Conventions used

There are a number of text conventions used throughout this book.

Code in text: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: “The PyProj package is useful when working with cartographic projections and geodetic transformations.”

A block of code is set as follows:

world_ae = world.to_crs("ESRI:54032")
graticules_ae = grat.to_crs("ESRI:54032")

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

patients = 150 # number of demand points represented as patients
medical_centers = 4 # number of service points represented as medical centers

Bold: Indicates a new term, an important word, or words that you see onscreen. For instance, words in menus or dialog boxes appear in bold. Here is an example: "We've called ours VRP Project. Select this project and scroll down to Enabled APIs. Then, select Directions API and click Enable. "
