What you claim about introspection code though I think holds for code

If you insist on using exec (which, again, you have no reason to for

s that the vertices iterator creates new vertex objects every
time instead of iterating over the existing ones. This essentially
prevents, among other things, storing vertices as keys in a dictionary
since the hashes of the stored and the new vertex differ although they
compare equal. Is this real
h the
complexity and the error-proneness of having two new
similar-but-not-quite-the-same APIs with sets. Not only iteration is
arguably the most common operation on a view, but the cost (in extra
keystrokes and runtime performance) of populating any container that
the user may need from an iterator is pretty low.

Optimization flags should never change the behavior of a program, so
using assertions for what's part of the normal program behavior
(validating user-provided input) is wrong.

"enjoy" tests.

It is
ust works. Same scripts run on every platform. Bindings
available to every C/C++/FORTRAN library I've needed so far. Often
the bindings are not complete, but oddly enough the binding developers
have chosen to do just the functions I need, so who cares. A clean
architecture for adding more f
ey do not have the authority to actually define its
legal ramifications. Check with your company legal staff.
Having said that, I have been troubled by trolltech's approach from
the beginning, and therefore stay away from it. PyGTK and wdxPython
are solid GUIs, without the legal uncertainty.

open('my_space_separated_file.txt')]
This stores the values as a list of lists, each list corresponding to a
row in the file. Depending on what you plan to do next with these
numbers, this may or may not be the best way to go about it, but since
you only mentioned the file reading part, we can't assume much.
