I am very new to Python.

I built a model in the Model Builder in a toolbox in ArcCatalog 10.3.1. I keep getting the following error about my buffer not being able to be executed and that my parameters are not valid. I set a field for a distance value for my buffer, my buffer, and a spatial join output as Model Parameters in my model builder before I exported the script to Python to run in Python IDLE:

Traceback (most recent call last):

File "F:\Projects\Working\HurricanesSCRIPT.py", line 49, in arcpy.Buffer_analysis(Hurricanes_in_Counties, Hurricanes_Buffer, v15_Miles, "FULL", "ROUND", "NONE", "", "PLANAR") File "C:\Program Files (x86)\ArcGIS\Desktop10.3\ArcPy\arcpy\analysis.py", line 692, in Buffer raise e ExecuteError: Failed to execute. Parameters are not valid. ERROR 000725: Output Feature Class: Dataset F:\Projects\Working\ModelProject\ModelData.gdb\Hurricanes_Buffer already exists. Failed to execute (Buffer).

I have already put in 'arcpy.env.overwriteOutput = True' just below # Import arcpy module import arcpy.

Here is the script for my arguments:

# Script arguments

v15_Miles = arcpy.GetParameterAsText(0) if v15_Miles == '#' or not v15_Miles: v15_Miles = "15 Miles" #15 Miles

Hurricanes_Counties_SpaJoi = arcpy.GetParameterAsText(1) if Hurricanes_Counties_SpaJoi == '#' or not Hurricanes_Counties_SpaJoi: Hurricanes_Counties_SpaJoi = "F:\Projects\Working\ModelProject\ModelData.gdb\Hurricanes_Counties_SpaJoi" # provide a default value if unspecified

Hurricanes_Buffer = arcpy.GetParameterAsText(2) if Hurricanes_Buffer == '#' or not Hurricanes_Buffer: Hurricanes_Buffer = "F:\Projects\Working\ModelProject\ModelData.gdb\Hurricanes_Buffer" # provide a default value if unspecified

And here is the script for my buffer:

# Process: Buffer

arcpy.Buffer_analysis(Hurricanes_in_Counties, Hurricanes_Buffer, v15_Miles, "FULL", "ROUND", "NONE", "", "PLANAR")
