python - 以良好可读的方式打印嵌套字典

Question

我希望以干净可读的格式打印嵌套字典。我已经完成了打印字典键及其值的标准方法，但由于这是嵌套的，所以它的呈现效果不是很好。有人可以解释一下我如何实现以下格式吗？

Host             Port    Service
192.168.1.200     80     IIS 7.5
                  443    IIS 7.5

192.168.1.201     22     SSHv.199

字典示例

192.168.1.200 {'3389': 'Microsoft Terminal Service', '49160': 'Microsoft Windows RPC', '49163': 'Microsoft Windows RPC', '135': 'Microsoft Windows RPC', '49152': 'Microsoft Windows RPC', '49153': 'Microsoft Windows RPC'}

Answer 1

您可以使用 json.dumps 的格式化选项:

>>> d={'server1':{'3389': 'Microsoft Terminal Service', '49160': 'Microsoft Windows RPC', '49163': 'Microsoft Windows RPC', '135': 'Microsoft Windows RPC', '49152': 'Microsoft Windows RPC', '49153':'Microsoft Windows RPC'},'server2':{'morekeys':'morevalues'}}
>>> print json.dumps(d, indent=4)
{
    "server1": {
        "3389": "Microsoft Terminal Service", 
        "49160": "Microsoft Windows RPC", 
        "49163": "Microsoft Windows RPC", 
        "135": "Microsoft Windows RPC", 
        "49152": "Microsoft Windows RPC", 
        "49153": "Microsoft Windows RPC"
    }, 
    "server2": {
        "morekeys": "morevalues"
    }
}
