I've been searching on how to select items from a list via input and the last part of your tutorial explained just that! Thanks very much 😁

Very useful. I could not find a good explanation about it anywhere.

🚀 Your video was incredibly helpful, Fabio! As a beginner developer, learning how to validate user inputs in Python seemed daunting, but your clear explanations and practical examples made it so much easier to grasp. Now I feel more confident in handling user inputs and ensuring the integrity of my programs. Thank you for sharing your expertise and making coding more accessible for everyone! 💪❤

Why a question arrives when i do input?

[Meyaal]

Hello Fabio! This is amazing tutorial for my understandig! I really enjoed it😀 I am new at coding, how can I implement that on the hangman game the one that you created in the other video. I need to make the code to handle empty and invalid inputs from users without losing lifes if you understand what I mean. I need that specific for the hangman game that you have created because I don’t know how to implement that by my own. Plaese help me 🙏🏼

when i entered break it throws an error that break can be used only within a loop. I checked everything seems ok. How to fix it?

[gamerbase]

and what if i want a certain word ? how can i make it so everything but this word gets marked as Invalid?

[jayl]

I trying to add to this to a calculator i am making in python. But i having difficulty applying it to the (num 1 and num 2 user input portion if the user does enter a integer. it just returns an error, its not attached to the user input portion. How do i error check num 1 and num 2 for non interger values. i did use try and error but just had indentation issues. Thanks

Fabio, can you Store strings ‘stone’, ‘paper’, ‘scissors’ in a list
Ask the user to input their choice (validate)
Pick a random item from the list to represent the computer 
Use if, elif commands to check who wins
Display who won on the screen.
