Hey, still a beginner in Python. I was wondering if anybody could help me out with all this info.
Im planning to make an actual game, but first i have to get classes/methods etc.
I thought maybe this would be some good classes:
Trainer, Pokemon, Moves, Stats, Type, Pokeball, Pokedex
There is so much stuff to incorporate i dont know what to put where.
any help would be great

The Pokemon game involves a lot of different things -- wandering around a map, talking to NPCs, battling Pokemon, managing your inventory, etc. I would pick one thing to start working on and grow the game from there.

For example, you might start with a Pokemon battle. You would need Pokemon with stats and several attacks and have a system where each Pokemon takes turns using an ability until one faints. Once you have that working, you could add in a Trainer who can swap between multiple Pokemon. From there, you might consider what happens when the battle ends. At that point, you would need to develop the Pokemon class to understand leveling and gaining new abilities and improved stats at certain levels. From there, you can add in items (e.g. Pokeballs, potions).

Before you make any game using python or any programming language you need to first map out the game, how you want to make it look, the characters and the fight scenes. From there making an oop game with class should be easy.

I have some extremely simple code for player sprite. Its over coded i think, still in process.
Anyway, I have a problem. Im loading a png image (spritesheet, col=2, row=4) and use the 1st column for the up/down/left/right orientation of the sprite. The 2nd column is the image in a walking position. I need to use that 2nd column to make the sprite look like he's walking. I was thinking to set all 8 images in the file beforehand and use it that way. Im using coordinates to cut parts and reassigning/updating rect. Now heres the problem. No matter how hard i try/think, i cant figure out how to switch between images. ..... constantly. Im saying that i need to switch the image with key.get_pressed (up down etc) respectively. For example, the coordinates for sprite facing down is (0,0) and the walking image of that is (0,64). Now i need to switch between these two while the down key is held.
Help plz!!
