{"id":1902,"library":"ansicolors","title":"ANSI colors for Python","description":"The `ansicolors` library provides a simple way to add ANSI escape codes for foreground, background, and text styles to strings for terminal output. It supports 8-color, 256-color (xterm), and 24-bit RGB color definitions. The current version is 1.1.8, released in June 2017, and the project appears to be in maintenance mode due to lack of recent updates.","status":"maintenance","version":"1.1.8","language":"en","source_language":"en","source_url":"http://github.com/jonathaneunice/colors/","tags":["console","terminal","ansi","colors","style","legacy"],"install":[{"cmd":"pip install ansicolors","lang":"bash","label":"Install with pip"}],"dependencies":[],"imports":[{"note":"The PyPI package name is 'ansicolors', but the main module to import is 'colors'.","wrong":"import ansicolors","symbol":"color","correct":"from colors import color"}],"quickstart":{"code":"from colors import color\nimport os\n\n# Basic 8-color\nprint(color('Hello, ANSI!', fg='green'))\nprint(color('Warning!', fg='black', bg='yellow', style='bold'))\n\n# Check for color support (common practice)\nif os.environ.get('NO_COLOR') is None and os.stdout.isatty():\n    # 256-color (xterm) example\n    print(\"\\n256-color palette (if supported):\")\n    for i in range(256):\n        if i % 16 == 0:\n            print()\n        print(color(f'{i:03d}', fg=i), end=' ')\n    print('\\n')\n\n    # 24-bit RGB example\n    print(color('True Color!', fg=(255, 100, 50), style='underline'))\n    print(color('Deep Blue Background', bg='#00008b', fg='white'))\nelse:\n    print(\"\\nTerminal does not support ANSI colors or NO_COLOR is set.\")","lang":"python","description":"Demonstrates basic 8-color, 256-color, and 24-bit RGB usage with foreground, background, and style options.
