Add itertools.batched() #98363
Description
This was requested on python-ideas:
def batched(iterable, n):
"Batch data into lists of length n. The last batch may be shorter."
# batched('ABCDEFG', 3) --> ABC DEF G
if n < 1:
raise ValueError('n must be >= 1')
it = iter(iterable)
while (batch := list(islice(it, n))):
yield batch
