Question

我有两个python dicts：

payload = {"key1":{"a":"1"},"key2":{"b":"2","c":"3"}}

和

data = {"1":"John","2":"Jacob"}

我希望我的输出为：

{"key1":{"a":"John"},"key2":{"b":"Jacob","c":""}}

我尝试正确打印值的任何方法，但不更新输出字典。

Answer 1

我知道没有单一的方法，但您可以使用：

for k, v in payload.viewitems():
   payload[k] = {}
   for kv, vv in v.viewitems():
      payload[k][kv] = data.get(vv, "")

如果您再检查payload它有你所追求的内容：

{'key2': {'c': '', 'b': 'Jacob'}, 'key1': {'a': 'John'}}

Answer 2

您可以使用dict comprehension执行此类操作：

payload = {"key1":{"a":"1"},"key2":{"b":"2","c":"3"}}
data = {"1":"John","2":"Jacob"}

final = {k: {i:data[j] if j in data.keys() else "" for i, j in payload[k].items()} for k in payload}
print(final)

输出：

{'key2': {'b': 'Jacob', 'c': ''}, 'key1': {'a': 'John'}}

根据两个python dicts创建一个dict
