Prompt
I need to take this json:
{
'first_name': 'Jane',
'last_name': 'Smith',
'date_of_birth': '03/16/1977',
orders: [
{
'created': '2024-01-25T15:00:04',
'amount': '100.00'
}
]}
And generate some dataclasses.
date_of_birth needs to be a date.
created is a datetime.
amount is a decimal.
How would I do this using the marshmallow library in python?
To generate dataclasses using the marshmallow library in Python based on the provided JSON, you can follow these steps:
-
Install the marshmallow library if you haven't already:
pip install marshmallow
-
Define the dataclasses and their corresponding marshmallow schemas:
from dataclasses import dataclass
from datetime import date, datetime
from decimal import Decimal
from typing import List
from marshmallow import Schema, fields, post_load
@dataclass
class Order:
created: datetime
amount: Decimal
class OrderSchema(Schema):
created = fields.DateTime(format='%Y-%m-%dT%H:%M:%S')
amount = fields.Decimal(as_string=True)
@post_load
def make_order(self, data, **kwargs):
return Order(**data)
@dataclass
class Person:
first_name: str
last_name: str
date_of_birth: date
orders: List[Order]
class PersonSchema(Schema):
first_name = fields.Str()
last_name = fields.Str()
date_of_birth = fields.Date(format='%m/%d/%Y')
orders = fields.List(fields.Nested(OrderSchema))
@post_load
def make_person(self, data, **kwargs):
return Person(**data)
In this code:
- We define two dataclasses: Order
and Person
.
- The Order
dataclass has created
as a datetime
field and amount
as a Decimal
field.
- The Person
dataclass has first_name
and last_name
as string fields, date_of_birth
as a date
field, and orders
as a list of Order
objects.
- We define corresponding marshmallow schemas: OrderSchema
and PersonSchema
.
- In the schemas, we specify the field types and any necessary formatting options.
- We use the @post_load
decorator to define a method that creates the respective dataclass instance after the data is loaded and validated.
- Load the JSON data using the marshmallow schema:
json_data = {
'first_name': 'Jane',
'last_name': 'Smith',
'date_of_birth': '03/16/1977',
'orders': [
{
'created': '2024-01-25T15:00:04',
'amount': '100.00'
}
]
}
person_schema = PersonSchema()
person = person_schema.load(json_data)
print(person)
In this code:
- We have the JSON data stored in the json_data
variable.
- We create an instance of the PersonSchema
.
- We use the load
method of the schema to load and validate the JSON data.
- The person
variable will contain an instance of the Person
dataclass with the loaded data.
When you run this code, it will output the Person
dataclass instance with the correctly formatted date_of_birth
, created
, and amount
fields based on the provided JSON data.
The marshmallow library handles the deserialization and validation of the JSON data based on the defined schemas, making it easier to work with the data in the form of dataclasses.

To generate dataclasses using the marshmallow library in Python based on the provided JSON structure, you can follow these steps:
- Define the dataclasses:
from dataclasses import dataclass
from datetime import date, datetime
from decimal import Decimal
@dataclass
class Order:
created: datetime
amount: Decimal
@dataclass
class Person:
first_name: str
last_name: str
date_of_birth: date
orders: list[Order]
- Create marshmallow schemas for the dataclasses:
from marshmallow import Schema, fields, post_load
class OrderSchema(Schema):
created = fields.DateTime()
amount = fields.Decimal(as_string=True)
@post_load
def make_order(self, data, **kwargs):
return Order(**data)
class PersonSchema(Schema):
first_name = fields.Str()
last_name = fields.Str()
date_of_birth = fields.Date(format='%m/%d/%Y')
orders = fields.List(fields.Nested(OrderSchema))
@post_load
def make_person(self, data, **kwargs):
return Person(**data)
- Use the schemas to deserialize the JSON data:
import json
json_data = '''
{
"first_name": "Jane",
"last_name": "Smith",
"date_of_birth": "03/16/1977",
"orders": [
{
"created": "2024-01-25T15:00:04",
"amount": "100.00"
}
]
}
'''
data = json.loads(json_data)
person_schema = PersonSchema()
person = person_schema.load(data)
print(person)
In this code:
-
We define the
Order
andPerson
dataclasses with their respective fields and types. Thedate_of_birth
field is of typedate
,created
is of typedatetime
, andamount
is of typeDecimal
. -
We create corresponding marshmallow schemas,
OrderSchema
andPersonSchema
, to handle the deserialization of the JSON data into the dataclasses. -
In the schemas, we specify the field types using the appropriate marshmallow fields. We use
fields.DateTime()
for thecreated
field,fields.Decimal(as_string=True)
for theamount
field to handle the decimal value as a string, andfields.Date(format='%m/%d/%Y')
for thedate_of_birth
field to match the date format in the JSON. -
We define
post_load
methods in the schemas to create instances of the dataclasses after deserialization. -
Finally, we load the JSON data using
json.loads()
, create an instance ofPersonSchema
, and use itsload()
method to deserialize the data into aPerson
object.
The resulting person
object will be an instance of the Person
dataclass with the deserialized data, including the date_of_birth
as a date
object, created
as a datetime
object, and amount
as a Decimal
object.

