# Use Python venv

Python venv is Python Virtual Environment. Why do we need to use Python venv ? Because we don't want to mess up with Python packages which are stored in different location: system directories, user directories, ...

Assume you use Python 3 and Linux.

Python venv stores everything in a local directory.

Inside a directory, run:

```sh
python -m venv venv
```

Now you can use venv with:

```sh
source ./venv/bin/activate
```
