字典的嵌套字典

Question

我正在尝试嵌套两个字典，也许只制作一个字典更容易，但是，我有相同的键但具有不同的值，只更改键会更容易还是有办法嵌套这两个？

Number_As = 1

#DNA dictionary
DNAdict = {
  'A': ['dAMP',1,..., other values],
  'C': ['dCMP',2,..., other values],
  'T': ['dTMP',3,..., other values],
  'G': ['dGMP',4,..., other values]}

#RNA dictionary
RNAdict = {
  'A': ['AMP',5,..., other values],
  'C': ['CMP',6,..., other values],
  'U': ['UMP',7,..., other values],
  'G': ['GMP',8,..., other values]}

然后我尝试访问各个值以进行不同的计算：

Energy of DNA_A = Number_As * DNAdict['A'][1]

Energy of DNA_A = 1

or 

Energy of RNA_A = Number_As * RNAdict['A'][1]

Energy of RNA_A = 5

但我希望只有一本字典，然后尽管名称相同，但可以访问每个键的不同值。可能吗？

非常感谢！！

Answer 1

你怎么知道你现在想使用哪个字典？如果您想对处于当前状态的字典的各个元素保持很少的控制（例如，['dAMP',1,..., other values]，您可以将字典的值设为列表的列表，并通过索引引用所需的元素。但是，如果你可以为每个元素分配一个唯一的名字，你确实可以用下面的代码创建一个嵌套的字典：

# Your current code goes here

acids = {'DNA': RNAdict, 'DNA': DNAdict}

# Then you can access a specific dict by
dna_a_energy = Number_As * acids['DNA']['A'][1]
rna_a_energy = Number_As * acids['RNA']['A'][1]

如果我理解正确的话。

Answer 2

是的，所有的可能性，都有可能

1：硬编码：

grouped = {
'DNAdict':{
  'A': ['dAMP',1,..., ],
  'C': ['dCMP',2,..., ],
  'T': ['dTMP',3,..., ],
  'G': ['dGMP',4,..., ]},
'RNAdict':{
  'A': ['AMP',5,..., ],
  'C': ['CMP',6,..., ],
  'U': ['UMP',7,..., ],
  'G': ['GMP',8,..., ]}
}

#acessing RNAdict a[0]

value = grouped['RNAdict']['A'][0]
print(value)

2：按代码分组

#RNA dictionary
DNAdict = {
  'A': ['dAMP',1,..., ],
  'C': ['dCMP',2,..., ],
  'T': ['dTMP',3,..., ],
  'G': ['dGMP',4,..., ]}

#RNA dictionary
RNAdict = {
  'A': ['AMP',5,..., ],
  'C': ['CMP',6,..., ],
  'U': ['UMP',7,..., ],
  'G': ['GMP',8,..., ]}

grouped = {'DNAdict':DNAdict,'RNAdict':RNAdict}

#example of finding
value = grouped['RNAdict']['A'][0]
print(value)

3 添加前缀：


def add_prefix(elem:dict,prefix:str)->dict:
    new_dict = {}
    for key in elem.keys():
        new_dict[f'{prefix}_{key}'] = elem[key]
    return new_dict


DNAdict = {
  'A': ['dAMP',1,..., ],
  'C': ['dCMP',2,..., ],
  'T': ['dTMP',3,..., ],
  'G': ['dGMP',4,..., ]}

#RNA dictionary
RNAdict = {
  'A': ['AMP',5,..., ],
  'C': ['CMP',6,..., ],
  'U': ['UMP',7,..., ],
  'G': ['GMP',8,..., ]}

Dna = add_prefix(elem=DNAdict,prefix='DNA')
Rna = add_prefix(elem=RNAdict,prefix='RNA')
Nested= {**Dna, **Rna}
