I am totally lost on this Python Coding assignment. It has three parts, a, b and c. I go to create A which is creating a class and needing to use a UN.txt file to create a pickled binary file named nationsDict.dat and saving the class in a file named nation.py - I get the below error with my code in the first step. Please help!

Chapter 7 Programming Projects 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). Some lines of the file are Canada, North America, 34.8,3855000 France, Europe, 66.3,211209 New Zealand, Australia/Oceania, 4.4,103738 Nigeria, Africa, 177.2,356669 Pakistan, Asia, 196.2,310403 Peru, South America, 30.1,496226 a. Create 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. Write a program that uses the class to create a dictionary of 193 items, where each item of the dictionary has the form name of a country: Natian 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.
