python - 在 Python 中将一个数字字符串的键拆分为单个数字键

Question

我想翻下面的字典:

dictionary = {
    4388464: ['getting']
    827862 : ['Taruma', 'Varuna']
    ...
}

进入:

dictionary = {
    4: {3: {8: {8: {4: {6: {4: {'words': ['getting']}}}}}}}
    8: {2: {7: {8: {6: {2: {'words': ['Taruma', 'Varuna']}}}}}}
    ...
}

这样我就可以像这样使用字典:dictionary[8][2][7][8][6][2]['words'] 而不是:字典[827862]。

Answer 1

import pprint

dictionary = {
    4388464: ['getting'],
    43881: ['got'],
    827862 : ['Taruma', 'Varuna'],
}

d2 = {}

def add_it(d, k, words):
    knum = int(k[0])
    if len(k) == 1:
        d[knum] = {'words': words}
    else:
        dsub = d.setdefault(knum, {})
        add_it(dsub, k[1:], words)

for k, words in dictionary.items():
    add_it(d2, list(str(k)), words)


pprint.pprint(d2)

打印:

{4: {3: {8: {8: {1: {'words': ['got']},
                 4: {6: {4: {'words': ['getting']}}}}}}},
 8: {2: {7: {8: {6: {2: {'words': ['Taruma', 'Varuna']}}}}}}}
