Python File Read operations

Open and read file from within the Python program as a single string using 'read'

import sys

import os

import string

def file_read(file):

      rfile = file.read()

      print rfile

      file = file_read(open('readme.txt', 'r'))

We can also use 

Readlines - as list of strings

Readline - reads only a single line

Read file from command line

Command line arguments lists as string with ‘sys.argv’

import sys

import os

import string

def file_read(file):

      rfile = file.read()

      print rfile

                

if len(sys.argv) == 1:

   file_read(sys.stdin)

else:

   file_read(open(sys.argv[1], 'r'))
