def list_grouping(data:list, child_length:int) -> list:
'''列表分组[1,2] -> [[1],[2]]'''
groups = zip(*(iter(data),) * child_length)
target = [list(i) for i in groups]
count = len(data) % child_length
target.append(data[-count:]) if count !=0 else target
return target
执行
list_grouping([1,2,3,4,5],2)
结果
[[1, 2], [3, 4], [5]]
