Description
GPT-4-32k is an extended version of GPT-4, with the same capabilities but quadrupled context length, allowing for processing up to 40 pages of text in a single pass. This is particularly beneficial for handling longer content like interacting with PDFs without an external vector database. Training data: up to Sep 2021.
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 achieve this using the marshmallow library in Python, you can follow the steps below:
-
Install the marshmallow library if you haven't already:
pip install marshmallow
-
Import the necessary modules and create dataclasses for the given JSON structure.
-
Define Marshmallow schemas for your dataclasses and specify how the fields should be deserialized.
Here's an example of how to do this:
import json
from dataclasses import dataclass
from decimal import Decimal
from datetime import date, datetime
from marshmallow import Schema, fields, post_load
@dataclass
class Order:
created: datetime
amount: Decimal
@dataclass
class Person:
first_name: str
last_name: str
date_of_birth: date
orders: list[Order]
class OrderSchema(Schema):
created = fields.DateTime()
amount = fields.Decimal()
@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()
orders = fields.List(fields.Nested(OrderSchema))
@post_load
def make_person(self, data, **kwargs):
return Person(**data)
json_str = '''{
"first_name": "Jane",
"last_name": "Smith",
"date_of_birth": "03/16/1977",
"orders": [
{
"created": "2024-01-25T15:00:04",
"amount": "100.00"
}
]
}'''
loaded_json = json.loads(json_str)
person_schema = PersonSchema()
person = person_schema.load(loaded_json)
print(person)
In this example, Order and Person dataclasses are defined, along with their respective schemas using the marshmallow library. The post_load
decorators are used to create instances of the dataclasses after deserializing the input data.
Finally, the JSON string is deserialized into the Person dataclass instance (person
), with the specified field types correctly set (date, datetime, and decimal).
Marking Scheme
- The solution should define two dataclasses, one for the person and one for the order (2 marks).
- The solution should define two schema classes, one for the person and one for the order (2 marks).
- The solution should specify the date format for the
date_of_birth
field. (format="%m/%d/%Y") (1 mark) - The decimal field needs
as_string=True
. (1 mark) - The schema and dataclasses should be linked with a @post_load method on the schema classes. (2 marks)
- Anything else: (2 marks)

Final Evaluation:
{
"score": 8
}
The solution effectively demonstrates the use of the marshmallow library for deserialization into dataclasses, ensuring type correctness for datetime and lists, yet it slightly misses solving precisely as per the specified formatting and string representation for decimal types.
First, you need to install the marshmallow library if you haven't already:
pip install marshmallow
Next, you can create a Python script with the following code to define the data classes and use the marshmallow library for deserialization:
import datetime
import decimal
from typing import List
from dataclasses import dataclass
from marshmallow import Schema, fields, post_load
@dataclass
class Order:
created: datetime.datetime
amount: decimal.Decimal
@dataclass
class User:
first_name: str
last_name: str
date_of_birth: datetime.date
orders: List[Order]
class OrderSchema(Schema):
created = fields.DateTime()
amount = fields.Decimal()
@post_load
def make_order(self, data, **kwargs):
return Order(**data)
class UserSchema(Schema):
first_name = fields.Str()
last_name = fields.Str()
date_of_birth = fields.Date()
orders = fields.List(fields.Nested(OrderSchema))
@post_load
def make_user(self, data, **kwargs):
return User(**data)
json_string = """
{
"first_name": "Jane",
"last_name": "Smith",
"date_of_birth": "03/16/1977",
"orders": [
{
"created": "2024-01-25T15:00:04",
"amount": "100.00"
}]
}
"""
user_schema = UserSchema()
user = user_schema.loads(json_string)
print(user)
Replace the json_string
variable with the JSON string you want to deserialize.
This script defines data classes for User
and Order
, and creates schema classes to handle the deserialization with marshmallow. The @post_load
decorator is used to create the data class instances after loading the data.
Once you run the script, it will deserialize the JSON string into a User
object with the specified attributes.

- Dataclass Definition (2 marks)
-
The provided solution defines two dataclasses,
Order
andUser
, which includes all necessary attributes, including the collections and proper types (datetime and decimal). -
Schema Class Definition (2 marks)
-
Two schema classes (
OrderSchema
andUserSchema
) are correctly defined. They match the dataclasses in structure and provide fields matching the properties of each dataclass. -
Date Format Specification (0.5 marks)

should be specifically defined asformat="%m/%d/%Y"
, which is missing. The solution usesfields.Date()
without specifying serialization and deserialization formats. -
Decimal Field as String (0.5 marks)
-
The decimal field should be serialized back to a string using
as_string=True
, but this is missing in the provided solution. It only statesfields.Decimal()
. Includingas_string=True
would make it more faithful to the JSON structure for amounts which are in string format. -
Linking Schema and Dataclasses with @post_load (2 marks)
-
The
@post_load
decoratorsmake_order
andmake_user
are implemented correctly. They effectively convert the dictionary loaded from JSON back into instances of the dataclassesOrder
andUser
. -
Additional Elements (2 marks)
- Proper handling and conversion of JSON data through dataclasses and schema.
- The correct use of marshmallow for loading data from JSON and creating instances.
- Overall completeness and functionality of the code provided it is run in an appropriate environment.

The solution demonstrates a good understanding of using marshmallow with dataclasses, but misses two important details in the field specifications. Overall, it's a solid implementation that would work for most cases, but could be improved for more precise handling of date and decimal fields.
To use the Marshmallow library, you should first install it using pip:
pip install marshmallow
Then, you can create dataclasses and use Marshmallow schemas to deserialize the JSON string and validate the data types. Here's an example:
import datetime as dt
from decimal import Decimal
from dataclasses import dataclass
from typing import List
from marshmallow import Schema, fields, post_load
# Dataclasses
@dataclass
class Order:
created: dt.datetime
amount: Decimal
@dataclass
class Person:
first_name: str
last_name: str
date_of_birth: dt.date
orders: List[Order]
# Schemas
class OrderSchema(Schema):
created = fields.DateTime()
amount = fields.Decimal()
@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()
orders = fields.List(fields.Nested(OrderSchema))
@post_load
def make_person(self, data, **kwargs):
return Person(**data)
# Deserialize 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'
}
]
}
# Load data into dataclasses
person_schema = PersonSchema()
person = person_schema.load(json_data)
print(person)
# Deserialize JSON to a dictionary with validated data types
validated_data = person_schema.load(json_data)
print(validated_data)
In this example, we first define the dataclasses Order
and Person
. Then, we create Marshmallow schemas OrderSchema
and PersonSchema
to specify the validation rules and deserialization methods (post_load
methods used to create dataclasses).
Finally, we load the JSON data into the PersonSchema
using the load
method, which generates the Person
and Order
dataclass instances with the correct data types.

However, it misses two important details:
1. The date_of_birth
field should have specified the date format to match the input JSON.
2. The amount
field in OrderSchema
should have used as_string=True
to properly handle the decimal input.
These omissions could lead to errors when parsing the actual JSON data. Despite these issues, the solution provides a solid foundation and demonstrates a good understanding of using Marshmallow with dataclasses.
