如何向现有词典添加密钥？

Question

我正在使用python3，并试图找出最简单的方法，将另一层添加到我的字典中。我有一本这样的字典

{ "block1": ["brian"], "block2": ["angel"], "block3": ["sally"] }

如何将名称添加到现有词典中

{ "name": { "block1": [ "brian" ], "block2": [ "angel" ], "block3": [ "sally" ] } }

Answer 1

d1 = { "block1": ["brian"], "block2": ["angel"], "block3": ["sally"] }

d1 = {"name":d1}

print (d1)
