Python 101
Why Python?
• ESRI has embraced Python for ArcGIS 10
• Python is the language that fulfills the needs of our user
community
– Easy to learn
– Excellent for beginners and experts
– SitblfSuitable for l arge proj ect s or small scri itpts
– CrossCross--platformplatform
Python 101
• Clear, easy to read syntax
• Easy to use, makes it simple to get started
• Variety of basic data types
– Including lists and dictionaries
• Comes with a large standard library
• Supports raising and catching exceptions
• Code can be grouped into modules and packages
• SStbjtupports object--ororitdiented programmi ng

Python at 10 .0
• ESRI has fully embraced Python as its language for
automation
1. ArcPy sitesite--packagepackage
– Includes mapping and Map Algebra support
– essor to the arcgisscripting module
2. Python window
– Python access and interaction from within ArcGIS
3. Python script tool framework

ArcPy 101
What is ArcPy?
• A cornerstone for automation in ArcGIS
– data analysis
– data conversion
– data management
– map automation
• ArcPy is a native Python site-site-packagepackage
– Access to 800 + geoprocessing tool
