=Assignment 1 - Usage Report=
'''Weight:''' 15% of the overall grade
In this assignment, your task is to create a python program to produce daily, weekly, and monthly usage reports by user or by remote host based on the information obtained from the 'last' command or given files which contain similar information as the 'last' command.
== Resource for useful modules ==
* the <b>argparse</b> module
** [https://docs.python.org/3/howto/argparse.html Argparse Tutorial] - should read this first.
** [https://docs.python.org/3/library/argparse.html Argparse API reference information page]
* the <b>time</b> module

** [https://docs.python.org/3/library/time.html Time module API reference page]
== Instructions ==
=== Program Name and valid command line arguments ===
Name your Python3 program as <code>usage_reportur.py</code>. The program should accept zero one or more "file name" as its command line parametersand other optional parameters as shown below. for examplesYour ur.py script should produce the following usage when run with the --help option:* <b><codepre>[rchan@centos7 a1]$ python3 usage_report./ur.py</code></b>, or-h* <b><code>python3 usage_reportusage: ur.py filename</code></b>[-h] [-l {user,host}] [-r RHOST] [-t {daily,weekly, ormonthly}] [-u USER] [-v]* <b><code>python3 usage_report.py filename1 filename2 </code></b> etc F [F ... ] Usage Report based on the last command positional arguments: F list of files to be processed optional arguments: -h, --help show this help message and exit -l {user,host}, --list {user,host} generate user name or remote host IP from the given files -r RHOST, --rhost RHOST usage report for the given remote host IP -t {daily,weekly,monthly}, -- any number type {daily,weekly,monthly} type of file names from 1 to as many as report: daily, weekly, and monthly -u USER, --user USER usage report for the commandgiven user name -v, --verbose tune on output verbosity Copyright 2018 -Raymond Chan </pre>Replace the last line supports.with your own full name
If there one of the file name given is no command line argument"last", your python program should get the login records from the 'last' command with the appropriate flags.
If there is one file name provided at the command line, read the login records from the contents of the given file. The format of each line in the file should be the same as the output of 'last -Fiw'.
