description	Python library for rich text and beautiful terminal formatting. Provides color, tables, progress bars, markdown rendering, syntax highlighting, tracebacks, logging handlers, prompts, live displays, and pretty printing. Use when building CLI applications that need styled output, displaying data in tables or trees, or enhancing debugging with improved tracebacks.

Rich 15.0.0

Overview

Rich is a Python library for rich text and beautiful formatting in the terminal. It makes it easy to add color and style to terminal output, and can render pretty tables, progress bars, markdown, syntax-highlighted source code, tracebacks, trees, columns, panels, live displays, layouts, and more — out of the box.

Rich works with Linux, macOS, and Windows (including both legacy cmd.exe and the new Windows Terminal). It requires Python 3.8 or later and works with Jupyter notebooks with no additional configuration required for basic usage.

Key capabilities:

• Styled text output via console markup (BBCode-like syntax) and programmatic styles
• Console object as the central hub for all rendering, with auto-detected terminal capabilities
• Built-in renderables: Tables, Panels, Trees, Columns, Padding, Progress bars, Syntax highlighting, Markdown, and more
• Progress tracking with track() for simple loops or full Progress class for multi-task displays
• Live display for continuously updating terminal content (dashboards, real-time data)
• Layout system for dividing the terminal screen into regions
• Pretty printing of Python data structures with syntax highlighting and indent guides
• Enhanced tracebacks with code context, local variables, and frame suppression
• Logging handler that colorizes Python's standard logging module output
• Prompt utilities for validated user input (strings, integers, floats, confirmations)

When to Use

• Building CLI applications that need visually appealing output with colors, styles, and structured layouts
• Displaying tabular data in the terminal with flexible formatting options
• Tracking progress of long-running operations (file transfers, batch processing, data pipelines)
• Rendering markdown documents or code with syntax highlighting directly in the terminal
• Enhancing debugging output with pretty-printed data structures and improved tracebacks
• Creating real-time dashboards or live-updating displays in the terminal
• Adding styled prompts for user input with validation
• Integrating rich formatting into Python's logging module

Installation / Setup

Install from PyPI:

python -m pip install rich

For Jupyter notebook support, include the extra dependencies:

python -m pip install "rich[jupyter]"

Test the installation with the built-in demo:

python -m rich

Usage Examples

Quick Start — Drop-in Print Replacement

Import Rich's print as a drop-in replacement for Python's built-in:

from rich import print

print("Hello, [bold magenta]World[/bold magenta]!", ":vampire:")
print({"name": "Alice", "score": 95})

Rich automatically pretty-prints data structures and renders console markup for styling.

Using the Console Object

For full control, create a Console instance:

from rich.console import Console

console = Console()
console.print("Hello, World!", style="bold red")
console.print("[blue underline]This looks like a link[/]")
console.print(locals())

Progress Tracking

Track any iterable with minimal code:

from rich.progress import track
import time

for i in track(range(100), description="Processing..."):
    time.sleep(0.05)

Tables

Render tabular data with flexible formatting:

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

console = Console()
table = Table(title="Movie Schedule")

table.add_column("Release", justify="right", style="cyan", no_wrap=True)
table.add_column("Title", style="magenta")
table.add_column("Box Office", justify="right", style="green")

table.add_row("Dec 20, 2019", "Star Wars: Rise of Skywalker", "$952,110,690")
table.add_row("May 25, 2018", "Solo: A Star Wars Story", "$393,151,347")

console.print(table)

Syntax Highlighting

Display code with syntax highlighting:

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

console = Console()
syntax = Syntax.from_path("example.py", theme="monokai", line_numbers=True)
console.print(syntax)
