從JSON文件中提取值Python錯誤

我試圖從JSON文件中提取某些值。這是我的代碼。從JSON文件中提取值Python錯誤

ifile = open(ifile_name, 'r') 

json_decode=json.load(ifile) 
result = [] 
for item in json_decode: 
    my_dict={} 
    my_dict['Culture']['Movies']['2014']['Gravity']= item.get('Director') 
    my_dict['Culture']['Movies']['2014']['Blue Jasmine'] = item.get('Director') 
    print my_dict 
    result.append(my_dict) 
    back_jason=json.dumps(result, ofile) 
    with open(ofile_name, "w+") as file : 
     file.write(back_jason)

我試圖提取導演誰在2014年執導的影片不過的名字，當我運行上面的代碼，我給下面的錯誤。

my_dict['Culture']['Movies']['2014']['Gravity']= item.get('Director') 
AttributeError: 'unicode' object has no attribute 'get'

任何人都可以解釋爲什麼我從我的代碼中得到這個錯誤？

這裏是JSON文件

帖子什麼是文件即樣本文件內容 – SIslam

@SIslam我有內容更新的問題的JSON文件，抱歉。 – colin

你能澄清一下你想寫在第二個文件（ofile_name）中嗎？ - 只是導演的名字？您正試圖以不好的方式構建字典（my_dict）。 – SIslam

儘量只迭代器作爲關鍵dictionary-

import json 

ifile = open(r"D:\tst.txt", 'r') 

json_decode=json.load(ifile) 
result = [] 
for i in json_decode['Culture']['Movies']['2014']: 
    data = json_decode['Culture']['Movies']['2014'][i]['Director'] 
    print data 
    result.append(data) 

with open(r"D:\tst1.txt", "w+") as file : 
    for j in result: 
     file.write(j+'\n')

輸出文件的內容 -

Frank Coraci 
Emilio Lazaro 
Woody Allen 
Alfonso Cuaron
