A **virtual environment** is a directory with some files in it.

This page will teach you how to use **virtual environments** and how they work.

If you are ready to adopt a **tool that manages everything** for you (including installing Python), try [uv](https://github.com/astral-sh/uv).

First, create a directory for your project.

## Configure the `entrypoint` in `pyproject.toml` { #configure-the-entrypoint-in-pyproject-toml }

As your FastAPI `app` object lives in `app/main.py`, you can configure the `entrypoint` in your `pyproject.toml` file like this:

```toml
[tool.fastapi]
entrypoint = "app.main:app"
```

that is equivalent to importing like:

```python

Many packages that simplify it a lot have to make many compromises with the data model, database, and available features. And some of these packages that simplify things too much actually have security flaws underneath.

---

**FastAPI** doesn't make any compromise with any database, data model or tool.

It gives you all the flexibility to choose the ones that fit your project the best.
