從json文件中提取條件值

Question

我已經創建了以下代碼來解析JSON文件並提取滿足特定條件的某些值並將它們放入文本文件中。我的代碼運行沒有錯誤，對我來說看起來沒問題。但是，當我打開文本文件時，它是空白的。

def my_main(ifile_name, ofile_name): 

ifile = open(ifile_name, 'r') 
ofile = open(ofile_name, "w") 
json_decode=json.load(ifile) 
result = [] 
for i in json_decode['Culture']['Movies']: 
    for k in json_decode['Culture']['Movies'][i]: 
     if "Oscars" in json_decode['Culture']['Movies'][i][k] == 0 and "Genre" in json_decode['Culture']['Movies'][i][k] == Comedy: 
      data = "Actors" in json_decode['Culture']['Movies'][i][k] 
      print data 
      result.append(data) 

for j in result: 
    ofile.write(j+'\n') 

JSON文件是以下

{ 
    "Culture": { 
     "Movies": {

      } 
     } 
    } 
} 

我試圖讓誰在一部喜劇電影贏得0 OSCARS發揮演員的名字。從我的代碼看，它看起來很適合我，希望有人能解釋。

首先，你給的json文件最後缺少了一個括號。其次，這是工作代碼。你在if條件和數據初始化方面錯了。

import json 
def my_main(ifile_name, ofile_name): 
    ifile = open(ifile_name, 'r') 
    ofile = open(ofile_name, "w") 
    json_decode=json.load(ifile) 
    result = [] 
    for i in json_decode['Culture']['Movies']: 
     for k in json_decode['Culture']['Movies'][i]: 
      if json_decode['Culture']['Movies'][i][k]['Oscars'] == 0 and json_decode['Culture']['Movies'][i][k]['Genre'] == "Comedy": 
      data = json_decode['Culture']['Movies'][i][k]['Actors'] 
      print data 
      result.append(data) 

for j in result: 
    ofile.write(str(j)+str('\n')) 

my_main('movies.json','o.txt')
