When working with a large FastAPI project, organizing your code into packages and using a modular file structure helps in maintaining scalability, readability, and ease of collaboration. package structure for a large FastAPI project: 1. Directory Structure my_fastapi_project/ │ ├── app/ │ ├── __init__.py │ ├── main.py # Main FastAPI application │ ├── models/ # Pydantic and ORM models │ │ ├── __init__.py │ │ └── movie.py # Movie model definition │ ├── api/ # API endpoints │ │ ├── __init__.py │ │ ├── v1/ # Versioned API (v1) │ │ │ ├── __init__.py │ │ │ └── movies.py # Endpoints for movies │ ├── core/ # Core settings, config, database connection, etc. │ │ ├── __init__.py │ │ └── config.py # Settings configuration │ ├── services/ # Business logic and services │ │ ├── __init__.py │ │ └── movie_service.py # Logic for movie-related actions │ └── db/ # Database-related files │ ├── __init__.py │ └── database.py # DB connection setup ├── tests/ # Test files │ ├── __init__.py │ └── test_movies.py # Test cases for movies API ├── .env # Environment variables ├── requirements.txt # Python dependencies └── README.md # Project documentation 2. Explanation of Directories and Files app/main.py: The entry point for your FastAPI application. This file initializes the app and includes middleware, routers, and other configurations. app/models/: Contains Pydantic models and ORM models (if you’re using a database like SQLAlchemy or Tortoise ORM). movie.py defines the Movie model, which might be a Pydantic schema or an ORM model. app/api/: Contains all the API routes organized by version (e.g., v1, v2). Inside each version, the routes are further organized by feature or resource. movies.py handles all the endpoints related to movies in version 1 of the API (e.g., /v1/movies/). app/core/: Contains application-wide settings, configurations, constants, and utilities. config.py manages application configurations like environment variables, API settings, etc. app/services/: Contains business logic and services related to different features of the application. movie_service.py might contain functions that handle complex business logic, such as interacting with the database, performing calculations, or managing caching, related to movies. app/db/: Handles database-related configurations and connection management. database.py manages the database connection setup, ORM initialization, and session handling. tests/: Contains unit and integration tests for your API, models, and services. test_movies.py contains test cases to ensure the correct functioning of movie-related API endpoints.

In the world of multimedia, videos are a valuable and versatile form of content. However, you may find yourself needing to break down a long video into smaller, more manageable segments for various purposes. This could be for editing, sharing, or simply to make the content more digestible. To automate this process, you can use FFmpeg, a powerful multimedia framework, along with a Python script. In this blog post, we’ll guide you through creating a Python script that segments a video and saves the segments in a dedicated folder. ...

Setting up a Python virtual environment in Linux involves a few steps. Here’s a step-by-step guide: Open a terminal: Launch the terminal application on your Linux distribution. Install Python: Most Linux distributions come with Python pre-installed. However, if it’s not installed or you want a specific version, you can install it using your distribution’s package manager. For example, on Ubuntu or Debian-based systems, you can use the following command to install Python 3: ...
