Using GeoPy to Add GPS info to DepEd School Data

We have a list of DepEd Schools without any known Latitude, Longitude information. We reproduce a partial list of schools below:

deped_school_location_2021.csv

We follow the steps outlined here:

Python: OpenStreetMap API - add Longitudes and Latitudes by using Geopy module

We import the needed Python modules

Since we are using a free gateway, we need to throttle back the requests. I copied from this:
python 3.x — Error 502 while trying to use geopy and ArcGIS — Stack Overflow

And it has the bonus of appending the results to a file. In my case, I called the output file as GeoCodedSchools.csv
