pythonic从nest字典中调用特定键/值的方法(pythonic way of calling specific keys/values from a nest dictionary)

 什么是从嵌套字典中获取特定键/值的pythonic方法？ 
 
 例如，我想从这个嵌套字典中获取奇数的所有dict值： 
 
nested_dict = {'bulldog': {'type': 3}, 'cat': {'type': 4}, 'yorkie': {'type': 11}, 'pitbull': {'type': 8}}
 
 输出应该如下所示： 
 
new_dict = {'bulldog': {'type': 3}, 'yorkie': {'type': 11}}
 
 另外，如果我想只拉出具有奇数值的嵌套键，在这种情况下输出将如下所示： 
 
new_dict2 = {'type': 3, 'type': 11}

What's a pythonic way of getting specific keys/values from a nested dictionary? 
 
For instance, I want to get all the dict values that are odd from this nested dictionary: 
 
nested_dict = {'bulldog': {'type': 3}, 'cat': {'type': 4}, 'yorkie': {'type': 11}, 'pitbull': {'type': 8}}
 
The output should look something like this:
 
new_dict = {'bulldog': {'type': 3}, 'yorkie': {'type': 11}}
 
Additionally, what if I wanted pull only the nested keys with an odd value, in which case the output would look like this:
 
new_dict2 = {'type': 3, 'type': 11}
