Re: [Numpy-discussion] Relative speed

And as you pointed out, most of the time for non-trivial datasets the numpy operations will be faster. (I'm daunted by the notion of trying to do linear algebra on lists of tuples, assuming that's the relevant set of operations given the comparison to the matrix class.)

Note the important and pretty common exception of building up a list one element (or row of elements) at a time. Here, python lists usually rule, unless the final size is known in advance.
