In python. Please do not copy elsewhere as it is all incorrect, and include docstring so that I can understand the information so I can apply the methods to future problems. Thanks. import the **json** module.Write a class named SatData that reads a [JSON file containing data on 2010 SAT results for New York City](https://data.cityofnewyork.us/api/views/zt9s-n5aj/rows.json?accessType=DOWNLOAD) and writes the data to a text file in CSV format. That same JSON file will be provided as a local file in Gradescope named **sat.json**. Your code does not need to access the internet.CSV is a very simple format - just commas separating columns and newlines separating rows (see note below about commas that are part of field names). You'll see an example of CSV format below. There is a csv module for Python, but you will not use it for this project.Your class should have:* an init method that reads the file and stores it in whatever data member(s) you prefer. Any data members of the SatData class…
Suppose Alice has r and w rights over the file book. Alice wants to copy r rights to book to Bob. Assuming there is a copy right c, write a command to do this. Now assume the system supports a copy flag; for example, the right r with the copy flag would be written as rc. In this case, write a command to do the copy. In the previous part, what happens if the copy flag is not copied?
A disk drive has 256 cylinders, with the numberThe cylinder starts at 0 and ends at 255. The position of the needle on the disk drive is currently stoppedat point 128. It is also known that the needle is always "to the cylinder with more numbers"Small first." The order of the positions visited in sequence is:254, 64, 32, 100, 50, 70.

in fedora 37 1. Create a directory named Module9 and navigate to that directory. 2. Copy the file pay.dat from Module8 to Module9. Here it is again, just in case: 0001:John Smith:15.40 0002:Jane Smith:15.41 0003:George Jungle:12.10 0004:Ursula Jungle:16.11 3. Using a pipe symbol for filtering and sort the data to stdout. Enter: cat pay.dat | sort 4. Now, on your own, using a pipe symbol for filtering and sort the data in descending order to stdout and append that to a file named SortPay.dat. 5. Copy pay.dat to three files named: pay10,dat, pay12.dat, and pay02.txt. You may need to use multiple commands. 6. Use pattern matching to locate only pay02.txt. 7. Enter the command to remove pay2.dat and redirect both stdin and stdout to a file named RemovePay.txt. 8. Run the command in step 7 again. 9. Display the contents of RemovePay.txt 10. Take screen captures please explain each step and take screenshots
