Question

n = [1，[2，[3，[4,5]]]，[6，[7，[8，[9]]，10]]]

在python中，我想在函数'print_list'中编写一个嵌套函数，该函数以递归方式为每个子列表调用自身。嵌套函数应该有一个额外的参数缩进，用于跟踪每个递归级别的缩进。在实现print_list（n）时，它以下列格式打印嵌套列表'n'

print_list（n）的



.1

..... 2

......... 3

............. 4

............. 5

..... 6

......... 7

............. 8

Answer 1

我有一种不好的感觉，我正在做你的作业..无论如何..确保你理解代码..

n = [1, [2, [3, [4, 5]]], [6, [7, [8, [9]], 10]]]

def reqprint(inputdata, depth=0):

    if isinstance(inputdata, list):
        for sublist in inputdata:
            reqprint(sublist, depth=depth+1)
    else:
        print('.' * depth + str(inputdata))

reqprint(n)

运行时

.1
..2
...3
....4
....5
..6
...7
....8
.....9
...10

Answer 2

import pprint

n = [1, [2, [3, [4, 5]]], [6, [7, [8, [9]], 10]], 11]


def printList(list_name, level = 0):
    for sub_element in list_name:
        if isinstance(sub_element, list):
            printList(sub_element, level+4)
        else:
            print '.' * level + str(sub_element)

printList(n)
pprint.pprint(n, width=4)
