Question

Each question needs a screenshot of the result and the code. insert appropriate amount of comments in the code. Exercise-1: Plant class. Define a class Plant that satisfies the spec below. Hints A. For this problem, provide an implementation for the Plant spec below, and test it using the example calls provided B. Although the constructor is described in the spec (and called) using the name Plant), the internal name for a class's constructor is_init__(). (There are two underscores before and to underscores after init.) C. A "zeroeth" argument self should be included with the constructor and each method. For example, the spec shows two arguments for the constructor, but__init_() should be defined using three arguments: def-init-(self, species, mass): D. Likewise, the spec shows 0 arguments for the method getSpecies(), but that doesn't count self: def getSpecies(self): return self.species E. This "zeroeth" argument self must appear first in an argument list Plant class Represents selected information about a plant. State variables A.name - String, common name for the plant B.mass Positive float, the biomass of the plant, in kilograms Constructor Plant 2 arguments: A string representing a plant's common name, and a positive float representing the plant's initial biomass. State change: A new object of type Plant is created. The state variable name is assigned the value arg1, and the state variable mass is assigned the value arg2 Return: That newly created Plant object. Methods getName No arguments. Return: String, the name for this plant

Answer 1

Exercise 1

class Plant():

    def __init__(self,species,mass):
        self.species=species
        self.biomass=mass

    def getSpecies(self):
        return self.species

    def getMass(self):
        return self.biomass

    def setMass(self,mass):
        self.biomass=mass
        
    def getName(self):
        return self.species

tree=Plant('red oak',1042)
flower=Plant('rose',2.7)
print(tree.getName())
flower.setMass(2.85)
print(flower.getMass())

Exercise 2

class Book():
    def __init__(self,title,author,year):
        self.title=title
        self.author=author
        self.year=year
    def getTitle(self):
        return self.title
    def getAuthor(self):
        return self.author
    def getYear(self):
        return self.year
    def setYear(self,year):
        self.year=year

book1=Book('War and Peace','Leo Tolstoy',1869)
print(book1.getTitle())
print(book1.getAuthor())
print(book1.getYear())
book1.setYear(1778)
print(book1.getYear())

Exercise 3

class MyCar():
    year = 0
    color = ''
    vin_number = 0

    def __init__(self, owner, make, model):
        self.owner_name = owner
        self.make = make
        self.model = model

    def setInformation(self, year, color, vin):
        MyCar.year = year
        MyCar.color = color
        MyCar.vin_number = vin

    def DescribeCar(self):
        return 'Owner: ' + self.owner_name + ', Make: ' + self.make + ', Model: ' + \
               self.model +', Year:'+ str(MyCar.year) + ", Color: " + MyCar.color + ", " + 'vin #: ' + str(MyCar.vin_number)


Altima = MyCar("vinay", "nissan", "altima")
Altima.setInformation("2007", "red", "dsd2324424244")
print(Altima.DescribeCar())
