Question

11) What ten values would be printed if the following code was run?

write your answer in the correct order 11a to 11j

class Pat():
def__init__(self, name, age):
self._name = name
self._age = age
def __str__(self):
return "Pet: +self._name+ " "+str(self._age)
def getName(self):
return self._name
def getAge(self):
return self._age
def setName(self,newName):
self._age =newAge
def incrementAge(self):
self._age = self._age +1

pet1 = Pet ("Fluffy" ,5)
pet2 = Pet ("Spot", 2)
print (pet1)
print (Pet.__doc__)
pet2.setName("Dot")
print(pet2.getAge())
pet1.incrementAge()
print(pet1.getAge())
pet2.setAge(4)
print(Pet.getName.__doc__)

f = open("test.dat","w")
f.write("Winter\nis almost\nover at\nlast !\n")
f.close()
f = open("test.dat" ,"r")
string = f.readline()
str1 = string.strip()
print(srt1)
string =f. readline()
str2 = string.strip()
print(str2)
str3 = str1 +" "+f.read(3)
print (str3)
string = f.readline()
str4 = string.strip()
print(str4)
f.read(1)
string = f.readline()
str4 = string.strip()
print(str4.upper())

# do comment if any problem arises

# Code has been corrected and explained in comments

class Pet():

    def __init__(self, name, age):

        self._name = name

        self._age = age

    def __str__(self):

        return "Pet: "+self._name + " " + str(self._age)

    def getName(self):

        return self._name

    def getAge(self):

        return self._age

    def setName(self, newName):

        self._name = newName

    def setAge(self, newage):

        self._age = newage

    def incrementAge(self):

        self._age = self._age + 1

pet1 = Pet("Fluffy", 5)

pet2 = Pet("Spot", 2)

# prints Fluffy 5

print(pet1)

# prints None as no docstring is set

print(Pet.__doc__)

pet2.setName("Dot")

# prints 2 age of pet2

print(pet2.getAge())

pet1.incrementAge()

# prints 6 age of pet1

print(pet1.getAge())

pet2.setAge(4)

# prints None as no docstring is set

print(Pet.getName.__doc__)

f = open("test.dat", "w")

f.write("Winter\nis almost\nover at\nlast !\n")

f.close()

f = open("test.dat", "r")

string = f.readline()

str1 = string.strip()

# prints Winter first line of test.dat

print(str1)

string = f. readline()

str2 = string.strip()

# prints is almost second line of test.dat

print(str2)

str3 = str1 + " "+f.read(3)

# prints Winter ove

print(str3)

string = f.readline()

str4 = string.strip()

# prints r at

print(str4)

f.read(1)

string = f.readline()

str4 = string.strip()

# prints AST !

print(str4.upper())
