Possible Duplicate:
Good Primer for Python Slice Notation

I’ve been reading over some sample code lately and I’ve read quite a few websites but I just can’t seem to get the query right to give me an answer I’m looking for. If anyone could help me out I’d appreciate it.

    It slices

    x[startAt:endBefore:skip]

    if you use skip = 2, every other element the list beginning at startAt and ending at endBefore will be selected. [Remember: indices live BETWEEN list elements]

    To see this, enter 

    x = range(100)

    at the Python prompt. Then try these things

    x[::2]
x[::3]
x[10:40:6]

    and see what happens.
