Question

我有一个存储键值对的字典：

s={"one":["two","three","four"],"two":["five","six"],"three":["ten","nine"]}

我希望能够拥有一个带有键的字典＆＃34;一个＆＃34;和列表

["test","succesfull"]

所以最终结果将是：

s={"one":["two","three","four"],"two":["five","six"],"three":["ten","nine"],"one":["test","succesfull"]}

我需要能够拥有两个具有不同值的相同键，并且仍然可以独立访问其中任何一个

Answer 1

我的方法是再增加一个级别，

s={"one":{"data": ["two","three","four"], "test": "successfull"},"two":["five","six"],"three":["ten","nine"]}

希望满足要求

Answer 2

我认为最好的方法是将列表列表（列表字典，如果你想要键）作为字典值，在同一个键下存储多个条目，这里是列表列表：

# setup
class dd_list(dict):
    def __missing__(self,k):
        r = self[k] = []
        return r
d = dd_list()

d['one'].append(["two","three","four"])
d['two'].append(["five","six"])
d['three'].append(["ten","nine"])

#adding 'one' key again
d['one'].append(["test","successful"])

print (d)
#{'three': [['ten', 'nine']], 'two': [['five', 'six']], 
#'one': [['two', 'three', 'four'], ['test', 'successful']]}

Answer 3

python dict键的一个属性是唯一的...

所以在python词典中键应该是唯一的......但是你可以在运行时定义重复...一旦你的dict被存储，副本将被自动删除或者它将被更新。

在运行时，您可以像这样创建

mydict = {"a":1, "b":2, "c":3, "a":3}

但如果你打印它应该是，

mydict = {"a" :3, "b":2, "c":3}

这里将覆盖最近的值

相同的键具有不同的值字典
