isn't user = 1 here in the example u input?

while in if check ur checking for user == 2

!e

import json
user = 2
class Car:
    #Defining the class car that takes paramters\
    #registration number, year of production, passenger , vehicle mass
    def __init__(self,number, year, passenger, mass):
        self.registration_number= number
        self.year_of_production= year
        self.passenger = passenger
        self.vehicle_mass= mass

def decod(obj):
    return Car(obj['registration_number'], obj['year_of_production'],obj['passenger'],obj['vehicle_mass'] )
#create new car object
MyCar=Car(number="ABC1234",year=2024,passenger=True, mass=19432 )



#produce a json string descring the vehicle
try:
    json_str= json.dumps(MyCar, default= lambda o: o.__dict__)
except TypeError:
    print(f'Object {MyCar.__class__.__name__} is not serializable')
else:
    print(f'The resulting JSON string is :\n {json_str}')

if user ==2:
    json_decoded= json.loads(json_str, object_hook = decod)
    print(json_decoded.__dict__)

:white_check_mark: Your 3.12 eval job has completed with return code 0.

001 | The resulting JSON string is :
002 |  {"registration_number": "ABC1234", "year_of_production": 2024, "passenger": true, "vehicle_mass": 19432}
003 | {'registration_number': 'ABC1234', 'year_of_production': 2024, 'passenger': True, 'vehicle_mass': 19432}

[mystic gazelle]

yep

wrong key in decode and user = 2 u need to fix

[fresh elbow]

ok

[fresh elbow]

could you please be more explicity if you don't mind ? Thanks you

[mystic gazelle]

in ur case
if user == 2 was false

u set user to 1 in ur input

so it wasn't evaluating at all

and in decod function u had obj['mass'] which is wrong it should be obj['vehicle_mass']

[fresh elbow]

thANKS A LOT
