As this book covers Python, it is assumed that the reader has a basic understanding of the Python language, can install Python libraries, and knows how to write and run Python scripts. As for additional knowledge, the first six chapters can easily be understood without any previous knowledge of geospatial data analysis. However, later chapters assume some knowledge of spatial databases, big data platforms, data science, web APIs, and Python web frameworks.

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

host="{my.host.com}", dbname="mapd")
cursor = connection.cursor()
sql_statement = """SELECT name FROM county;"""
cursor.execute(sql_statement)
Any command-line input or output is written as follows:
conda install -c conda-forge geos
Bold: Indicates a new term, an important word, or words that you see onscreen. For example, words in menus or dialog boxes appear in the text like this.
