# Function to display a title in uppercase, centered with extra spaces and lines above and below it
def WriteTitle(text):
    # Convert the text to uppercase
    text = text.upper()
    
    # Calculate the total width of the screen (80 characters)
    screen_width = 80
    
    # Calculate how many spaces are needed on the left and right to center the text
    spaces = (screen_width - len(text) - 2) // 2  # The extra 2 accounts for the space on both sides of the text
    
    # Create a line of hyphens based on the text length
    line = '-' * (len(text) + 2)  # The 2 extra characters account for spaces around the text
    
    # Print a line of hyphens above the text
    print(line)
    
    # Print the text centered with spaces on both sides
    print(' ' * spaces + text + ' ' * spaces)
    
    # Print a line of hyphens below the text
    print(line)

# Main function to prompt the user for a title and display it
def main():
    # Prompt the user for a title

    # Check if the title is empty
    if not title:
        # Print an error message if no title is provided
        print("Error: No title provided.")
        
        # Exit the program with an exit code of 1 to indicate an error
        sys.exit(1)
    
    # Call the WriteTitle function to display the title if valid input is provided
    WriteTitle(title)

# Run the main function if the script is executed directly
