Tail Program In Python...

This program is used to open the file specified and to print the last 10 lines of the file.

Program:


import sys


def main(): 
 line= []
 last = []
 filein = open(sys.argv[1],"r")
 for a in filein:
           line.append(a)
 last = line[-10:]
 for each in last:
           print each
main()


While running python tail.py sample_file.txt in terminal, the programs prints the last 10 lines of the file "sample_file.txt".
