generate JSON file content

问题

以下是Python代码示例，可生成包含与file-1相同内容的另一个JSON文件，其中每次用户名和优先级不同：

  1. import json
  3. # 从file-1中读取JSON数据
  4. with open('file-1.json', 'r') as infile:
  5.     json_data = json.load(infile)
  7. # 创建一个新JSON对象，用于存储重复的数据
  8. new_json_object = {"Aps": []}
  10. # 重复100次
  11. for i in range(1, 101):
  12.     # 复制原始数据
  13.     new_entry = json_data["Aps"][0].copy()
  14.     
  15.     # 更新用户名和优先级
  16.     new_entry["attributes"]["name"] = f"user{i}"
  17.     new_entry["attributes"]["priority"] = str(100 - i * 10)
  18.     
  19.     # 添加到新JSON对象中
  20.     new_json_object["Aps"].append(new_entry)
  22. # 写入新JSON数据到文件
  23. with open('output.json', 'w') as outfile:
  24.     json.dump(new_json_object, outfile, ensure_ascii=False, indent=4)

你可以将原始JSON数据存储在名为file-1.json的文件中，然后运行这段代码以生成包含所需内容的新JSON文件。新文件将被命名为output.json。请确保你的Python环境中已经安装了JSON模块。

I am a beginner with JSON.

I have the following in my JSON file (file-1) :

  1. {
  2.     "Aps": [
  3.       {
  4.             "type": "opo",
  5.             "price_min": 7,
  6.             "price_max":10,
  7.             "app_time": 0,
  8.            
  9.             "arguments": {
  10.                 "prices": 15,
  11.                 "apps_num": "112"
  12.             },
  13.             "attributes": {
  14.             "name":"user1",
  15.             "priority":"100"
  16.             
  17.             } 
  18.     }
  19. }

How write python code that generates another JSON file that contain the same content of file-1 but duplicated 100 time in each time the name of user is different user2, user3 ... user100 and also it's priority.

I have tried the following but it is not working :

  2. for lp in range(100):
  3.     with open("sample.json", "w") as outfile:
  4.         outfile.write(json_object)

but it is not working ..

the required output is as follow :

  1. {
  2.     "Aps": [
  3.       {
  4.             "type": "opo",
  5.             "price_min": 7,
  6.             "price_max":10,
  7.             "app_time": 0,
  8.            
  9.             "arguments": {
  10.                 "prices": 15,
  11.                 "apps_num": "112"
  12.             },
  13.             "attributes": {
  14.             "name":"user1",
  15.             "priority":"100"
  16.             
  17.             } 
  18.     }, 
  19.       {
  20.             "type": "opo",
  21.             "price_min": 7,
  22.             "price_max":10,
  23.             "app_time": 0,
  24.            
  25.             "arguments": {
  26.                 "prices": 15,
  27.                 "apps_num": "112"
  28.             },
  29.             "attributes": {
  30.             "name":"user2",
  31.             "priority":"90"
  32.             
  33.             } 
  34.     },
  35.    {
  36.             "type": "opo",
  37.             "price_min": 7,
  38.             "price_max":10,
  39.             "app_time": 0,
  40.            
  41.             "arguments": {
  42.                 "prices": 15,
  43.                 "apps_num": "112"
  44.             },
  45.             "attributes": {
  46.             "name":"user2",

我用json和copy模块编写了一小段代码。

json用于读取和写入json文件。

copy是因为我在处理引用变量时遇到了一些问题，可以参考copy的文档；如果我更改了'temp'字典，它会影响'file'字典中的所有出现。

  1. import json
  2. import copy
  4. repeats = 100
  5. file = json.loads(open('file.json', 'r').read())
  6. temp1 = json.loads(open('file.json', 'r').read())['Aps'][0]
  7. for repeat in range(repeats):
  8.     temp = copy.deepcopy(temp1)
  9.     temp['attributes']['name'] = f"user{repeat + 2}"
  10.     temp['attributes']['priority'] = f"{repeat*10+100 - repeat*20}"
  11.     file['Aps'].append(temp)
  12.     temp1 = copy.deepcopy(temp)
  13. json.dump(file, open('file1.json', 'w'), indent=4)
英文:

I made a little code here using json and copy module

json for reading and writing json files

copy because I had some trouble with reference variables see documentation for copy; if I changed 'temp' dict then it would affect all occurrences in 'file' dict

  1. import json
  2. import copy
  4. repeats = 100
  5. file = json.loads(open('file.json', 'r').read())
  6. temp1 = json.loads(open('file.json', 'r').read())['Aps'][0]
  7. for repeat in range(repeats):
  8.     temp = copy.deepcopy(temp1)
  9.     temp['attributes']['name'] = f"user{repeat + 2}"
  10.     temp['attributes']['priority'] = f"{repeat*10+100 - repeat*20}"
  11.     file['Aps'].append(temp)
  12.     temp1 = copy.deepcopy(temp)
  13. json.dump(file, open('file1.json', 'w'), indent=4)

你应该首先将你的JSON文件转换为一个Python对象（字典）：

  1. import json
  3. file = open('sample.json')
  4. data = json.load(file)
  5. file.close()

现在你可以对你的Aps列表执行操作，比如将第一个对象追加到列表中100次：

  1. for dups in range(100):
  2.     data['Aps'].append(data['Aps'][0])

然后，你可以再次将你的字典保存到JSON文件中：

  1. with open("sample.json", "w") as outputfile:
  2.     json.dump(data, outputfile)
英文:

You should first convert your json file to a python object (dict):

  1. import json
  3. file = open('sample.json')
  4. data = json.load(file)
  5. file.close()

Now you can do stuff with your Aps list, like appending the first object 100 times to your list.

  1. for dups in range(100):
  2.     data['Aps'].append(data['Aps'][0])

Then you save your dict to a json file again:

  1. with open("sample.json", "w") as outputfile:
  2.     json.dump(data, outputfile)
