PYTHON AND ARCGIS 10.1

What is Python Open source scripting/programming language Not compiled, uses interpreter

Slower performanceFaster development

Executes independentlyor inside ArcGISCan be run as scheduled

task or batch jobCan be packaged as ArcTool, Add-in, ToolboxModular language, available functionality depends

on loaded libraries

Python in ArcGIS = Arcpy Used to automate geoprocessing and

map creation Easily share tools Expand native tools

How does Python work? Write some code:

Where?○ Integrated Python Window, IDE○ Popular IDE: IDLE, PythonWin, PyScripter○ Code Editor: Bluefish, ConTEXT, Notepad ++○ Model Builder*○ Pre-written code – Arcpy café, other users, ect…

What?○ Create and automate workflows○ Extend tools to include logic○ Write you own tools○ Access other module to analyze your data○ Python Toolbox

How does Python work…cont. Run Code:

How?○ Add script to a toolbox○ Attach script to a custom toolbar button○ Schedule using Windows Scheduler○ Run from IDE○ As a toolbox○ Expand logic in custom labels
