AddLayer is an easy way to add a layer or group layer into a map document.

Add Field adds a field to the input table—it doesn't create a new output table. The tool creates output using information in other parameters, such as the Create Feature Class tool. With the Create Feature Class tool, you specify the workspace and the name of the new feature class, and the feature class is created for you.polyline = arcpy.Polyline(array, spatial_reference) cursor.insertRow([polyline]) As shown above, a single geometry part is defined by an array of points.

The best way to interact with field mapping in Python scripting is with the FieldMappings object.

Right-click the new field and select Field Calculator. Set the Parser to Python.The Input Join Field and the Output Join Field can have different names. If a join field has the same name as a field from the input table, the joined field will be appended by _1 (or _2, or _3, and so on) to make it unique. If values in the Output Join Field are not unique, only the first occurrence of each value will be used.For starters, what if you don't run it from the script tool dialog but call the script from a command prompt, batch file, or another script?
