Python Module: Rich

Rich is a Python library for rich text and beautiful formatting in the terminal. Use uv add rich or pip install rich to install the library.

Quick Start

from rich import print

print("[bold magenta]Hello[/bold magenta] [green]World![/green]")

Text Styles

Use style tags inside print() or use the Text class.

from rich import print
from rich.text import Text

# Inline styles
print("[bold red]Error:[/] Something went wrong!")

# Using Text object
text = Text("Important", style="bold underline green")
print(text)

Common styles:

bold, italic, underline, strike, dim
Colors: red, green, blue, yellow, etc.
Background: on red, on green

Tables

from rich.table import Table
from rich.console import Console

console = Console()
table = Table(title="User Info")

table.add_column("Name", style="cyan")
table.add_column("Role", style="magenta")
table.add_row("Alice", "Admin")
table.add_row("Bob", "User")

console.print(table)

Panels

from rich.panel import Panel

console.print(Panel("This is inside a panel", title="Note", subtitle="footer", style="bold cyan"))

Logging

Rich can enhance Python’s logging module.

import logging
from rich.logging import RichHandler

logging.basicConfig(level="INFO", handlers=[RichHandler()])
log = logging.getLogger("rich")

log.info("This is an info message")

Progress Bars

from rich.progress import Progress
import time

progress = Progress()

with progress:
    task = progress.add_task("Processing...", total=100)
    while not progress.finished:
        progress.update(task, advance=1)
        time.sleep(0.05)

Syntax Highlighting

from rich.console import Console
from rich.syntax import Syntax

code = """def hello():\n    print("Hello, World!")"""
syntax = Syntax(code, "python", theme="monokai", line_numbers=True)
console = Console()
console.print(syntax)

Layouts and Live Updates

from rich.live import Live
from rich.table import Table
import time

table = Table()
table.add_column("Time")

with Live(table, refresh_per_second=4):
    for _ in range(10):
        table.add_row(time.strftime("%H:%M:%S"))
        time.sleep(1)

Notes

Use rich.print() for styled output instead of print().
Use Console().print() for advanced features (e.g. tables, layouts).
Rich automatically detects terminal width and color support.
