LISTS: Extract every other element

[Skip Montanaro]

    Randall> I want to take a large list:
    Randall>   [ 1,2,3,4,5,6,7,... ]

    Randall> and build a list with every other element:
    Randall>   [ 1,3,5,7,... ]

    Randall> Is there a faster way than looping over indices?:

I'm pretty sure you can do this with NumPy.  I'm not a NumPy user though, so
I'll have to defer to the rocket scientists... ;-)
