Sort array inside a dict based on datetime

I would like to sort my versions array based on the modified_datetime key. I can definitely use one of the sorting algorithms to do it but I'm just wondering if there is an efficient way to do it in Python.

my_json = {
  "versions": [
    {
      "migrated_versions": [ 
        {
          "modified_datetime": "2020-09-11T21:15:22.215Z"
        }
      ],
    },
    {
      "migrated_versions": [ 
        {
          "modified_datetime": "2020-09-11T21:14:19.162Z"
        }
      ]
    },
    {
      "migrated_versions": [ 
        {
          "modified_datetime": "2020-09-11T21:10:19.289Z"
        }
      ]
    }
  ]
}

Since the datetimes are ISO8601, which is lexicographically sortable, you can just use the sorted() built-in (or list.sort()) with the key= argument:

sorted(my_json["versions"], key=lambda v: v["migrated_versions"][0]["modified_datetime"])
