Underline Text Function - Python Programming Exercise

In this exercise, you will develop a Python function that can center the text on the screen (assuming a screen width of 80 characters) and then underline it with hyphens. This exercise is perfect for practicing string manipulation and formatting in Python. By implementing this function, you will gain hands-on experience in handling string manipulation and formatting in Python. This exercise not only reinforces your understanding of string manipulation but also helps you develop efficient coding practices for managing user interactions.

Underline Text Function

 Objective

Develop a Python function that can center the text on the screen (assuming a screen width of 80 characters) and then underline it with hyphens:

write_underlined("Hello!")

 Example Python Exercise

 Copy Python Code 
# Define the function write_underlined which accepts text as a parameter
def write_underlined(text):
    screen_width = 80  # Assume the width of the screen is 80 characters
    # Calculate the padding needed on the left side to center the text
    padding_left = (screen_width - len(text)) // 2  # Calculate the number of spaces to center the text
    # Print the centered text
    print(' ' * padding_left + text)  # Print the text with leading spaces for centering
    # Print the underline below the text. Only underline the letters, not the spaces.
    underline = '-' * len(text)  # Create the underline with the same length as the text
    print(' ' * padding_left + underline)  # Print the underline with the same length as the text

# Main code to call write_underlined with the text "Hello!"
write_underlined("Hello!")  # Call the function with the text "Hello!"

 Output

                                   Hello!
                                   ------
