def count_fingers(hand: list): 
    count = len(hand)
    if count != 5:
        if count &lt; 5:
            raise Exception("Check if fingers missing, or just smart ass")
        else:
            raise Exception("Oh... oh no.")
    return count

You can do

if (count := len(hand)) != 5:
    # do something with "count"

Btw, looks much nicer

I'll use ternary operators when you force them into my cold, dead hands

[–] [email protected] 7 points 1 year ago (1 children)

It's not the ternary operator, it is the walrus operator introduced in Python 3.8 if I'm correct

[–] [email protected] 5 points 1 year ago

You are correct. I came back to say that I'll use the walrus operator when it's pushed into my cold, dead hands, but... I might actually use it, now that I've refreshed myself on it.
