Arcmap python code#

In the next line, add a Display Name for an Attribute and set the Data Type to Field.

Click just below Data Type and select Feature Layer.

Remember that this can be either a file path or the name of a layer loaded into ArcGIS (ArcGIS will save the file to a temporary location and then load the output from a file into a new layer). Start by clicking just under Display Name and giving the first parameter a good name like Input Layer.

The next dialog is for defining the parameters going into your script.

You may want to check Show commend window when executing script at least for debugging.

In the dialog that appears, browse to your script file.

Make sure that Store relative path names is checked or you will not be able to move your tools to a different folder and click Next.

Give the script and appropriate name and label.

Right click on the new toolbox and select 'Add->Script.'.

You may not be able to distribute it because you won't be able to find it! Instead, create the tool under a 'Folder Connection' to a folder you can easily find. This folder is in your 'Documents and Settings' folder and may be hidden from you. Note: If you want to distribute your tool, DO NOT create it under 'My Toolboxes'.

This is a more sophisticated way to add Python scripts to ArcMap and we'll talk about them after we do the simple approach. This may seem strange but do not select 'New -> Python Toolbox'.Right-click on 'My Toolboxes' and select 'New -> Toolbox'.TheFirstParameter=arcpy.GetParameterAsText(0)ДЄrcpy.AddMessage('TheFirstParameter='+TheFirstParameter)

Enter this code and then continue creating the tool. The code below will read in the first parameter show it as a message in a dialog box. Your Python script will read the values of the parameters into variables you can use in your script. The major difference is that you'll need to read in the parameters the user sets in the tool dialog. Scripts for toolbox tools are very similar to regular Python scripts we've been created. Create a script to be used in the toolbox For now, use the user interface elements provided by Esri and we'll talk about using other UI elements in the future. Note: Python has some capabilities to create user interface elements like dialog boxes but ESRI no longer supports having developers add extensions to ArcGIS that have complex user interfaces.

Once you've created a Python script you can save it as a new toolbox function and even create a tool button for it. Creating Custom Tools with Python Scripts
