Converting Code from VB to Python in Map Algebra

Question

I have a problem with Map Algebra in ArcMap 10 to convert some codes made by VB, so I need to convert it to python to work in ArcMap 10 without problem.

How do I deal with map algebra in ArcMap 10?

the code:

con([Direction to univer] > 0 & [Direction to univer] <= 180,[Direction to univer] + 180,[Direction to univer] - 180) 

Answer 1

You should be able to do the processing directly in python without much fuss:

import arcpy
from arcpy.sa import *
direction = Raster("direction-to-univer.tif")
output = con((direction > 0) & (direction <= 180), direction + 180, direction)
output.save("conned.tif")
