Introduction

In this exercise, we will create a simple Python application that performs some calculations and involves simple conditional statements. For some reason (or to make things a little simpler), we will use Microsoft Visual Studio, which is freely available, but if you want, you can use any tool you judge necessary. In fact, you can create the following application directly on the console or terminal.

ApplicationPractical Learning: Creating the Application

  1. Start Microsoft Visual Studio
  2. In the Visual Studio 2022 dialog box, click Create a New Project
  3. In the Create a New Project dialog box, in the Languages combo box, select Python
  4. In the list of projects templates, click Python Application (it should be selected already).
    Click Next
  5. Specify the Project Name as PayrollEvaluation1
  6. Click Create
  7. Change the code as follows: 
    print("Payroll Evaluation")
print("==================================================")
print("Enter the following pieces of information")
print("--------------------------------------------------")
print("Employee Information")
firstName        = input("First Name:     ")
lastName         = input("Last Name:      ")
hSalary          = float(input("Hourly Salary:  "))
print("==================================================")
print("Time worked")
print("--------------------------------------------------")
monday       = float(input("Monday:         "))
tuesday      = float(input("Tuesday:        "))
wednesday    = float(input("Wednesday:      "))
thursday     = float(input("Thursday:       "))
friday       = float(input("Friday:         "))

timeWorked   = monday + tuesday + wednesday + thursday + friday
    
regTime      = timeWorked
overTime     = 0.00
regPay       = hSalary * timeWorked
overPay      = 0.00

if timeWorked > 40.00:
    regTime  = 40.00
    overTime = timeWorked - 40.00
    regPay   = hSalary * 40.00
    overPay  = hSalary * 1.50  * overTime

netPay       = regPay + overPay

print("==================================================")
print("Payroll Evaluation")
print("==================================================")
print("Employee Information")
print("--------------------------------------------------")
print(f"Full Name:      {firstName} {lastName}")
print(f"Hourly Salary:  {hSalary:5.2f}")
print("==================================================")
print("Time Worked Summary")
print('--------+---------+-----------+----------+--------')
print(" Monday | Tuesday | Wednesday | Thursday | Friday")
print('--------+---------+-----------+----------+--------')
print(f"{monday:6.2f}  |{tuesday:6.2f}   |{wednesday:7.2f}    |{thursday:7.2f}   |{friday:6.2f}")
print("========+=========+===========+==========+========")
print("\t\t\t\tPay Summary")
print("--------------------------------------------------")
print("\t\t\t\tTime      Pay")
print("--------------------------------------------------")
print(f"\t\tRegular:\t{regTime:4.2f}\t{regPay:8.2f}")
print("--------------------------------------------------")
print(f"\t\tOver Time:\t{overTime:5.2f}\t{overPay:8.2f}")
print(f"-------------------------------------------------")
print(f"\t\tNet Pay:\t{netPay:16.2f}")
print("==================================================")
  8. To execute the project, on the main menu, click Debug and click Start Without Debugging
  9. When requested, type the values like in the first example of the previous section and press Enter each time:

Using an Opposite Conditional Statement

In the previous code, we used the Greater Than (>) operator. As it happens, its opposite if the Less Than Or Equal (<=) operator. We are going to test it.

Practical LearningPractical Learning: Using a Different Conditional Statement

  1. Change the document as follows: 
    print("Payroll Evaluation")
print("==================================================")
print("Enter the following pieces of information")
print("--------------------------------------------------")
print("Employee Information")
firstName        = input("First Name:     ")
lastName         = input("Last Name:      ")
hSalary          = float(input("Hourly Salary:  "))
print("==================================================")
print("Time worked")
print("--------------------------------------------------")
monday       = float(input("Monday:         "))
tuesday      = float(input("Tuesday:        "))
wednesday    = float(input("Wednesday:      "))
thursday     = float(input("Thursday:       "))
friday       = float(input("Friday:         "))

timeWorked   = monday + tuesday + wednesday + thursday + friday
    
regTime      = 40.00
overTime     = timeWorked - 40.00
regPay       = hSalary * 40.00
overPay      = hSalary * 1.50  * overTime

if timeWorked <= 40.00:
    regTime  = timeWorked
    overTime = 0.00
    regPay   = hSalary * timeWorked
    overPay  = 0.00

netPay       = regPay + overPay

print("==================================================")
print("Payroll Evaluation")
