## [Virtualenv](https://virtualenv.pypa.io/en/latest/)
`virtualenv` is a tool to create isolated Python environments , The `venv` module does not offer all features of this library, venv is slower,not as extendable,-   is not upgrade-able via [pip](https://pip.pypa.io/en/stable/installation/),-   does not have as rich programmatic API (describe virtual environments without creating them).

### [Installation](https://virtualenv.pypa.io/en/latest/installation.html)

#### via pipx
```bash
pipx install virtualenv
virtualenv --help
```
other ways are not as good but if needed are in documentation

#### via [zipapp](https://docs.python.org/3/library/zipapp.html)

You can use Virtualenv without installing it too. pypa publish a Python [zipapp](https://docs.python.org/3/library/zipapp.html), you can just download this from [this link](https://bootstrap.pypa.io/virtualenv.pyz) and invoke this package with a python interpreter:

``` bash
python virtualenv.pyz --help
```
