I'm confused. If you know the file name, why not just substitute the file name for "_stanislaus.img"?import arcpy
import sys, os, string
from arcpy.sa import *
from arcpy import env
arcpy.env.workspace = "D:\Project\Stanislaus\Timeseries\NDVI"
LstRst = arcpy.ListRasters("*", "img")
for Rst in LstRst:
Img1 = string.find(Rst, "aug08_2010_stanislaus.img")
if Img1 > -1:
print Rst
Or, are you looking for how to substitute a variable into the file name?import arcpy
import sys, os, string
from arcpy.sa import *
from arcpy import env
arcpy.env.workspace = "D:\Project\Stanislaus\Timeseries\NDVI"
LstRst = arcpy.ListRasters("*", "img")
fileprefix = "aug08_2010"
for Rst in LstRst:
Img1 = string.find(Rst, fileprefix + "_stanislaus.img")
if Img1 > -1:
print Rst
