TypeError：列表索引必須是整數，而不是字典

我的json文件看起來喜歡這個，我試圖訪問for循環中的元素syslog。TypeError：列表索引必須是整數，而不是字典

     "reportfilename":"/var/home/FBML7HR/test/out.log", 
     "backuplogfile":"Clientlogs.txt" 
    } 
    } 
}

我不喜歡這樣寫道：

for i in data['execution']: 
    cmd = data['execution'][i]['test_case']['scriptname']

但我得到的錯誤說「類型錯誤：列表索引必須是整數，而不是字典」。我是python（和json）的新手。有人可以提出我要去哪裏嗎？

顯然'i'是'dict'，所以你不能用它來索引'data''execution']'。這不應該只是'我在數據['執行']：cmd = i ['test_case'] ['scriptname']'？ – jonrsharpe 2014-10-08 21:06:47

看起來像'data'是一個列表，而不是一本字典。你確定這本詞典沒有封閉的[]嗎？ – karthikr 2014-10-08 21:07:51

您遍歷的值由data['execution']引用的名單，不指數。

只要使用這些值（字典）直接：

for i in data['execution']: 
    cmd = i['test_case']['scriptname']

你可能想給一個更有意義的循環名稱：

for entry in data['execution']: 
    cmd = entry['test_case']['scriptname']

很好的解釋，謝謝！ :) – ocean800 2016-02-23 00:49:01
