从其他词典创建嵌套词典

Question

我可以通过从值列表中创建一个字典来创建一个复杂的字典，并将值添加到列表中：

NEED=  {'need1': ['good1', 'good2'], 'need2': ['good2', 'good3']}
DM= {'good1': 1, 'good2': 1, 'good3': 10}

NG = {
    n_key: [
        {n_ch_key: DM[n_ch_key] for n_ch_key in n_l}
    ] 
    for n_key, n_l in NEED.items()
} 
OUT:{'need2': [{'good2': 1, 'good3': 10}], 'need1': [{'good2': 1, 'good1': 1}]}

但是如何创建这样的字典：

IN: CN= {'need1': 3, 'need2': 2}
    NEED= {'need1': ['good1', 'good2'],'need2': ['good2', 'good3'] }

OUT: NG={'need1': [{'good1': 3, 'good2': 3}], 'need2': [{'good2': 2, 'good3': 2}]}

Answer 1

没有什么比你刚写的更复杂：

NG = {
    n_key: [
        {n_ch_key: CN[n_key] for n_ch_key in n_l}
    ] 
    for n_key, n_l in NEED.items()
}
