Getting Started with Rich

Getting started with Rich is straightforward. Simply install the library using pip, import it into your Python script or application, and start enhancing your terminal output. Here’s a quick example to get you started:

“`python
from rich import print

print(“Hello, [bold magenta]World[/bold magenta]!”, “:vampire:”, locals())
“`

This code will display “Hello, World!” in bold magenta, along with a vampire emoji. In addition, Rich provides many other functions and classes to help you format and style your terminal output.

Compatibility and Installation

Rich is compatible with Linux, macOS, and Windows terminals. It works with the new Windows Terminal, providing true color and emoji support. Rich requires Python 3.7 or later. To install Rich, you can use pip or any PyPI package manager. Run the following command:

sh
python -m pip install rich

Taking Control with the Console

For those seeking more control over their terminal output, Rich provides the Console class. It allows you to create sophisticated and customized terminal content. Here’s an example:

“`python
from rich.console import Console

console = Console()
console.print(“Hello”, “World!”)
“`

With the Console class, you can apply styles, word-wrap your text, and create multi-line output that adapts to the terminal width.
