Introduction to Pandas
Pandas is a Python module used for data analysis and manipulation. It is an open-source module that can be installed and used separately from ArcGIS Pro; in fact, it is the most popular Python data analysis module. As it is so useful and well-known, it is included along with Python when ArcGIS Pro is installed.
Its origins lie in the financial world, where statistical analysis is used constantly. In 2007, needing a more powerful tool to perform quantitative analysis, a financial analyst and programmer named Wes McKinney developed the first version of Pandas. It was made open source in 2012 and was quickly recognized as a powerful and flexible data tool.
Pandas DataFrames
The basic data structure in Pandas is the Pandas DataFrame. A Pandas DataFrame is essentially a data table, much like ArcGIS attribute tables or Excel tables, but with a whole lot of built-in features that make it easy to manipulate and manage data.
