Create an application that allows you to keep a digital diary. A diary is composed of entries, where each entry corresponds to the information you wanted to write during a day. Your application should handle multiple diaries as multiple people can use your application and each of these people has a different diary; each of these diaries should be stored in memory in a file. The program should display an initial menu where it asks the user what they want to do$.$ The options are:

Create a diary.

Open a diary.

a$.$ Read the entire diary.

b$.$ Read the entry for a specific day.

c$.$ Add an entry to the diary.

Exit.

At the beginning, there may already be diaries that the application should be aware of; all existing diaries will be in a folder called "diaries" located in the same place as your Python $(.$py$)$ file. From your code, you should obtain this location using the os library. At the end of the program, you should write each of the diaries created by each user into this folder, with the file name being the name of the diary owner.
