You can use `async` or regular functions.

You would normally do this **once**, right after you create the virtual environment.

Make sure the virtual environment is active (with the command above) and then run:

```console

---> 100%
```

/// tip

Sometimes, you might get a **`No module named pip`** error when trying to upgrade pip.
