Comment (by JoalHeagney):
I also got the second lambda function incorrect. We're testing if any
values are outside the range 4 (inclusive) to 10 exclusive in my example
matrix.
so it should be something like:
{{{
lambda x: (x < 4 | x >= 10)
}}}
or even better
{{{
lambda x: x not in range(4,10)
}}}
I did get an iterator-only method for getting elements of a matrix using
this:
{{{
(A[valrow][valcolm] for valrow in xrange(A.dimensions()[0]) for valcolm in
xrange(A.dimensions()[1]))
}}}
But then I realized that since we're only using this function
(theoretically) in doc-checking, we probably don't have to worry about
memory concerns and iterators versus lists. jhpalmieri's approach seems
nice and simple.
