Compatibility
Rich is compatible with Linux, OSX, and Windows. It works seamlessly with the new Windows Terminal, supporting true color and emoji. However, for the classic terminal, Rich is limited to 16 colors. Rich requires Python 3.7 or later to function properly.
Moreover, Rich works seamlessly with Jupyter notebooks, requiring no additional configuration.
Installation
Installing Rich is quick and easy. Simply use pip or your favorite PyPI package manager to install Rich:
sh
python -m pip install rich
To test the Rich output on your terminal, run the following command:
sh
python -m rich
Using Rich
Rich provides various ways to enhance your terminal output. Here are some examples:
Rich Print
The Rich print method allows you to effortlessly add rich output to your application. Import the print method from Rich and use it with the same signature as the builtin Python function. For example:
“`python
from rich import print
print(“Hello, [bold magenta]World[/bold magenta]!”, “:vampire:”, locals())
“`
Rich REPL
Rich can be installed in the Python REPL, providing pretty printed and highlighted data structures. Simply import the pretty module from Rich and install it in the REPL:
“`python
from rich import pretty
pretty.install()
“`
Using the Console
For more control over rich terminal content, import and construct a Console object from Rich. The Console object allows you to print rich text with customizable styles and formatting. Here’s an example:
“`python
from rich.console import Console
console = Console()
console.print(“Hello”, “World!”)
“`
You can add color and style to your output by using the style keyword argument:
python
console.print("Hello", "World!", style="bold red")
The output will be something like the following:
