def chunks(total, step): assert total >= step while total > step: yield step; total -= step; if total: yield total
chunks(12, 4) [4, 4, 4] chunks(13, 4) [4, 4, 4, 1]
I'm not sure how appropriate "chunks" is as a name for such a function. Anyway, I wrote that because in a unit test I had to create a file of a precise size, like this: FILESIZE = (10 * 1024 * 1024) + 423 # 10MB and 423 bytes with open(TESTFN, 'wb') as f: for csize in chunks(FILESIZE, 262144): f.write(b'x' * csize) Now I wonder, would it make sense to have something like this into itertools module? --- Giampaolo https://code.google.com/p/pyftpdlib/ https://code.google.com/p/psutil/ https://code.google.com/p/pysendfile/
