Question

Assume you are the CIO of an organization with three different IT department locations with separate costs. You want a program to perform simple IT expenditure calculations. Your IT expenditure target is $35,000 per site.

Site expenditures:
Site 1 – $35,000.
Site 2 – $37,500.
Site 3 – $42,500.

Exercise 3 – Calculating Monthly Expenses Imagine you are the IT manager for Site 3 that had annual IT expenses of $42,500. Your site was above the target of $35,500 and you want to review your monthly expenses for each month of that year to determine in what months the over-expenditure occurred.

Write a python program that:

Calculates what the monthly target would be for each of the 12 months (assuming that the target is the same each month).

Assigns the monthly target value to a variable called monthly_target.

Uses a For Loop to ask for the input of monthly expenditures for 12 months (make sure your total monthly expenditures add to the $42,500 annual expense).

Compares the expense to the monthly target and uses an if statement to determine if the expense is Over, Under, or Exact to the monthly target for each entry.

Creates a three-column display showing the month and the expense entered for that month and a third column that says Over, Under, or Exact

Answer 1

Code:

yearly_target = 35000
year_expense = 45000

#calculating monthly target
monthly_target = yearly_target/12
print("Monthly Target: ",monthly_target)
monthly_expenses = []
status = []
sum = 0
#reading monthly expenses
for i in range(12):
expense = int(input('Enter expenses for month'+str(i+1)+": "))
sum = sum + expense
monthly_expenses.append(expense)
  
#comparing the expense to the monthly target
if expense >= monthly_target:
if expense > monthly_target:
status.append("Over")
else:
status.append("Exact")
else:
status.append("Under")

print("Display of monthly expenses:")
print("Month\tExpense\t\tUsage")
for i in range(12):
print(i+1,monthly_expenses[i],status[i],sep='\t\t')

#To check if monthly expenses entered matched the yearly expense
print("Sum of Expenses entered: ",sum)
if(sum==year_expense):
print("Validated")
else:
print("Not validated")

Output:

Answer 2

Here's an example Python program that meets the requirements:

# Set the annual IT expenditure target

annual_target = 35000

# Calculate the monthly target

monthly_target = annual_target / 12

# Set the monthly expenditures list

monthly_expenses = []

# Use a for loop to get the input for each month's expenditure

for month in range(1, 13):

    while True:

        try:

            expense = float(input(f"Enter the IT expenditure for month {month}: "))

            break

        except ValueError:

            print("Invalid input. Please enter a valid number.")

    monthly_expenses.append(expense)

# Print the table header

print("{:<10}{:<15}{:<10}".format("Month", "Expense", "Result"))

print("="*35)

# Use a for loop to compare each month's expenditure to the monthly target

for month, expense in enumerate(monthly_expenses, 1):

    if expense > monthly_target:

        result = "Over"

    elif expense < monthly_target:

        result = "Under"

    else:

        result = "Exact"

    # Print the month, expense, and result for each entry

    print("{:<10}${:<15.2f}{:<10}".format(month, expense, result))

This program sets the annual IT expenditure target to $35,000, calculates the monthly target, and asks the user to input the monthly expenditures for each of the 12 months. It then uses a for loop to compare each month's expenditure to the monthly target and prints a table with the month, expense, and result for each entry. The result column indicates whether the expenditure was over, under, or exact to the monthly target.
