同じ値を持つ複数のサブディクテーションを持つPythonディクテーションを定義するにはどうすればよいですか？

Question

私はそのメンバー自身dictのあるPythonのdictを作成しようとしています、そのうちの2つが同じです：

servers = { 
    "test": { 
    "auth_token": "some-auth-token", 
    "client_id": "some-client-id", 
    "client_secret": "some-client-secret", 
    "scope": "some-scope" 
    }, 
    "live": { 
    "auth_token": "auth-token-for-live", 
    "client_id": "client-id-for-live", 
    "client_secret": "client-secret-for-live", 
    "scope": "scope-for-live" 
    }, 
    "demo": servers["test"] # this doesn't work, but this is what I need 
} 

マイdemoサーバー定義は、私のtestサーバー定義と同じであるが、私はしないでください私はこれをやることができる方法はありますか？

Answer 1

x = { 
    "auth_token": "some-auth-token", 
    "client_id": "some-client-id", 
    "client_secret": "some-client-secret", 
    "scope": "some-scope" 
} 

servers = { 
    "test": x, 

    "live": { 
    "auth_token": "auth-token-for-live", 
    "client_id": "client-id-for-live", 
    "client_secret": "client-secret-for-live", 
    "scope": "scope-for-live" 
    }, 

    "demo": x

Answer 2

servers = { 
    "test": { 
    "auth_token": "some-auth-token", 
    "client_id": "some-client-id", 
    "client_secret": "some-client-secret", 
    "scope": "some-scope" 
    }, 
    "live": { 
    "auth_token": "auth-token-for-live", 
    "client_id": "client-id-for-live", 
    "client_secret": "client-secret-for-live", 
    "scope": "scope-for-live" 
    }} 

servers['demo'] = servers['test']
