ArcGIS plug-in (Add-ins) can make it easier for users to customize and extend ArcGIS Desktop applications. It creates a series of custom tools to provide an open basic framework, packaged and compressed into a single file. Add-ins can be easily shared among users because they require neither an installer nor Component Model (COM) registration. This article records the process of implementing Python-based Arcgis plug-in development.

1. Prepare the Python add-in tool

Download the Python Add-in Wizard.

2. Create an add-in tool

(1) Create a working directory
After decompressing the "Python Add-in Wizard", create a working directory named "work2" in the addin_assistant directory to store the plug-in project files.

    df =arcpy.mapping.ListDataFrames(mxd)[0]
