我知道使用
1 | [' '.join(a[i:i+3]) for i in range(0, len(a), 3)] |
重新使用！
1 2 3 4 5 6 7 8 9 10 11 | from itertools import islice def split_every(n, iterable): i = iter(iterable) piece = list(islice(i, n)) while piece: yield piece piece = list(islice(i, n)) a = ['1', '2', '3', '4', '5', '6', '7', '8', '9'] new_a = [' '.join(slice) for slice in split_every(3, a)] |
主要是用这个。
