Re: Python IDE
Hi,
With a python-enabled VIM it's possible to execute and thus test the
python code. I have the following lines in my vimrc.
F2 prints the result of a line evaluation on the bottom or in a window
named pyout if there. I open pyout with ":vert rightb new pyout" mapped to
F1.
F4 does the same on the selected part of a line
F3 evaluates without printing
py import vim

if vim.buffers[i].name and vim.buffers[i].name.find("pyout")!=-1:

return iPy

RE: c[:]()
Hi,
I have started to look into the last postings. It is funny and sad how
people talking the same language cannot understand each other.
I have become curious on what exactly you mean.
Warren, can you please restate your point.
When doing so, please define every identifier or non-plain english word
before you use it and be concise.
e.g.
You cannot use b if it is not clear what it means.
When writing "c[:]()" there is no "b". So where does "b" come from?
You told us that "b" is a container (*), but where should the python
interpreter or the people take it from.
People start to guess, as I did:
(1) - Might you mean: "b() for b in c". (I use python syntax here)
This means c is a container, an undertanding that is supported
also by the used slicing ("[:]").
(2) - Let's suppose that by (*) you mean that, in addition to "c", "b"
is a container, too.
(3) - Now for a standard container "b()" does not make sense. Maybe you
mean "b[:]()" according to the guessed interpretation (1).
This would then be a recursive evaluation of all functions with no
parameters in a tree ("tree" in the informatics sense).
(end of my guess)
I think somehow it should be possible to convey an idea so that others can
grasp it.
If it does not work the first time, it is good to clarify the points that
one found others to misunderstand.
Otherwise one risks to be regarded as esoteric.
Thanks, Roland

Re: how to mimik a main() function to start a program with entry point?
Hi, >From a python module you could use subprocess and start the exe. Normally one must leave it to the OS to load a binary module, because there are certain things done during loading. Nevertheless the location of the entry point is coded in the binary file format (e.g. PE for windows or ELF for Linux) Whether it is possible from python to make an import of a python module in a python package gone through py2exe, I cannot answer.
