Greetings Function: 4 Points Start With The Greeting Program ✓ Solved

Greetings Function 4 Pointsstart With The Greeting Prog

Greetings Function 4 Pointsstart With The Greeting Prog

Rewrite and implement three programming tasks involving functions, user inputs, and conditional logic in Python. The tasks include modifying a greeting function to return an uppercase name with exclamation marks, creating a quiz question function to interact with the user, and designing a system to determine if a computer meets upgrade requirements for Windows 10 based on user input. Additionally, an extra challenge involves refactoring a college ID card program into functions for better structure and reusability.

Introduction

In this comprehensive programming exercise, we explore fundamental concepts of functions, conditionals, and user interaction within Python. These tasks demonstrate practical applications such as creating engaging functions, validating user input, and managing program flow conditionally to produce dynamic outputs. The assignment also emphasizes code organization through refactoring for clarity and maintainability.

Task 1: Modified Greeting Function

The first task involves modifying an existing greeting function. The goal is to have the function accept a user's name, convert it to uppercase, and append exclamation marks. This task underscores string manipulation and function return values in Python.

Implementation Details

Function name: greeting

The function should take a string argument, representing the user's name.

The function should return a string: 'HELLO [NAME]!!!!', where [NAME] is the uppercase name provided.

Sample code snippet:

def greeting(name):


return "HELLO " + name.upper() + "!!!!"


user_name = input("Enter your name: ")


print(greeting(user_name))

Task 2: Quiz Question Function

This task entails creating a function that presents a quiz question, receives an answer from the user, and provides feedback based on correctness.

Implementation Details

  • The function, say quiz_question, takes two parameters: question and correct_answer.
  • It prints the question, prompts the user for an answer, and compares it to the correct answer.
  • If correct, prints "Correct!", otherwise displays "Incorrect. The correct answer is [correct_answer]."
  • The function does not return a value.
  • Example invocations:
quiz_question("What year did Apollo 11 land on the moon?", "1969")


quiz_question("Who painted the Mona Lisa?", "Leonardo da Vinci")

Sample code snippet:

def quiz_question(question, correct_answer):


print(question)


answer = input("Your answer: ")


if answer.strip().lower() == correct_answer.lower():


print("Correct!")


else:


print(f"Incorrect. The correct answer is {correct_answer}.")


quiz_question("What year did Apollo 11 land on the moon?", "1969")


quiz_question("Who painted the Mona Lisa?", "Leonardo da Vinci")

Task 3: Windows 10 Upgrade Eligibility

This project prompts the user for system specifications and determines whether their computer is eligible for a Windows 10 upgrade based on predefined requirements.

Implementation Details

  • The program asks for three inputs:
  • Memory in GB (e.g., 8)
  • Processor speed in GHz (e.g., 2.6)
  • Current operating system (e.g., Windows 8)
  • The function can_upgrade receives these inputs and returns True if the computer meets all the upgrade requirements, otherwise False.
  • The requirements are:
    • Memory ≥ 1 GB
    • Processor ≥ 1 GHz
    • Operating system is Windows 7 or Windows 8
  • After calling can_upgrade, the program outputs whether the user can upgrade to Windows 10.

Sample code snippet:

def can_upgrade(memory, processor_speed, current_os):


if memory >= 1 and processor_speed >= 1 and current_os in ["Windows 7", "Windows 8"]:


return True


else:


return False


def main():


mem = float(input("Enter current memory (GB): "))


proc = float(input("Enter processor speed (GHz): "))


os_name = input("Enter your current operating system: ")


if can_upgrade(mem, proc, os_name):


print("Your computer can be upgraded to Windows 10.")


else:


print("Your computer cannot be upgraded to Windows 10 based on the requirements.")


main()

Extra Credit: Refactoring the College ID Card Program

The extra challenge involves taking a non-functional or procedural program and refactoring it into well-structured functions. These might include functions for validating data, printing formatted ID cards, or adding color and style, thus improving code readability and reusability.

Such refactoring promotes modular code, making it easier to manage, update, and understand, especially as complexity grows.

Conclusion

This assignment offers a broad spectrum of fundamental programming concepts, including string manipulation, conditional logic, user input validation, and code organization. By implementing these tasks, students reinforce their understanding of Python functions and control flow, which are vital skills for software development and problem-solving.
