interesting, as far as
I know, the author wanted us to run it from IDLE. That may explain some
other oddities. I'll check with him. I'm quite sure in his user manual
he never talks about the command console.

An interesting thought, I'll ponder it. Note though the use of control
variables like IntVar, etc. In the 2000 line original version of all
the program, integers, dates, and booleans are in use for the
simplified widget I produced. Note to the use of self.anumberVar.set.

I browsed through your response, and it looks like this may be doable.
I'll look this over more carefully this evening. It seems as though
someone should have had a similar problem in the past. The Tkinter
interface seems to be a, I hope, temporary logjam. I don't recall

class IntVar_GUI:
I just noticed the name of the class. This kind of implies that you

intending writing GUIs for each data type? That shouldn't be necessary
since the inputs will be strings in each case. You only need to call
the appropriate conversion
destroy() took care of it, but I wonder what advantage there was to
Quit()?
destroy destroys the widget, quit exits the main loop.
destroying the top level widget usually causes the mainloop; to die
too
so the end result is the same (provided you have no non-modal dialogs
open?).

BTW, the Quit function is original but doesn't kill the window when
Quit is used.
Does that include running from the command console?
Is this another IDLE/Tkinter issue maybe?

Hello all, I'm using the Shelve module to store dictionaries in a list
as a value of a key.
So:
key = [{'keyA' : 1, 'keyB' : 2}, {'key1' : 1, 'key2' : 2}]
The problem is I can't remove a dictionary from the list.

s = shelve.open('file')

Hello, I am attempting to make a simple animation of a vibrating string using

I haven't been able to find much information on how to do it.
I have my data of position x on the string at time t. I can plot it with
