difference between iterblocks and nchunks

[simonm3]

From the code below there are 62 blocks but nchunks is 61. Why is that?

import bcolz
a=bcolz.carray(np.array([1,2,3,4]*999999))
print(len(list(bcolz.iterblocks(a))), a.nchunks)

Yes, that's intended. a.nchunks is the number of chunks that are complete, whereas iterblocks iterates over the remainder block.

Thanks. Would be useful to add something to the docs on the difference between blocks and chunks. I searched for it but didn't find anything.
