Python implementation of complex objects to JSON method examples

In this article, examples of Python implementation of complex objects to JSON. Shared for your reference, as follows:

In Python for simple object to json is still relatively simple, as follows:

import json
d = {'a': 'aaa', 'b': ['b1', 'b2', 'b3'], 'c': 100}
json_str = (d)
print json_str

For complex objects, you can use the following methods to achieve this, for example:

import json
class Customer:
  def __init__(self, name, grade, age, home, office):
     = name
     = grade
     = age
     = Address(home, office)
  def __repr__(self):
    return repr((, , , , ))
class Address:
  def __init__(self, home, office):
     = home
     = office
  def __repr__(self):
    return repr((, , ))
customers = [
    Customer('john', 'A', 15, '111', 'aaa'),
    Customer('jane', 'B', 12, '222', 'bbb'),
    Customer('dave', 'B', 10, '333', 'ccc'),
    ]
json_str = (customers, default=lambda o: o.__dict__, sort_keys=True, indent=4)
print json_str

The results are as follows

[
  {
    "address": {
      "home": "111",
      "office": "aaa"
    },
    "age": 15,
    "grade": "A",
    "name": "john"
  },
  {
    "address": {
      "home": "222",
      "office": "bbb"
    },
    "age": 12,
    "grade": "B",
    "name": "jane"
  },
  {
    "address": {
      "home": "333",
      "office": "ccc"
    },
    "age": 10,
    "grade": "B",
    "name": "dave"
  }
]
