Python Code Issue: I am trying to perform step A for this question and keep getting this error. Can you review my code and tell me what I am doing wrong?

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 countryname, continent, population (in millions), and land area (in square miles).

1. 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: 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.

class Nation: def __init__(self, country="", continent="", population=0.0, area=0): self._country = country self._continent = continent self._population = population self._area = area self._popDensity = (1000000 * float(self._population)) / int(self._area)

def setCountry(self, country): self._country = country

def setContinent(self, continent): self._continent = continent

def setPopulation(self, population): self._population = population

def setArea(self, area): self._area = area

def getCountry(self): return self._country

def getContinent(self): return self._continent

def getPopulation(self): return self._population

def getArea(self): return self._area

def popDensity(self): self._popDensity = (1000000 * self._population) / self._area return self._popDensity
