Part 3

It is time to submit the final version of this script. Remember to review your feedback from your instructor. Take this opportunity to revise your draft script and review the applicable resources related to developing it. Great Students,
Greetings to everyone.
Welcome to Module 5.
Last week, we studied Lists and Dictionaries.
This week, we shall work on “Functions”.
Functions make it easier for us to re-use codes.
Let’s us do a simple arithmetic operation.
Let us look at this simple code (you can test this code in any Python IDE):
#Function
#We define the function
#We write the code that describes the function
#We call the function anytime we want. This saves us time.
def add(c, d):
print(c + d)
def subtract(c, d):
print(c – d)
def multiply(c, d):
print(c * d)
def divide(c, d):
print(c / d)
c = int(input(“Enter the first number”))
d = int(input(“Enter the second number”))
add(c, d)
subtract(c, d)
multiply(c, d)
divide(c, d)
Please go ahead and run the code in the Visual Studio Code IDE.
This is a simple example.
Did you notice the steps? I just did what I wrote in the comments.
Please:
Read and Study Chapter 5 of your textbook.

IT 140 Final Project Script Three Draft Guidelines and Rubric ATM Script
Overview: For your final project, you will be creating four small scripts. Collectively, the four scripts will demonstrate your ability to engage in the fundamental
scripting and problem-solving approaches that are represented by the course outcomes.
Reminder: This is the first draft. Even if your script is not functioning perfectly, submit your draft and get feedback so that you can improve on it for the final
submission in Module Seven.
Prompt: A function is a named series of statements. Invoking a function’s name, known as a function call, causes the function’s statements to execute. Python
comes with a number of built-in functions, such as input(), int(), type(), and others. A programmer can also create a new function using the def keyword, the new
function’s name, and a block of statements. A block is a series of indented statements following the function definition.
To call a function, use the function’s name followed by braces function_name(). This causes execution to jump to the function’s statements. The function’s return
causes execution to jump back to where the original call occurred, to the next statement after the call. A good practice is to follow the convention of naming
functions with lowercase letters and underscores, such as print_names or print_face.
Your task for this project is to create a simple ATM script. The script emphasizes the importance of using functions in the creation of more organized and reusable
code.
You will be working in the Project Three: ATM Script module in Codio. Following the directions in that module, you will also determine the exact placement of the
comments you will need to make in the code. Follow the directions in the module in Codio to walk through the activity. In the Codio activity you will work on
having your script do the following three things:
1. Collect customer input
2. Calculate the ending balance
3. Display the results to the customer
After completing the activity, annotate the code. Specifically, your submission of the ATM script should address the following critical elements:
I.
In Your Script (Annotated Text File)
Refer to the directions in the module in Codio for how to export out and comment your completed script.
A. Create examples of custom functions in your script.
B. Create examples of input (parameters) that are utilized within the function(s) in your script.
C. Create examples of functions that return the correct output in your script.
Rubric
Guidelines for Submission: This is a draft of part of the final project. Complete the steps in Codio, then export and comment on the completed script. Once
completed, submit the document with your commented code to Brightspace. Feedback will be provided by your instructor to incorporate in the final submission
and the reflection document.

IT 140 Final Project Script One Guidelines and Rubric
Overview
Apple cofounder Steve Jobs once said “I think everybody in this country should learn how to program a computer because it teaches you how to think.” Regardless of
your future career path, the programming concepts and the computational thinking practices gained while learning to script will prove useful. In this course, you will
have the opportunity to explore some of the introductory types of scripting and computational thinking that information technology professionals engage in when
they design solutions to social and business problems.
Programming is a both a scientific and creative undertaking. The fundamentals you learn in this course will provide the scientific foundation. Armed with these skills,
you will have the ability to expand the scientific elements to more advanced concepts that can help you solve everyday problems using tools in creative ways.
For your final project, you will be creating four small scripts. For each script assignment, you will also write a small reflective essay (one to two paragraphs in a
Microsoft Word document) in which you will discuss the problem-solving approaches and relevance of the programming concepts used in the script. Collectively, all
four small scripts and reflective essays will demonstrate your ability to engage in the fundamental scripting and problem-solving approaches that are represented by
the course outcomes:

IT-140-03: Utilize functions for producing organized, reusable code [BS.ITE.CORE.01]
IT-140-04: Write accurate regular expressions that search for specific patterns in text material [BS.ITE.CORE.01]
IT-140-05: Explain problem solving approaches required for implementing and troubleshooting scripting tasks [BS.ITE.CORE.01]
You will have an opportunity to submit a practice draft of each script early in the course and receive feedback from your instructor before you finalize the script and
submit the final version and reflection in a later module. Take advantage of these practice opportunities! Even if your script is not functioning perfectly, submit your
draft and get feedback so that you can improve on it for the final submission. Follow the directions in the practice modules in Codio.

Script One: Rental Car Billing Script
Prompt
For this script, you will be using variables and branches. A variable is used to remember a value for later use. The statement “age = 15” defines a variable named age,
which Python uses to refer to a new object with the integer value 15. When a statement executes that assigns a value to an existing variable, Python updates the
variable to refer to the newly assigned object. Likewise, reading a variable’s value reads the value of the object referred to by the variable. So, in Python, if you set a
variable to a string, the variable is now a type string object.
To write useful programs, we almost always need the ability to check conditions and change the behavior of the program accordingly. Conditional statements give us
this ability. The simplest form is the if statement. A programmer commonly requires more than one if statement in branches, in which case the elif (short for “else if”)
keyword or else keyword can be used.
Your task for Final Project Script One is to create a simple rental car billing calculator. This script also emphasizes the importance of using and modifying variables,
and how branches may impact your approach in creating a script.
