Sending JSON

JSON isn't just something we get from the server, we can also send JSON data!

In Python, we use the json module which provides two main methods: json.loads() and json.dumps().

json.dumps()

json.dumps() is particularly useful for sending JSON.

As you may expect the JSON dumps() function does the opposite of loads. It takes a Python dictionary or list as input and converts it into a string. This is useful when we need to serialize the objects into strings to send them to our server or store them in a database.

import json

data: dict[str, str | bool] = {"name": "waseem", "chad": True}
json_string = json.dumps(data)
print(json_string)  # {"name": "waseem", "chad": true}
# only the boolean changed!

Assignment

Users need to be able to mark their projects as completed. However, update_project_by_id(project_id: str, project_obj: Project) -> Project is passing an invalid value to pyfetch, causing an error.

The body parameter in pyfetch expects a string when sending JSON data. You need to convert the Python dictionary to a JSON string before sending it.

Fix the code by converting the project_obj dictionary to a JSON string using json.dumps().
