Question

Assignment 1. Console Application IN PYTHON

For this assignment you are to create a class called Lab1. Inside the class you will create three methods that will modify a three-digit whole number:

sumNums - This method takes as input a three digit int and returns the sum of the three numbers. For instance, 123 would return 6 because 3 + 2 + 1 is 6

reverseNums - This method takes as input a three digit whole number and returns the number in reverse as a String. For instance, 123 would return "321"

getList - This method takes as an argument a three digit whole number and returns the numbers as an int list. Each element of the list should contain one of the numbers

In the main method prompt for a three digit number to be input.

1. Create an instance of the Lab1 class
2. Call the sumNums method passing to it the whole number that was input into the Console window
3. Call the reverseNums method passing to it the whole number that was input into the Console window.
4. Call the getList method passing the whole number that was input at the Console window. Print the list out one number per line from the Main method using a for loop.

Note:

You can use a for loop to iterate through a list as follows:

myList = [2,4,6,8,10]

for nums in myList:
    print(nums)

Your output should be the sum of the digits, the whole number in reverse order as a String, and the int as a list.

Your output should resemble the following:

Things to Review

• for loops
• counted loops with while
• lists
• Value producing methods

Things that will cost you points

• Converting the three-digit number to a string to get each individual character. You should use modulus and divide.
• print in any method of the class
• Using input in any method of the class.

Answer 1

Have a look at the below code. I have put comments wherever required for better understanding.

class Lab1:
  # create the constructor
  def __init__(self,number):
    self.number = number 
  # create sum function
  def sumNums(self):
   # take variable to store sum
    sum = 0 

    copy = self.number
    # loop while numer is greater than 0
    while (copy>0):
      # get the last digit
      rem = copy%10 
      # divide number by 10
      copy = copy//10
      # sum the digit
      sum+=rem 
    # return sum
    return sum 

  def reverseNums(self):
    # take variable to store reverse number
    rev = ""

    copy = self.number
    # loop while numer is greater than 0
    while (copy>0):
      # get the last digit
      rem = copy%10 
      # divide number by 10
      copy = copy//10
      # add it to string variable
      rev+=str(rem)
    # return reverse
    return rev 


  def getList(self):
    # take empty list to store digits
    lst = []
    
    copy = self.number
    # loop while numer is greater than 0
    while (copy>0):
       # get the last digit
      rem = copy%10 
      # divide number by 10
      copy = copy//10
      # add it to the list
      lst.append(rem)
    # return list
    return lst[::-1] 

# take user input
number = int(input("Enter the three digit number: "))
# create object
obj = Lab1(number)
# call each method
print(obj.sumNums())
print(obj.reverseNums())
print(obj.getList())
