1. Setting Up Your Python File

The initial step in any programming assignment is to create a Python file that is clearly named and organized. For example, if your name is Alex Smith, a suitable name for your file might be M6Lab_String_AlexSmith.py. This naming convention is crucial as it helps keep your work organized, especially when dealing with multiple files or collaborating with peers.

At the top of your Python file, include a title comment block. This block should contain:

• A brief description of the project or the assignment’s purpose.
• The date of creation or modification.
• The course or module name associated with the assignment.
• Your full name to identify the author of the code.

Including this comment block is not just a matter of good practice but also a way to provide important context for anyone who might review or work with your code in the future. It helps in understanding the project’s objective and the author’s identity, which is especially useful in collaborative environments or when submitting assignments for evaluation.

Here’s an example of what your title comment block might look like:

# A brief description of the project

# Date: [Insert Date]

# CSC121 M6Lab – Reading String

# Alex Smith

2. Processing User Input

In this part of the assignment, you will focus on writing a program that effectively interacts with users by processing their input. This involves several key steps:

• Prompt the User: Begin by asking the user to enter a date in the format mm/dd/yyyy. Ensure that your prompt is clear, precise, and user-friendly to avoid any potential confusion.
• Process and Format the Input: Convert the entered date into a more readable format, such as Month dd, yyyy. This step makes the date easier for users to understand and interpret.

Here’s a detailed pseudocode example to illustrate this process:

1. Prompt the user to enter a date in the format mm/dd/yyyy.
2. Split the date string into three components: month, day, and year.
3. Use a predefined list of month names to convert the numeric month part into its corresponding name.
4. Format the date and print it in the format Month dd, yyyy to enhance readability and user comprehension.

Sample Code:

# Function to convert month number to month name def get_month_name(month_number): # List of month names in order months = ["January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December"] # Return the month name corresponding to the month number return months[month_number - 1] # Main function to execute the program logic def main(): # Prompt the user to enter a date date_input = input("Enter a date (mm/dd/yyyy): ") # Split the date input into month, day, and year month, day, year = map(int, date_input.split('/')) # Get the name of the month from the month number month_name = get_month_name(month) # Print the formatted date print(f"{month_name} {day}, {year}") if __name__ == "__main__": main()

3. Implementing a Menu-Driven Interface

To make your program more interactive and user-friendly, you need to implement a menu-driven interface. This interface allows users to select from various options and navigate through different functionalities seamlessly. Here’s how you can approach creating this menu:

1. Display Menu Options: Present a set of choices to the user, including:

• Option 1: Prompt the user to enter a date.
• Option 2: Exit the program.

2. Handle User Choices:

• If the user selects option 1, execute the function that processes and formats the date.
• If the user selects option 2, terminate the program and display a farewell message.
• If the user enters an invalid choice, display an error message and prompt the user to select again.

3. Loop Until Exit: Continuously display the menu and handle user choices until the user decides to exit the program.

Sample Code:

def display_menu(): # Display menu options to the user print("1. Enter a date") print("2. Exit") def main(): while True: # Display the menu to the user display_menu() # Get the user's choice choice = input("Enter your choice: ") if choice == "1": # Process the date input if choice is 1 date_input = input("Enter a date (mm/dd/yyyy): ") month, day, year = map(int, date_input.split('/')) month_name = get_month_name(month) print(f"{month_name} {day}, {year}") elif choice == "2": # Exit the program if choice is 2 print("Exiting the program. Have a great day!") break else: # Handle invalid choices print("Invalid choice. Please select a valid option from the menu.") if __name__ == "__main__": main()

4. Writing Pseudocode

Before diving into actual coding, it is vital to draft pseudocode. Pseudocode serves as a planning tool that helps you outline the logic and structure of your program. It acts as a roadmap, allowing you to organize your thoughts and ensure that all necessary components are covered. Here’s an expanded pseudocode draft for a menu-driven program:

1. Define a Function to Convert Month Number to Name:

• Create a list of month names, ordered from January to December.
• Implement a function that returns the month name based on the provided month number.

2. Define the Main Function to Manage User Interaction and Program Flow:

• Display the menu options to the user.
• Handle user input based on the selected menu choices:
• If the user selects the option to enter a date, invoke the function that processes and formats the date.
• If the user selects the option to exit, end the program and display an exit message.
• If the user inputs an invalid choice, display an error message and prompt them to choose again.
• Continuously repeat the menu display and choice handling until the user decides to exit.

By incorporating these detailed components into your approach, you will be well-prepared to tackle programming assignments that involve string manipulation and menu-driven interfaces. This structured methodology will enhance your problem-solving skills and improve the overall quality and maintainability of your code.
