Python: "There's Only One Way To Do It"
import array import numarray import numeric import numpy
They're all almost the same, but not quite.
When google gives you an online piece of documentation, it's hard to say what it refers to.
And different scientific modules use one or the other, more or less unpredictably.
Maybe in the future numpy will replace them all.
In the meantime, if I hear someone saying "There's Only One Way To Do It", I will spank their cheeks with a wet fish.
