Frustrated that every beginner tutorial skips error handling entirely

Ngl I've been learning Python for about 3 months now and I keep seeing these YouTube tutorials where they code something and it works perfectly first try. But when I type the same code I get a stupid KeyError or something breaks. Then I look through the comments and nobody even mentions try-except blocks or validating inputs. Why does nobody teach you how to fail gracefully? I spent 2 hours yesterday debugging a script because I didn't check if a file existed before opening it. Has anyone else noticed this gap in beginner content, or am I just picking bad tutorials?

The most practical thing I ever did was just start wrapping risky code in try-except blocks right from the beginning even if it looks ugly. Python's official docs actually have a whole section on errors that most beginners skip, but reading it saves so much time later. Honestly just get into the habit of printing out the error message with `except Exception as e` so you can actually see what went wrong instead of guessing.

Exactly what brooket43 said is what finally clicked for me. A buddy of mine spent a whole weekend losing his mind over a script that kept bombing because of a simple typo in a dictionary key, and he only caught it by throwing in a basic `except Exception as e` to print what was actually wrong.

Spent a whole weekend on a typo. That is exactly the kind of thing that makes you want to throw your laptop out a window. I once chased a bug for two days only to find I had a lowercase 'l' where I needed an uppercase 'I'. A simple print statement would have saved me 48 hours of my life I'll never get back.
