Please use Python.

Problem 6 (5 pts) Write a python script that will create the following directory structure in the local folder: folders A, B, C and D, and each of these folders have subfolders 1, 2, and 3 inside of them. Within each of the numbered folders, create a file called "readme.txt" that contains the text "This file is in folder [sep] ," where is A, B, C or D, is 1, 2, or 3, and [sep] is the appropriate directory separator for whatever platform the script is being run on. You will need to use the os module and some nested for loops. Use the write function to create the .txt files and make sure to use the format method for strings
