<code>python3 checkA2checkA1.py -f -v TestPercent</code>

<code>python3 checkA2checkA1.py -f -v TestDuSub</code>

* 1. <code>create_dir_dict</code> will take your list from <code>call_du_sub</code> and return a dictionary. ** Every item in your list should create a key in your dictionary.** Your dictionary values should be a number of bytes.

** Again, test using your Python interpreter or the check script. To run the check script, enter the following: <code>python3 checkA2.py -f -v TestDirDict</code> You will be using a module in the standard library called <b>Argparse</b>. This will help handle more complex sets of options and arguments than simply using sys.argv.Refer to the argparse documentation to complete the <code>parse_command_args</code> function. At minimum, your assignment should handle the following options and arguments: * -h will print a usage message. This will automatically be created by argparse itself, you will not need to implement this. However, refer carefully to the sample output and ensure that your help message matches the required output.* -H will print file sizes in Human readable format. For example, 1024 bytes will be printed as 1K, 1024 kilobytes will be printed as 1M, and so on. * -l <number> will set the maximum length of the bar graph. The default should be 20 character. This option will require an option argument that is an integer.* Your script will also require one positional argument which contains the target directory for scanning. Your assignment should be able to produce the following: <code><b>user@host ~ $ python3 duim.py -h</b></code><pre>usage: duim.py [-h] [-H] [-l LENGTH] [target] DU Improved -- See Disk Usage Report with bar charts

positional arguments* To run the check script, enter the following: target The directory to scan.

optional arguments: -h, --help show this help message and exit -H, --human-readable print sizes in human readable format (e<code>python3 checkA1.g. 1K 23M 2G) py -l LENGTH, f --length LENGTH Specify the length of the graph. Default is 20.v TestDirDict</code>

Copyright 20222. <code>get_total</precode>needs to accept your dictionary, and the target directory, and return the total size in bytes of the target directory.

* Use the following to test your code:

<code>python3 checkA2checkA1.py -f -v TestArgsTestTotal</code>

* In your <code>if __name__ == '__main__'</code> block, you will have to call accept a command line argument from the parse_command_args function. Experiment with print statements so that you understand how each option and argument are storeduser This will become your target directory.

* Pass the return value from that function to <code>create_dir_dict</code>.* You may wish Pass the dictionary into <code>get_total</code> to create one or more functions to do get the total size of the target.* For each item in your dictionary (excluding the followingtarget):
