Python Objects to JSON String

Python provides a easy way to handle JSON, by importing thejson module, one can easily encode a list of dicts or a dict of dicts so on, but there is a easy trick to generate a JSON or even a nested JSON string from an object of a class.

json.dumps(obj[, skipkeys[, ensure_ascii[, check_circular[, allow_nan[, cls[, indent[, separators[, encoding[, default[, **kw]]]]]]]]]])`=> Serialize obj to a JSON formatted str

Consider an example, classic class called Student with few attributes like email,contact,name,skills,edu. Which are updated by other methods or at object creation.

class Student:

def init(self,name,email,contact,skills,ug=None,pg=None):

    self.email=email
    self.contact=contact
    self.name=name
    self.skills=[skills]

    self.edu={"ug":[ug],"pg":[pg]} 

Creating an instance of that class and prints the vars() we get something like :

james=Student("James","[email protected]","","+1 7789990007","Python","CS", "CS")

print vars(james) {

'skills': ['Python'],
'contact': '+1 7789990007',
'email': '[email protected]',
'edu': {
    'ug': ['CS'],
    'pg': ['CS']
},
'name': 'James'

}

import json print json.dumps(vars(james),sort_keys=True, indent=4)

{

"contact": "+1 7789990007", 
"edu": {
    "pg": [

        "CS"
    ], 
    "ug": [
        "CS"
    ]

}, 
"email": "[email protected]", 
"name": "James", 
"skills": [

    "Python Ruby"
]

}