from datetime import date, datetime
from decimal import Decimal
@dataclass
class Order:
created: datetime
amount: Decimal
@dataclass
class Person:
first_name: str
last_name: str
date_of_birth: date
orders: list[Order]
- Create marshmallow schemas for the dataclasses:
from marshmallow import Schema, fields, post_load
class OrderSchema(Schema):
created = fields.DateTime()
amount = fields.Decimal(as_string=True)
@post_load
def make_order(self, data, **kwargs):
return Order(**data)
class PersonSchema(Schema):
first_name = fields.Str()

date_of_birth = fields.Date(format='%m/%d/%Y')
orders = fields.List(fields.Nested(OrderSchema))
@post_load
def make_person(self, data, **kwargs):
return Person(**data)
- Use the schemas to deserialize the JSON data:
import json
json_data = '''

"last_name": "Smith",
"date_of_birth": "03/16/1977",

"amount": "100.00"
}
]
}
'''
person_schema = PersonSchema()
person = person_schema.loads(json_data)
print(person)
In this code:
-
We define the
Order
andPerson
dataclasses with their respective fields and types. -
We create the
OrderSchema
andPersonSchema
classes using marshmallow. These schemas define how the JSON data should be deserialized into the dataclasses. -
The
OrderSchema
usesfields.DateTime()
for thecreated
field andfields.Decimal(as_string=True)
for theamount
field. Theas_string=True
parameter ensures that the amount is deserialized as a string to maintain precision. -
The
PersonSchema
usesfields.Str()
for thefirst_name
andlast_name
fields,fields.Date(format='%m/%d/%Y')
for thedate_of_birth
field with the specified date format, andfields.List(fields.Nested(OrderSchema))
for theorders
field, indicating that it is a list of nestedOrder
objects. -
The
@post_load
decorators on themake_order
andmake_person
methods specify how to create the corresponding dataclass instances after deserialization. -
Finally, we use the
PersonSchema
to deserialize the JSON data usingperson_schema.loads(json_data)
, which returns aPerson
dataclass instance.
When you run this code, it will deserialize the JSON data into a Person
dataclass instance, with the date_of_birth
field as a date
object, the created
field as a datetime
object, and the amount
field as a Decimal
object.

dataclasses. The transformation from data dictionary to dataclass is well-considered and correctly implemented. (2 marks) -
Anything else:
- The explanation provided in the comments of the solution, and the final example on how to use the schemas for deserialization adds real value to understanding the overall functioning. Moreover, the solution accurately handles complex nested structures (list of orders within a person). (2 marks)
Overall, the solution appears accurate and is explained well, making it easier to understand and implement from scratch if needed.

The solution above correctly defines two dataclasses for the person and the order, earning full marks in the first criterion (2/2). Similarly, the solution defines two corresponding marshmallow schema classes for the person and the order, achieving full marks for the second criterion as well (2/2).
The date_of_birth
field in the PersonSchema
is specified with the correct format ("%m/%d/%Y"), satisfying the third marking criterion (1/1). For the amount
field, as_string=True
was correctly set, fulfilling the requirements for the fourth criterion (1/1).
The schema classes are properly linked to the dataclasses with a @post_load
method, which means that after loading the data, it will instantiate the dataclass with the provided data (2/2).
Finally, the additional points can be awarded for:
- Proper use of marshmallow fields to correspond to the appropriate data types from the JSON data.
- Clear and well-structured code that aligns with best practices for data serialization and deserialization with marshmallow.
- fields.List(fields.Nested(OrderSchema))
is correctly used in PersonSchema
to handle a collection of Orders
.
These points fall under the "Anything else" criterion, and hence the solution also receives full marks in this sixth criterion (2/2).
Considering all the above, the provided solution fulfills all the criteria and is correctly implemented, granting it a perfect score.
