inode number in windows XP

[asit]

why this program shows ambiguous behavior ??

import os
import stat
import time
#import types

file_name=raw_input("Enter file name : ")
print file_name, "information"
st=os.stat(file_name)
print "mode", "=>", oct(stat.S_IMODE(st[stat.ST_MODE]))

print "type","=>",
if stat.S_ISDIR(st[stat.ST_MODE]):
    print "DIReCTORY"
elif stat.S_ISREG(st[stat.ST_MODE]):
    print "REGULAR"
elif stat.S_ISLINK(st[stat.ST_MODE]):
    print "LINK"

print "file size", "=>",st[stat.ST_SIZE]
print "inode number", "=>",st[stat.ST_INO]
print "device inode resides on", "=>",st[stat.ST_DEV]
print "number of links to this inode", "=>",st[stat.ST_NLINK]
print "last accessed", "=>", time.ctime(st[stat.ST_ATIME])
print "last modified", "=>", time.ctime(st[stat.ST_MTIME])
print "inode changed", "=>", time.ctime(st[stat.ST_CTIME])



i ran this program in Winows XP SP2 in python 2.5.
