在字典中将字符串键转换为int [英] Convert a string key to int in a Dictionary

问题描述

我的问题非常类似于这个，除了我有一个列表的字典，我有兴趣在每个列表形式中更改键值和所有元素 string 到 int 。

My question is very similar to this one, except I have a dictionary of lists and I'm interested in changing both the key value and all elements in every list form string to int.

所以例如我想要的字典：

So for instance I'd like the dictionary:

{ '1':['1', '2', '3', '4'] , '2':['1', '4'] , '3':['43','176'] }

成为： / p>

to become:

{ 1:[1, 2, 3, 4] , 2:[1, 4] , 3:[43,176] }

这是可能吗？

因为我从一个 JSON 格式文件创建此字典

More in general since I created this dictionary from a JSON format file

{0 ：[1，2，3，4]，1：[0，2，3，4，27，94，$ b $ $ b94 ，3：[0，1，2，4，377]，4：[​​0，1，2 5：[6，7，8]，6：[5，7，8 ]，7：
[5，6，8，14，23，40，74，75，76 ，371，
372]，8：[5，6，7，66]，9：[10，11 12]，10：
[9，11，12，56，130，131]}

{"0": ["1", "2", "3", "4"], "1": ["0", "2", "3", "4", "27", "94", "95", "97", "128", "217", "218", "317"], "2": ["0", "1", "3", "4", "94", "95"], "3": ["0", "1", "2", "4", "377"], "4": ["0", "1", "2", "3", "27", "28"], "5": ["6", "7", "8"], "6": ["5", "7", "8"], "7": ["5", "6", "8", "14", "23", "40", "74", "75", "76", "362", "371", "372"], "8": ["5", "6", "7", "66"], "9": ["10", "11", "12"], "10": ["9", "11", "12", "56", "130", "131"]}

具有以下说明：

json_data = open("coauthorshipGraph.txt")
coautorshipDictionary = json.load( json_data )
json_data.close()

is there a way to do it directly at loading time?

推荐答案

d = {'1':'145' , '2':'254' , '3':'43'}
d = {int(k):int(v) for k,v in d.items()}
>>> d
{1: 145, 2: 254, 3: 43}

值

>>> d = { '1':['1', '2', '3', '4'] , '2':['1', '4'] , '3':['43','176'] }
>>> d = {int(k):[int(i) for i in v] for k,v in d.items()}

在您的情况下：

coautorshipDictionary = {int(k):int(v) for k,v in json.load(json_data)}

或

coautorshipDictionary = {
    int(k):[int(i) for i in v] for k,v in json.load(json_data)}
