使用 indent 参数来定义缩进量

  1. import json
  2.  
  3. x = {
  4.   "name": "Bill",
  5.   "age": 63,
  6.   "married": True,
  7.   "divorced": False,
  8.   "children": ("Jennifer","Rory","Phoebe"),
  9.   "pets": None,
  10.   "cars": [
  11.     {"model": "Porsche", "mpg": 38.2},
  12.     {"model": "BMW M5", "mpg": 26.9}
  13.   ]
  14. }
  15.  
  16. # use four indents to make it easier to read the result:
  17. print(json.dumps(x, indent=4))
