How to parse json using cycle

Could someone help me please how I can parse such kind of json in Python? I’m assuming that here should be a cycle, but I’m not sure how to implement it.

{
  "Info": {
    "a": 1,
    "b": [
      {
        "a1": 555,
        "a2": 555,
        "a3": {
          "b1": 555,
          "b2": {
            "c1": 555
          }
        }
      },
    {
        "a1": 555,
        "a2": 555,
        "a3": {
          "b1": 555,
          "b2": {
            "c1": 555
          }
        }
      },
      {
        "a1": 555,
        "a2": 555,
        "a3": {
          "b1": 555,
          "b2": {
            "c1": 555
          }
        }
      }
    ]
  }
}

Use the json module.
