Rich can render text or other Rich renderables in neat columns with the Columns class. To use, construct a Columns instance with an iterable of renderables and print it to the Console.

The following example is a very basic clone of the ls command in OSX / Linux to list directory contents:

import os
import sys

from rich import print
from rich.columns import Columns

if len(sys.argv) < 2:
    print("Usage: python DIRECTORY")
    directory = os.listdir(sys.argv[1])
    columns = Columns(directory, equal=True, expand=True)

See for an example which outputs columns containing more than just text.
