  • @aganders3 - note that the OP didn't know what the operator did, so the bit shift wiki would not have been helpful -- other than as a side door answer to the question :) Commented Feb 8, 2012 at 22:17

n >> 1 shifts n right 1 bit. This is the same as dividing by 2.

More generally, n >> m shifts n right m bits, giving a division by 2^m.

Just for completeness, note that there's a completely different usage which is changing the stream that print uses by default:

print >> sys.stderr, message

For more information, please have a look at this related question.

It's the bitshift operator:
