这个例子，看了就明白了

# -*- coding:utf-8 -*-
# ! ./usr/bin/env python
 
import json
jsonpath = 'C:/Users/Administrator/Desktop/test.json'
 
data = {
  "carDark": {
    "name": "CarDark",
    "image_files": [
      "0001.jpg",
      "0002.jpg",
      "0003.jpg",
      "0004.jpg",
      "0005.jpg",
    ],
    "init_rect": [
      73,
      126,
      29,
      23
    ],
    }
}
 
# one line show
data1 = json.dumps(data)
 
# multi lines show as dict format
data2 = json.dumps(data, indent=2) # indent 表示缩进
 
# write to json file , one line show
with open(jsonpath, 'w') as f:
  json.dump(data, f)
 
# write to json file , multi lines show as dict format
with open(jsonpath, 'w') as f:
  json.dump(data, f, indent=2)
 
print(data1)
print(data2)
