Question

Question 3
The City class has the following attributes: name, country (where the city is located), elevation (measured in meters), and population (approximate, according to recent statistics). Fill in the blanks of the max_elevation_city function to return the name of the city and its country (separated by a comma), when comparing the 3 defined instances for a specified minimal population. For example, calling the function for a minimum population of 1 million: max_elevation_city(1000000) should return "Sofia, Bulgaria".
# define a basic city class
class City:
name = ""
country = ""
elevation = 0

# create a new instance of the City class and

Answer 2

Corrected program is given below.

Explanation:

The mistake in your program was Indentation. You have not given proper spacing in the program. I have corrected the program.

# define a basic city class

class City:

name = ""

country = ""

elevation = 0

population = 0

# create a new instance of the City class and

# define each attribute

city1 = City()

city1.name = "Cusco"

city1.country = "Peru"

city1.elevation = 3399

city1.population = 358052

# create a new instance of the City class and

# define each attribute

city2 = City()

city2.name = "Sofia"

city2.country = "Bulgaria"

city2.elevation = 2290

city2.population = 1241675

# create a new instance of the City class and

# define each attribute

city3 = City()

city3.name = "Seoul"

city3.country = "South Korea"

city3.elevation = 38

city3.population = 9733509

def max_elevation_city(min_population):

# Initialize the variable that will hold

# the information of the city with

# the highest elevation

 highest_elevation=0

 return_city =""

# Evaluate the 1st instance to meet the requirements:

# does city #1 have at least min_population and

# is its elevation the highest evaluated so far?

 if (city1.population>min_population):

     if(highest_elevation<city1.elevation):

         highest_elevation=city1.elevation

         return_city = ("{}, {}".format(city1.name,city1.country))

# Evaluate the 2nd instance to meet the requirements:

# does city #2 have at least min_population and

# is its elevation the highest evaluated so far?

 if(city2.population>min_population):

     if (highest_elevation<city2.elevation):

         highest_elevation=city2.elevation

         return_city = ("{}, {}".format(city2.name,city2.country))

# Evaluate the 3rd instance to meet the requirements:

# does city #3 have at least min_population and

# is its elevation the highest evaluated so far?

 if(city3.population>min_population):

     if (highest_elevation<city3.elevation):

         highest_elevation=city3.elevation

         return_city = ("{}, {}".format(city3.name,city3.country))

#Format the return string

 if return_city!="":

     return return_city

 else:

     return ""

print(max_elevation_city(100000)) # Should print "Cusco, Peru"

print(max_elevation_city(1000000)) # Should print "Sofia, Bulgaria"
