I have two functions 1. First one will crated the feature layer 2. second one will access the same created layer and prints the result. but when i run my script first time it will print the wrong results. when i run it second time it will shows correct result... Correct Result: 1. layer which is creating contains only 5 Rows so my script is supposed to print only 5 messages getting access to map layer 1 getting access to map layer 2 getting access to map layer 3 getting access to map layer 4 getting access to map layer 5 Wrong Result Script running 1st Time: getting access to map layer 2 getting access to map layer 2 getting access to map layer 2 getting access to map layer 2 getting access to map layer 2 getting access to map layer 2 getting access to map layer 2 getting access to map layer 2 getting access to map layer 2 getting access to map layer 2 getting access to map layer 2 getting access to map layer 2 getting access to map layer 2 getting access to map layer 3 getting access to map layer 3 getting access to map layer 3 getting access to map layer 3 getting access to map layer 3 getting access to map layer 3 getting access to map layer 3 getting access to map layer 3 getting access to map layer 3 getting access to map layer 3 getting access to map layer 3 getting access to map layer 3 getting access to map layer 3 getting access to map layer 3 getting access to map layer 3 getting access to map layer 3 getting access to map layer 3 getting access to map layer 3 getting access to map layer 3 getting access to map layer 3 getting access to map layer 3 getting access to map layer 3 getting access to map layer 3 getting access to map layer 3 getting access to map layer 3 getting access to map layer 3 getting access to map layer 3 getting access to map layer 3 getting access to map layer 3 getting access to map layer 3 getting access to map layer 3 getting access to map layer 3 getting access to map layer 3 getting access to map layer 3 getting access to map layer 3 getting access to map layer 3 getting access to map layer 3 getting access to map layer 3 getting access to map layer 3 getting access to map layer 3 getting access to map layer 3 getting access to map layer 3 getting access to map layer 3 getting access to map layer 3 getting access to map layer 3 getting access to map layer 3 getting access to map layer 3 getting access to map layer 3 getting access to map layer 3 getting access to map layer 3 getting access to map layer 3 getting access to map layer 3 getting access to map layer 3 getting access to map layer 3 getting access to map layer 3 getting access to map layer 3 getting access to map layer 3 getting access to map layer 3 . . . . . . # import system modules import arcpy import math import sys  import traceback  from arcpy import env # Class to Build Boundry of Districts class Build_Boundry:     def __init__(self, workSpace,mapLayerFinal,censusLayer,totalDistricts,mxdLocation):       self.workSpace = workSpace       self.censusLayer = censusLayer       self.mapLayerFinal = mapLayerFinal       self.totalDistricts = totalDistricts       self.mxdLocation = mxdLocation    # Function to Calculate Average of Total Voters in each District     def boundry(self):         arcpy.AddMessage("Building Boundry of Districts ")         if arcpy.Exists(self.mapLayerFinal):             arcpy.AddMessage("Layer Already Exist.....")             print(self.mapLayerFinal)         else:             arcpy.MakeFeatureLayer_management(self.censusLayer, self.mapLayerFinal,"DISTRICT_ID BETWEEN 1 AND "+str(self.totalDistricts),self.workSpace)                          # Execute Dissolve using LANDUSE and TAXCODE as Dissolve Fields             arcpy.Dissolve_management(self.mapLayerFinal, str(self.workSpace)+"/"+str(self.mapLayerFinal), "DISTRICT_ID", "","MULTI_PART", "DISSOLVE_LINES")             print(self.mapLayerFinal)             arcpy.AddMessage("Boundry of Districts Calculated")             mxd = arcpy.mapping.MapDocument(self.mxdLocation)             df = arcpy.mapping.ListDataFrames(mxd, "")[0]             addLayer = arcpy.mapping.Layer(self.mapLayerFinal)             arcpy.mapping.AddLayer(df, addLayer,"BOTTOM")             mxd.save()             arcpy.RefreshTOC()             del mxd, addLayer                 return;
