Question

我有两个字典如下。

d1 = {
       "user1":{"key1":"val1","key2":"val2"},
       "user2":{"key3":"val3","key4":"val4"}
     }

d2 = { "admin":{
      "user1":{"key5":"val5","key6":"val6"},
      "user3":{"key7":"val7","key8":"val8"}
                }
     }

最终字典应如下所示：

d3 = {
              "user1":{"key1":"val1","key2":"val2","key5":"val5","key6":"val6"},
              "user2":{"key3":"val3","key4":"val4"},
               "user3":{"key7":"val7","key8":"val8"}
              }

合并概念并不适用于此。你能帮帮我吗？

我已尝试过How to merge two Python dictionaries in a single expression?的解决方案。以下解决方案与我需要的不同。

{'admin': {'user3': {'key8': 'val8', 'key7': 'val7'}, 'user1': {'key6': 'val6',
'key5': 'val5'}}, 'user2': {'key3': 'val3', 'key4': 'val4'}, 'user1': {'key2': '
val2', 'key1': 'val1'}}

Answer 1

您可以获取第一个字典的副本，然后迭代另一个 - 创建一个默认的空字典，然后使用d2的内容更新它，例如：

d3 = d1.copy()
for k, v in d2['admin'].iteritems():
    d3.setdefault(k, {}).update(v)

为您输出：

{'user1': {'key1': 'val1', 'key2': 'val2', 'key5': 'val5', 'key6': 'val6'},
 'user2': {'key3': 'val3', 'key4': 'val4'},
 'user3': {'key7': 'val7', 'key8': 'val8'}}

如何俱乐部词典？
