ArcMap Raster Calculator with Python code

Question

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 Python code but it keeps failing. Here is a video where I try and explain my project if you need more context. https://www.youtube.com/watch?v=bt6ecPGjjDA&t=24s

I've also tried putting single quotes on the line but there is still a syntax error.

>>> import arcpy
... from arcpy.sa import *
... f1 = arcpy.Raster("S:/npenme2/Faunalyze\Feature_KB3_Right_Radius_14497/value")
... f2 = arcpy.Raster("S:/npenme2/Faunalyze\Feature_KB1_Right_Radius_14471_RC11/value")
... f3 = arcpy.Raster("S:/npenme2/Faunalyze\Feature_KB4_Right_Radius_14510/value")
... if value > 1:
... outraster = (f1 + f2 + f3)/3
... else:
... outraster = (f1 + f2 +f3)/3 - 1
... f123 = f1 + f2 + f3
... outraster = Con(f123 > 0, f123 / 3, f123 / 3 - 1)
... outraster.save(S:/npenme2/Faunalyze/rasterCalc)
... 
Parsing error SyntaxError: invalid syntax (line 12)

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)) 

Answer 1

The error tells you exactly what is wrong and where IndentationError: expected an indented block (line 7). You need to indent lines in your if clause:

if value > 1:
 outraster = (f1 + f2 + f3)/3
else:
 outraster = (f1 + f2 +f3)/3 - 1

However, this code won't do what you want it to. You need to use Con:

f123 = f1 + f2 + f3
outraster = Con(f123 > 0, f123 / 3, f123 / 3 - 1)
outraster.save('S:/npenme2/Faunalyze/rasterCalc')

• Neharika Penmetcha: Thank you and sorry I accidentally copied my previous edit. I fixed the indentation error. I added the con statement but I'm still getting an error. I updated my question.
• user2856: The if value > 1 won't work, that is what the Con replaces, remove it. Also, you didn't quote the filepath, see edit.
