The Python window is an interactive window that lets you enter Python code, execute it immediately, and view the results in your active map. In ArcGIS API for Python, geoprocessing toolboxes and tools within them are represented as Python module and functions within that module. For these tools, the corresponding function returns the multiple output values as a named tuple. ArcPy returns the output values of a tool as a Result object. Use Python Scripting for ArcGIS Pro to learn Python best practices to write useful scripts that work with spatial data in ArcGIS Pro. The event handler creates a FeatureSet from the clicked point geometry, and uses the string '5 Miles' as input for the viewshed_distance parameter instead of creating a LinearUnit object. ArcPy and the ArcGIS API for Python are complementary libraries; ArcPy allows you to use, automate, and extend desktop GIS, and the ArcGIS API for Python supports the same for Web GIS. A URL is used to connect to and use a geoprocessing service. You can write scripts that use ArcPy in conjunction with a diverse array of functions provided through Python's standard and third-party libraries. The geoprocessing service is now ready to be used in ArcGIS API for JavaScript. However you run Python, commands work fundamentally the same way and use the same geoprocessing tools. Each module has a handful of types and functions that are focused towards one aspect of the GIS. With your cursor at the end of the line of code, press Enter. All of the help topics for geoprocessing tools include Python examples.
