Damn. I should give up and go golfing. _Lists_ are variable-length and can be heterogenous. _Arrays_ are homogenous and sort-of fixed length. > [...] I was thinking more of NumPy arrays, where you can create an > arbitrary sized homogeneous array of a desired type (either > uninitialized or filled with zeros or ones): > > > http://www.scipy.org/Tentative_NumPy_Tutorial#head-d3f8e5fe9b903f3c3b2a5c0dfceb60d71602cf93 > > If you're crunching so many numbers that initializing a list is > a problem, then you probably ought to be using NumPy. -- Grant Edwards grant.b.edwards Yow!
