json.dumps()函數(shù)是將一個Python數(shù)據(jù)類型列表進行json格式的編碼
json.loads()函數(shù)是將json格式數(shù)據(jù)轉換為字典

import json
data = [{
  "results": [
    {
      "latitude": 45.758718,
      "elevation": 953,
      "longitude": -108.502049
    }
  ]
}] 
in_json = json.dumps(data) # Encode the data
for i in json.loads(in_json):
    print(i['results'][0]['latitude'])
