Read file using class and global variables.

We can further modify the read by using classes and global variables in python.

import sys

import os

import string

class readfile:

def file_read(self, file):

self.file_to_read = file

self.rfile =

print self.rfile


if len(sys.argv) == 1:

r1 = readfile()



r1 = readfile()

r1.file_read(open(sys.argv[1], 'r'))
