Question

python3

d. Make a class called "bad_math' that has 2 variables, a and b. Include all the necessary functions, but also write a function called bad_addition' that adds the e. Using the above class, write code that creates a new "bad_math' object, sets a and b to 5 and 12, and then calls 'bad addition' on the object. f. Write code that asks for number input from the user until they type in a 0, then prints out the sum of the numbers typed in.

Answer 1

d.

import random   

class bad_math:

def __init__(self,a,b):
self.a=a
self.b=b

def seta(self,a):
self.a=a

def geta(self):
return a

def setb(self,b):
self.b=b

def getb(self):
return b

def bad_addition(self):
add = self.a + self.b   
add = add - random.random()
print("a + b - random number = " + str(add))

e.

b = bad_math(5,12)
b.bad_addition()

=======================================================================================

complete program for question d and e:

import random # import random, to generate random numbers

class bad_math: # class bad_math

def __init__(self,a,b): # constructor. takes values of a and b as parameter and assigns to the class variables
self.a=a
self.b=b

def seta(self,a): # Mutators and accessord for variables a and b
self.a=a

def geta(self):
return a

def setb(self,b):
self.b=b

def getb(self):
return b

def bad_addition(self): # bad_addition()
add = self.a + self.b # adds a and b and stores the added number in add variable
add = add - random.random() # generate a random number and subtract from add
print("a + b - random number = " + str(add)) # print the result

b = bad_math(5,12) # create object of bad_math b
b.bad_addition() # call bad_addition()

Output:

a + b - random number = 16.310302828677873

Screenshot of the code:

import random # import random, to generate random numbers class bad_math: # class bad_math # constructor. takes values of a and b as parameter and assigns to the class variables def __init__(self, a,b): self.a=a self.b=b def seta (self, a) : self.a=a # Mutators and accessord for variables a and b def geta (self): return a def setb (self,b): self.b=b def getb(self): return b def bad_addition (self): add = self.a + self.b add = add - random.random() print ("a + b - random number = " + str(add)) # bad addition) # adds a and b and stores the added number in add variable # generate a random number and subtract from add # print the result b = bad_math(5,12) b.bad_addition() # create object of bad_math b # call bad_addition()

f.

Please find the code below:

addition = 0 # declare variable addition to 0
while True: # create an infinite loop

num = input("Please enter a number: ") # Ask user to enter a number
addition = addition + int(num) # add the number to addition

if num=='0': # if the number is 0, come out of the loop
break

print("The sum of numbers is: " + str(addition)) # print the sum (value of addition variable)

Output:

Please enter a number: 5 Please enter a number: 6 Please enter a number: 7 Please enter a number: 4 Please enter a number: 10 Please enter a number: 9 Please enter a number: 0 The sum of numbers is: 41

Screenshot of the code:

addition = 0 while True: # declare variable addition to o # create an infinite loop num = input ("Please enter a number: ") addition = addition + int (num) # Ask user to enter a number # add the number to addition # if the number is o, come out of the loop if num=='0': break print ("The sum of numbers is: " + str (addition)) # print the sum (value of addition variable)
