Lab 2

Lab Description

The program asks for two integers. Then the user is given the sum, the difference, the product and the quotient of the two integers. After the user is told whether the integers are greater than or less than the other, or if they are the same. 

Code

# This is a comment
# First Script

a_str = input(“please enter a number: “)
b_str = input(“please enter a second number: “)

a = int(a_str)
b = int(b_str)

#Processing Stage

if a==0:
print(“Program End”)

elif b==0:
print(“Program End”)

else:
my_sum = a+b
my_difference = a-b
my_product = a*b
my_quotient = a/b

#Output Stage

print(‘The sum of both numbers are:’,my_sum)

print(‘The difference of both numbers are:’,my_difference)

print(‘The product of both numbers are:’,my_product)

print(‘The quotient of both numbers are:’,my_quotient)

if a>b:
print(‘The first value is greater than the second value’,my_difference)

elif a<b:
print(‘The second value is greater than the first value’,my_difference)

else:
print(‘Both values are the same’,my_difference)

 Lab 4

Lab Description

1: (Exercise 1, Chapter 8) Write a function that takes a string as an argument and displays the letters backward, one per line.

2: (Exercise 3, Chapter 10)Write a function that takes a list of numbers and returns the cumulative sum; that is, a new list where the ith element is the sum of the first i+1 elements from the original list. For example, the cumulative sum of [1, 2, 3] is [1, 3, 6].

 Code 1 (Exercise 1)

object = ‘watch’
index = 0
while index < len(object):
letter = object[index]
print ‘\n’.join(reversed(‘watch’))
index = index + 1
