battleship | Simple battleship game built in Pygame | Game Engine library

I need to make a battleship game in JS with Prompt and I cant for the life of Me figure it out. Example is attached: https://www.youtube.com/watch?v=xSpJLx72PQY Quality isnt very good Here is some code

I need to add 3 functions to my battleship game how would I go about adding the following;

1 Storing Guesses and then telling the player they have already guessed that number

1. Telling them to only enter numeric characters if they enter non numeric

2. After a certain amount of rounds they loose.

I feel like this is basic to implement but Im confused. Code

The issue: I'm recreating Battleship within a console app and the user input is in the format 'letter-number-letter-number' (A1E1). The program needs to find if the second letter's index when added or subtracted by 4 is the same as the first letter to validate that the user input is of an accepted length to the ship type. However, when my code runs the index is outside the bounds of the array.

For example, a Cruiser is 5 spaces long. Therefore, to place the Cruiser horizontally, the numbers must be the same and the letters must have a distance of 4 elements from one another within the validInputs array.

Some input's work, for example: A3E3 works, however, E3A3 will go outside the bounds.

I started to Use Python for Almost a Week. I'm Creating a Game and its name is "Space Invaders". I'm trying to add more Enemies instead of One. I'm using PyGame. Python Version 3.8.7. I have 2 problems. First: When I run the Python File in Terminal I only get a Black Screen.

I'm making a 1-D battleship game where there is only 1, 1x10 row so I want to generate a random #(0-10) each game but the next 2 numbers must be right beside it because its a ship. I've been trying lots of different options with no success so far. This code grabs 3 random #'s with no-repeats, also important, but the numbers aren't next to each other. Any help would be much appreciated.
