Perform Kriging interpolatation using ArcPy

I have multiple point feature class (r001_mean, r002_mean.....012_mean) into one folder. I am trying to write a python script to perform Kriging interpolation which will loop all the point feature class and outraster will save as it name of input raster. 

Each Point feature class hold  one Z filed only (GRID_CODE)

Below is my script, what i have so far.....its giving error massage of "not defined point_num" 

 

 

import arcpy
from arcpy import env
from arcpy.sa import *
arcpy.env.overwriteOutput = True

# Check out the ArcGIS Spatial Analyst extension license
arcpy.CheckOutExtension("Spatial")

In_Point = r"D:\NPP_Test\MERRA_TEMP_2012C" #(Point feature name:r001_mean, r002_mean.....r012_mean )
Out_Raster = r"D:\NPP_Test\MERRA_TEMP_2012D"

points = arcpy.ListFeatureClasses()


zFields = "GRID_CODE"

#Kriging Veriable
cellSize = 0.05
lagSize = 0.5780481172534
majorRange = 6
partialSill = 3.304292110
nugget = 0.002701348
kRadius = RadiusFixed(20000, 1)

#Mask region of interest
mask = r"D:\Gujarta Shape file\GUJARATSTATE.shp"

for zField in zFields:
    Point = Point_Num[:3]
    kModelUniversalObj = KrigingModelUniversal("LINEARDRIFT", lagSize, majorRange, partialSill, nugget)

    OutKriging = Kriging(inPointFeatures, zField, kModelUniversalObj, cellSize, kRadius)


    #IDWMASk = ExtractByMask(outIDW, mask)
    KrigMask = ExtractByMask(OutKriging, mask)
    #Save outraster as the same name of input
    KrigMask.save("r{}.tif".format(Point_Num))
