Hello! Looking for assistance for my Python programming project. I am having issues with part (c) . I was able to have a nationsDict.dat created with part (b), and my code seems to work fine. If you could please help assist on the explanation and coding with a screenshot with all the indentations, I would be grateful.

1. United Nations: The file UN.txt gives data about the 193 members of the United Nations. Each line of the file contains four pieces of data about a country - name, continent, population (in millions), and land area (in square miles).

(a)I need help creating a class named Nation with four instance variables to hold the data for a country and a method named popDensity that calculates the population density of the country. I need help writing a program that uses the class to create a dictionary of 193 items, where each item of the dictionary has the form

name of country: Nation object for that country

Use the file UN.txt to create the dictionary, and save the dictionary in a pickled binary file named nationsDict.dat. Also, save the class Nation in a file named nation.py

(b) I need assistance to write a program that requests the name of a U.N. member country as input, and then displays information about the country as shown in Fig 7.20. Use the pickled binary file nationsDict.dat and the file nation.py created in part (a)

(c) I need assistance write a program that requests the name of a continent as input, and then displays the names (in descending order) of the the five most densely populated U.N. member countries in that continent. See Fig 7.21. I need to use the pickled binary file nationsDict.dat and the file nation.py created in part (a).

Here is the UN.txt
