This is the third part of a series about the Flask framework, a common tool used to create web applications with Python.

Objectives

The part 3 will focus on connecting the web API with a local database.
The full example is available here: Python-Flask.

Topics

• Local Database

Local Database

Create another Python file inside the api folder called db_api and write this code:

The functions below must be created as well:

• Creates the database

• Creates tables

• Executes the operation

• Starts the database. This function must be called before app.run().

Finally, run the following command:

python .\api\db_api.py

The test.db will be created inside the api folder and will contain the user table:

Copy and modify the HTTP functions from api.py to db_api.py.

• POST

• PUT

• GET

• DELETE

Test each one and see the result.

We will connect our web API with a remote database.
