I am facing this error time and again when I am try to read my img rasters and running a conditional statement. I am new to Python. The code ran for one raster that is without for loop but not later. Here is the code:

import arcpy, os
from arcpy import env
from arcpy.sa import *
env.overwriteOutput = True
arcpy.env.workspace = r"C:\Users\libpub\Desktop\try"
arcpy.CheckOutExtension('Spatial')

rasterlist = arcpy.ListRasters()
for raster in rasterlist:
    out1 = Con(('Raster')>0.2, 1, 0)
    print out1
    out1.save("C:\Users\libpub\Desktop\try")

print "done!"

The arcpy.ListRasters function returns a list of the raster names in your workspace. The Con function, in the format you are using, requires an input Raster object which can be created with:

rast = Raster('raster_name')

If you change out1 = Con(('Raster')>0.2, 1, 0) to out1 = Con(Raster(raster)>0.2, 1, 0) you should find it works. This is shown in the Con documentation in code example 1.
