Project

#Introducció

uv supports managing Python projects, which define their dependencies in a pyproject.toml file.

#Creating a new project

You can create a new Python project using the uv init command:

uv init hello
cd hello

Alternatively, you can initialize a project in the working directory:

mkdir hello
cd hello
uv init

uv will create the following files:

├── .gitignore
├── .python-version
├── README.md
├── main.py
└── pyproject.toml

The main.py file contains a simple “Hello world” program. Try it out with uv run:

uv run main.py

#Project structure

A project consists of a few important parts that work together and allow uv to manage your project.

In addition to the files created by uv init, uv will create a virtual environment and uv.lock file in the root of your project the first time you run a project command, i.e., uv run, uv sync, or uv lock.

…

#Managing dependencies

You can add dependencies to your pyproject.toml with the uv add command.

This will also update the lockfile and project environment:

uv add polars
