You should see a map with the topographic basemap layer centered on the Santa Monica Mountains in California. What's next? Learn how to use additional functionality in these tutorials:
The following code examples show how return values are captured and what their values could be: Return the path of the output feature class. The result can be used as input to another function. >>> result = arcpy.Buffer_analysis("rivers", "riverBuf", "50 METERS") ...
Adds a handler that gets called each time a certain addon settings value is changed by the user. You should ignore any settings changes which aren't supposed to be handled (TODO: clarify what this means).Example of handler:liquidity_sizes = {} # addon - entity received from create_addon ...
