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?
