Command line - Python - Create a text border with dynamic size

Creating a text border with a dynamic size in Python for command-line output can be achieved using simple string manipulation techniques. Here's a basic example of how you can create a bordered text output:

def create_bordered_text(text): lines = text.splitlines() max_length = max(len(line) for line in lines) border = '+' + '-' * (max_length + 2) + '+' result = [border] for line in lines: result.append(f'| {line.ljust(max_length)} |') result.append(border) return '\n'.join(result) # Example usage: text = """ Hello, this is some text that should be bordered. This text has multiple lines. """ bordered_text = create_bordered_text(text) print(bordered_text)

Explanation:

  1. create_bordered_text Function:

    • text.splitlines(): Splits the input text into lines.
    • max_length = max(len(line) for line in lines): Finds the maximum length of lines to determine the width of the border.
    • border = '+' + '-' * (max_length + 2) + '+': Constructs the top and bottom borders.
    • Constructs each line with left and right borders ('|') and padding (line.ljust(max_length)).

  2. Example Usage:

    • Defines text containing the content to be bordered.
    • Calls create_bordered_text(text) to generate the bordered text.
    • Prints the bordered text.

  3. Output:

    +------------------------------------+ | Hello, this is some text that should be bordered. | | This text has multiple lines. | +------------------------------------+

Notes:

  • Customization: You can customize the border style (+, -, |) and padding (ljust, rjust, center) based on your preferences.

  • Dynamic Sizing: This example dynamically adjusts the border size based on the longest line in the input text. Adjustments can be made for different border styles or additional features like centered text.

  • Enhancements: For more complex borders or special characters, consider using Unicode characters or ASCII art libraries for richer text formatting.

This approach provides a straightforward method to create a bordered text output in Python, suitable for various command-line applications where clear visual separation or formatting is required.
