如何从json文件中随机选择？

Question

我想使用其ID号从外部json文件中随机选择歌曲名称和艺术家：

[
 {
   "id": 1,
   "Song1": {
      "Song_nam": "killer queen"
   },
   "Song_artist": "queen"
},
 {
   "id": 2,
   "Song1": {
      "Song_nam": "Africa"
   },
   "Song_artist": "Toro"
},
 {
   "id": 3,
   "Song1": {
      "Song_nam": "Perfect"
   },
   "Song_artist": "Ed sheeran"
}
]

Answer 1

“ songs.json” 内容：

[
{
  "id": 1,
  "Song1": {
    "Song_nam": "killer queen"
  },
  "Song_artist": "queen"
},
{
  "id": 2,
  "Song1": {
    "Song_nam": "Africa"
  },
  "Song_artist": "Toro"
}, 
{
  "id": 3,
  "Song1": {
    "Song_nam": "Perfect"
  },
  "Song_artist": "Ed sheeran"
}
]

代码：

import json
from random import choice

with open("songs.json") as f:
    content = json.loads(f.read())

winner = choice(content)

print(json.dumps(winner, indent=4))

输出：

{
    "id": 2,
    "Song1": {
        "Song_nam": "Africa"
    },
    "Song_artist": "Toro"
}
