Working with packages is an important part of using Python in Hex.
Hex has a number of popular packages pre-installed.
You can see which packages are available through the Packages tab in the left-hand bar.
You can add new packages to a project using pip, much as you would in a local environment.
Create a new cell, and use a ! to trigger a terminal command:
!pip3 install astropy
Because projects are run top to bottom with a new kernel every time a user visits your App packages installed with !pip install
have to be reinstalled every time your project runs.
