Iterate over a python sequence in multiples of n?

Question

How do I process the elements of a sequence in batches, idiomatically?

For example, with the sequence \"abcdef\" and a batch size of 2, I would like to do something

Answer 1

I am sure someone is going to come up with some more "Pythonic" but how about:

for y in range(0, len(x), 2):
    print "%s%s" % (x[y], x[y+1])

Note that this would only work if you know that len(x) % 2 == 0;
