goblin | A Content Management System Built in Pure Javascript | Carousel library

What I'm trying to do is make a function that subtracts the total value of another variable from the main one. I tried to create this but failed... I tried doing this.

I'm trying to figure out class mapping via xml in hibernate, following the tutorial from the official site, and I keep getting the same error - org.hibernate.boot.MappingNotFoundException: Mapping (RESOURCE) not found, as a result i cannot get SessionFactory and Session. I have thoroughly checked all the paths and project structure, tried using both maven and gradle but nothing has helped so far. I'm using postgres DB. Here's my project structure:

Here's pom.xml:

I am trying to make a bot that simulates a turn based battle, but i have no idea how to make a bot respond after i've sent the command. what i have tried for now is:

I'm making a discord bot and for the fight system I want the code to repeat the damage chunk if the monster isn't dead. I'm not sure how to do this but I know there's something you can do with a while true and break but I don't kno how to implement it. Here is the code:

I have no idea why this is happening, I have checked everything and all seems working. Here is the code( the error is about halfway down, I put some arrows next to it in brackets. I'm not sure if it's an indent issue or what. Before this there was an error just above on the "with open('mainbank.json', 'w') as f" bit.

I am trying to make a basic game where the goblin moves from left hits the side then goes back again. I am trying to check if the player sprite is overlapping with the goblin sprite when the player attacks, then do some damage to the goblin. Although my player is always on contact with the enemy even when he isn't close to coming in contact. Why is this happening?

So, I am making a simple game in which when the player collides with the enemy it's health is supposed to decrease with a graphic of a -5 popping up and then the game restarts. But when I start the programme the -5 pops up while it is not even supposed to and the rest of the screen stays black. And their is no error except a warning that has nothing to do with the messed up graphics. So, I am just going to paste the whole code as I think there is a problem with the player class, the scoring method and also with the blit method.

Got some code, and stumped on a question: How to resize image with pygame.transform.scale? Looked at the docs, but can't understand it. I'm puzzled on the player.py part.

So here's my code:

elves.py:

I have a list that might contains duplicated values, I want to find them and add some letters or numbers to them, but leave the other values alone.
For example:
input_list = ['A', 'B', 'C', 'A', 'D', 'D', 'A', 'E']
Expected output:
output_list = ['A1', 'B', 'C', 'A2', 'D1', 'D2', 'A3', 'E']
Is it possible to do this?


Edit:
Someone asked me to show the actual code, so I will put them here.
I'm really new to programming just about 2 weeks, so I'm sorry if I did anything stupid.
I was actually making a RPG as one of my exam in LPTHW, I have some classes of monsters, and instantiate them into a list.
They appears randomly and might be duplicated.
So if there are duplicated monsters, I need to add a letter in the end of their names to differentiate them.
For example like "Goblin A" and "Goblin B".
