You can view the complete notebook by clicking on the </> Code button to the left of Fig.\ref{234253}  below, then clicking on the file named   PintTest.ipynb . Doing so will open up the notebook in Jupyter webserver hosted by Authorea.  In some cases, Python notebooks such as these can be run and modified within the webserver. In this case, however, you must first download the code to your own computer, as Pint is not yet included in the Authorea's python installation.  Note about print formatting commands: the ~ command instructs Pint to output units in abbreviated form. The P command adds subscript and superscript formatting.  See the Pint tutorial.
