How to install Python in a clean and easy way

Install uv

---

Run the following

brew install uv

This will install uv and its dependencies.

info

uv is a fast project manager for Python.

Then run the following to install python 3.11.9

uv install 3.11.9

Then go to your working directory for your current project and run the following

uv init

This will create a new Python project with a pyproject.toml file

Then run the following to add any dependency to your project

uv add fastapi

When you run uv add to add dependencies, uv will create a virtual environment if it doesn't already exist. This virtual environment is typically created in a .venv directory in your project root.

Then run any script using uv

uv run main.py

This way you will have the benefits of avoiding conflicts between python package dependencies and using virtual environments without having to think about it.
