Random Access

Random access is generally known as direct access. Random access is the capability to have access to any item from a given population of elements at random. Sequential access is the direct opposite of random access. In random access, the elements can be retrieved irrespective of the location. In order to move from point A to Z, you can just jump to point Z in random access system. The disk is an example of random access.

Please comment all code Using a python editor, write a python script that imports os and does the following: - it changes the directory to net312 created previously.- it displays the current directory.- it checks if the path to one of the subdirectories of net312 exists.- it checks if the name of one of the files created previously is a directory.- it returns the sizes of both files.- uses for a loop to print the content of net312 as a list of strings.- uses a for loop to retrieve all files with the extension .xlsx.- uses a for loop to join a few files to the net312.
create a Python script. Your script should: Ask the user for the name of a file (if the file exists it will be in the current directory). If the file does not exist, your script should inform the user of the error and let them try again. Allow the user to exit the program gracefully without actually processing a file - you may choose how to do this, just make sure the user knows! The program should only display the first five (5) lines of the file's content. If the file contains less than five (5) lines, it should display the file's entire content. Be sure your script can handle at least the following conditions: *The file does not exist *There are no lines in the file *There are more than five lines in the file *There are exactly five lines in the file
Answer all questions else downvote question 1. Create a script where you prompt the user for input, and the value provided will be a user. Loop through each file in that user's home directory (ignore the sub directories) and count the number of times a file contains the word ERROR (hint use 'wc' command to help with counting) and output the total number of errors at the end of the script. Once completed, take a screenshot of the source code of the script, and of the script executing, to execute the script you will need to create your own sample input, please include the sample input as part of your execution screenshot. question 2.
