While we will happily help you with your problem, your homework is something you will need to do. With that, we can’t help you figure out where the problem is with your code if we can’t see your code and understand what it is supposed to be doing. If you share the code (please, don’t forget to put it in a Markdown code block with “```” on the line before and after the code) we can take a look and point you in the right direction.

"number_1 = str(input())

number_2 = str(input())

number_3 = str(input())

highest = list(number_1 + number_2 + number_3)

print(max(highest))"
here my code and the directive of this homework is to create the code for find and print the highest number in the list that I insert as you can see in the code. (Sorry this is my first time in here)

thank you very much sir

thank you now I got the answer right( 15 attempts) from chat gpt
thanks again

list(3) simply is not the same as [3]. When calling list, you pass it some iterable of values, not just the value(s) you want in the list.
