How do I parse command-line colors and progress bars?

Parsing command-line colors and creating progress bars in Python can enhance the user experience of command-line applications. Below is an example of how to implement these features using the `colorama` library for coloring and a simple function to display a progress bar.

Keywords: Python, command-line colors, progress bars, colorama, user experience
Description: This example demonstrates how to parse command-line arguments for colors and display a dynamic progress bar in a Python application, improving visual feedback for users.
import sys import time from colorama import Fore, Style, init # Initialize Colorama init(autoreset=True) def print_progress_bar(iteration, total, prefix='', length=50, fill='█'): percent = (iteration / total) * 100 filled_length = int(length * iteration // total) bar = fill * filled_length + '-' * (length - filled_length) print(f'\r{prefix} |{bar}| {percent:.1f}% Complete', end='') if __name__ == '__main__': total_items = 100 for i in range(total_items + 1): time.sleep(0.1) # Simulate some work print_progress_bar(i, total_items, prefix=f"{Fore.GREEN}Loading{Style.RESET_ALL}")
