I tried using the Google Maps API in Python to perform route search.

The module used is googlemaps/google-maps-services-python

You can set up the environment with the following commands. While you’re at it, also install ipython.

2

pip install googlemaps
pip install ipython

You also need to apply for a Google API key, so go to Google APIs to apply and enable it.

If everything is fine up to this point, let’s try it out right away. Get route information by car from Totsuka Station to Odoriba Station.
