I have a situation where I'm going to save some data sets to plot, but I don't know a-priori how many sets there will be. I'm using this code:

try: shape = list(phase_plots.shape) shape[0] += 1 phase_plots.resize (shape, refcheck=0) except NameError: phase_plots = empty ((1, 2*iterations+1, l))

This works, I'm just wondering if this is a reasonable approach or if maybe something else would be better (or more efficient).

I'd just append the data to a list. Arrays aren't meant to be dynamic and what you end up with is a bunch of reallocations and copies.
