删除 json 文件中所有出现的键

Question

How do I remove all occurrences of a key in a json file? In the example below I want to remove all of the "rating" keys.

How it is now:

{
  "player": {
    "rating": "99",
    "rarity": "super_rare"
  },
  "player2": {
    "rating": "87",
    "rarity": "rare"
  }
}

What I want:

{
  "player": {
    "rarity": "super_rare"
  },
  "player2": {
    "rarity": "rare"
  }
}

Answer 1

Try this:

import json

with open('data.json') as fp:
    data = json.loads(fp.read())
    for player in data.values():
        del player['rating']

with open('output.json', 'w') as fw:
    json.dump(data, fw, indent=4)

Output:

{'abc': {'rarity': 'super_rare'}, 'efg': {'rarity': 'rare'}}
