Python 从一个 json 文件中减去 json 对象（如果它们出现在另一个 Z466DEEC76ECDF5FCA6D38571F6324Z 文件中）

Question

I'd like to be able to remove objects from one json file if they contain a key:value pair that matches another json file.

File1:

[
  {
    "Admin": "aaa",
    "id": "111",
    "osType": "Windows",
    "publicIps": [],
    "resourceGroup": "bbb",
    "vmName": "example1"
  },
  {
    "Admin": "aaa",
    "id": "222",
    "osType": "Windows",
    "publicIps": [],
    "resourceGroup": "bbb",
    "vmName": "example2"
  },
  {
    "Admin": "aaa",
    "id": "333",
    "osType": "Windows",
    "publicIps": [],
    "resourceGroup": "bbb",
    "vmName": "example3"
  },
  {
    "Admin": "aaa",
    "id": "444",
    "osType": "Windows",
    "publicIps": [],
    "resourceGroup": "bbb",
    "vmName": "example4"
  },
]

File2:

[
 [
  {
   "vmName": "example1"
  }
 ],
 [
  {
   "vmName": "example2"
  }
 ],
 [
  {
   "vmName": "example3"
  }
 ],
]

Desired result in file3(or modified file1):

[
  {
    "Admin": "aaa",
    "id": "444",
    "osType": "Windows",
    "publicIps": [],
    "resourceGroup": "bbb",
    "vmName": "example4"
  },
]

I have found a few ways to remove elements from my first file, but I want to remove the entire object based on if it's k:v matches the any k:v in file2, I'm unaware of any way to do that.

Answer 1

Solution:

def return_non_repetitive_records(file1, file2):
    result = file1.copy()
    for i in range(len(file2)):
        for j in range(len(result)):
            if result[j]['vmName'] == file2[i][0]['vmName']:
                result.pop(j)
                break
    return result

Usage:

file3 = return_non_repetitive_records(file1, file2)

Result:

[{'Admin': 'aaa',
  'id': '444',
  'osType': 'Windows',
  'publicIps': [],
  'resourceGroup': 'bbb',
  'vmName': 'example4'}]

The Data You Provided:

file1 = [
  {
    "Admin": "aaa",
    "id": "111",
    "osType": "Windows",
    "publicIps": [],
    "resourceGroup": "bbb",
    "vmName": "example1"
  },
  {
    "Admin": "aaa",
    "id": "222",
    "osType": "Windows",
    "publicIps": [],
    "resourceGroup": "bbb",
    "vmName": "example2"
  },
  {
    "Admin": "aaa",
    "id": "333",
    "osType": "Windows",
    "publicIps": [],
    "resourceGroup": "bbb",
    "vmName": "example3"
  },
  {
    "Admin": "aaa",
    "id": "444",
    "osType": "Windows",
    "publicIps": [],
    "resourceGroup": "bbb",
    "vmName": "example4"
  },
]


file2 = [
 [
  {
   "vmName": "example1"
  }
 ],
 [
  {
   "vmName": "example2"
  }
 ],
 [
  {
   "vmName": "example3"
  }
 ],
]
