All python developers will be using the console to print out messages or debug info at times in their development and some of these consoles can be running continuously, with many messages.
Being able to format and color highlight these is a NICE way to improve our scripts and to highlight specific messages which is easily done with the "Rich" library.
Rich allows you to use rich text formatting in the terminal and its super easy to use!
pip install rich
You can simply import the print function from the rich library and print will now be color syntax highlighting automatically for you with all its other features. It still uses the same inputs as the built in print, so its compatible with anything you already have written.
from rich import print
Color Syntax Highlighting
If you then print an object or data element, rich colors things nicely for you.
Justification
from rich.console import Console
console = Console(width=20)
style = "bold white on blue"
console.print("Rich", style=style)
console.print("Rich", style=style, justify="left")
console.print("Rich", style=style, justify="center")
console.print("Rich", style=style, justify="right")
This produces the following output:
Rich
Rich
Rich
Rich
Creating progress bars
from rich.progress import track
for num in track(range(100)):
print(num * 2)
time.sleep(0.1)
More Examples:
Table Formatting
This is a really powerful feature and hard to do with terminal output directly, so this is an impressive feature of rich.
from rich.table import Table
from rich.console import Console
table = Table("First table using rich!")
table.add_column("Language", justify="right", style="bright_yellow", no_wrap=True)
table.add_column("Year Initially Released", style="green")
table.add_column("Most recent version", justify="right", style="red")
table.add_row("", "Python", "1991", "3.9.1")
table.add_row("", "R", "1993", "4.0.3")
table.add_row("", "Java", "1995", "Java 15")
console = Console()
console.print(table)
What have you used Rich to do with your scripts?
I hope you found some useful tips here and that you go try out rich with your python applications!

Oh. I don't understand anything that you have said...
Absolutely and 100% completely Klingon..
However this is interesting and I absolutely need as much help as I can possibly get in surviving learning about python.
Hopefully I can trade you my secrets of Hive class and how to earn more here on the blockchain.
Left alone the fact that you can work and code here on the blockchain and make good money as well... Oh I've got friends that have needs all the time.
Sweet!
Vote for you! Right on I'm excited to invest in you.
Thanks mate, I appreciate that and yes, I'd love to combine more crypto/blockchain with my programming skills!
Come find me in the free compliments discord. Would that work?
I'm never on discord yet, haven't the time lately either, control projects are keeping me VERY busy. ha!
Yeah I've got to get to more trading and as well starting the coding education.
