f-string error message

I am currently using Python 3.11.4. First I want to say: f-strings are great!  I use them all the time, mostly but by no means exclusively for debug messages.  And in 3.12 they will get even better. And the improved error messages in Python (since 3.9) are great too!  Keep up the good work. How

What sort of exception when a class can't find something?

What sort of exception should a class raise in __init__() when it can't find an appropriate set of data for the parameter passed in to the class instantiation? E.g. I have a database with some names and address in and have a class Person that gets all the details for a person given their name.

Why do I always get an exception raised in this __init__()?

I'm obviously doing something very silly here but at the moment I can't see what. Here's the code:- #!/usr/bin/python3 # # # GPIO # import gpiod # # # Simple wrapper class for gpiod to make set and clearing outputs easier # class Gpiopin:

Forward References

I am attempting to use forward references in my program and I am failing. This also does not work with the older way of putting the name of a class as a string. Here is some sample code: from __future__ import annotations from dataclasses import dataclass from typing import TypeAlias ColorDef:

iterations destroy reversed() results

Hi, reversed() results are fine until iterated over, after which the results are no longer available. This was discovered after using something like this: rev = reversed( sorted( list ) ) sr = sum( 1 for _ in rev ) # rev is now destroyed So reversed() results can only be iterated once unlike so

Finding good documentation for gpiod

I am using the gpiod package for manipulating GPIO inputs/outputs on a Beaglebone Black SBC (like a Raspberry Pi but with more flexible I/O). Mostly I am managing to get things to work as I want but better documentation of gpiod would be a great help. For example, when one has found an I/O pin (a
