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.

In Python, unlike tet files, data in pickeled binary files can be randmly accessed   true or false?

In c++, ask the user for the name of a file to store the information. Open the file, and make sure it openedcorrectly.Allow the user to process multiple records. Prompt the user at the end of each cycle whether theywant to process any more records. (Hint: what kind of a loop will you use that processes at least oneitem?)Then, for each item in the inventory, your program should:1. Ask the user for the product name (use getline so you can input a multi-word product name)then read it in.2. Ask the user for the wholesale price per item and read that in.3. Ask the user for the quantity and read that in.4. Calculate the total price paid.5. Ask the user for the markup and read that in. (“Markup is usually expressed as a percentage,and is the amount the price is raised to give a retail price).6. Calculate the retail price.That forms a “record”; all the information we know about this item.Write the information to a file.The function should print to the file, on two lines, the information in the…
