You should also see that `pip` is being installed by default.

 ### Checking `pip`
-First, let's check that we have `pip` installed. For CS41, we'll be using a package manager called `pip` to install and manage Python software packages. By default, Python 3.8.0 ships with a version of `pip` prebuilt. `pip` interacts very well with PyPI (the Python Package Index), so we'll be using `pip` extensively this quarter.
