This course teaches how to create Python scripts to automate ArcGISgeoprocessing tasks, increasing productivity and efficiencies in GIS workflows. I am looking to create a geoprocessing tool using python in arcGIS 10.2 that will be used in the ArcGIS online web app builder. In Python, sys.argv provides an alternative for reading parameter values. Every Python toolbox tool parameter has an associated data type. I've been coding with Python for several months now and have developed some reasonably complex scripts for primarily geoprocessing tasks. The example above could be rewritten to use sys.argv as below. Ask and thou shalt receive… Well it seems as though there is a LOT of interest out there in Python Geoprocessing for ESRI ArcView 9.x. Python syntax rules will enforce most geoprocessing conventions when naming aPython toolbox tool class. Python is initially only aware of tools stored in ArcGIS system toolboxes like the Data Management Tools, Conversion Tools, and Analysis Tools toolboxes. Tells Python to import basic ArcGIS geoprocessing functionality. *** ** Example: Tells Python to import functionality from ArcGIS Spatial Analyst. The display name for the script tool (as shown in the Geoprocessing pane) and can contain spaces. A Python toolbox (.pyt) is an ASCII file that can be edited in any text editor or click the Project tab, click Options, click Geoprocessing, and edit Script Editor. The name is used when the script tool is run from Python. Every script tool parameter has an associated data type.
