GIS ArcMap Raster Calculator with a python code

0

I'm trying use raster calculator that can export a raster to do different average values for for multiple layers. For example, I want to do averages for only the values and layers that are greater than 0. I'm trying to input a python code but it keeps failing. Here is a video where I try and explain my project if you guys need more context. https://www.youtube.com/watch?v=bt6ecPGjjDA&t=24s

Here is the python code that won't work. Maybe this is too simple for what I'm trying to accomplish.

Please any feedback will greatly help me! Super desperate for solutions at this point.

import arcpy
... from arcpy.sa import *
... f1 = arcpy.Raster("S:/npenme2/FaunalyzeFeature_KB3_Right_Radius_14497/value")
... f2 = arcpy.Raster("S:/npenme2/FaunalyzeFeature_KB1_Right_Radius_14471_RC11/value")
... f3 = arcpy.Raster("S:/npenme2/FaunalyzeFeature_KB4_Right_Radius_14510/value")
... if value > 1:
... outraster = (f1 + f2 + f3)/3
... else:
... outraster = (f1 + f2 +f3)/3 - 1
...
...
... outraster.save("S:/npenme2/Faunalyze/rasterCalc")
...

  I've also tried SQL on the actual raster calculator tool with this query. But it too does not work: Con("Feature_KB3_Right_Radius_14497" + "Feature_KB4_Right_Radius_14510" + "Feature_KB1_Right_Radius_14471_RC11">0,(("Feature_KB3_Right_Radius_14497" + "Feature_KB4_Right_Radius_14510" + "Feature_KB1_Right_Radius_14471_RC11")/3), ("Feature_KB3_Right_Radius_14497" + "Feature_KB4_Right_Radius_14510" + "Feature_KB1_Right_Radius_14471_RC11")/3-1))
