how to write script for these 1.Given a test file containing lines of words such as (abc, abb, abd,abb, etc), write a script that prints, in order of frequency, how many times each word appears in the file.
2. Write a script running in an endless loop that pings an IP (specified on the command line) periodically. If the IP goes down n times in a row send one email message (to an address specified on the command line) that it's down (n is specified on the command line). Once it's available again n times in a row send an email that it's back up. When a specific signal is sent to the script it sends and email saying that it is shutting down and then exits thanx satish -- http://mail.python.org/mailman/listinfo/python-list
