Question
Write a class CITY in Python with following specifications
Instance Attributes
-Code # Numeric value
-Name # String value
-Pop #Numeric value of population
-KM # Numeric value
-Density #Numeric value for Population Density
Methods:
CalDen()# Method to calculate Density as Pop/KM
Record()# Method to allow user to enter values
Code,Name,Pop,KM and call CalDen() method
See()# Method to display all the members also display
a message ”Highly Populated Area”
if the Density is more than 12000
Solution
class CITY: def __init__(self): self.Code = 0 self.Name = '' self.Pop = 0 self.KM =0 self.Density=0 def CalDen(self): self.Density = self.Pop / self.KM def Record(self): self.Code = input('Enter Code') self.Name = raw_input('Enter Name') self.Pop = input('Enter population') self.KM = input(“Enter KM”) CalDen(self) // or self.CalDen() def See(self): print Code,Name,Pop, KM, Density if self.Density > 12000: print('Highly Populated Area')
