IndexError: list index out of range pygame

Question

It says that the list index is out of range, and I don't know why. Does anyone know how to fix the problem?

Code for thing I'm importing

from os import walk
import pygame

def import_folder(path):
    surface_list = []

    for _, __, img_files in walk(path):
        for image in img_files:
            full_path = path + '/' + image
            image_surf = pygame.image.load(full_path).convert_alpha()
            surface_list.append(image_surf)

    return surface_list

Code for thing I'm using it in:

import pygame
from support import import_folder

class Player(pygame.sprite.Sprite):
    def __init__(self, pos):
        super().__init__()
        self.import_character()
        self.frame_index = 0
        self.animation_speed = 0.15
        self.image = self.animations['run'][self.frame_index]
        
        # Player Movement

        self.direction = pygame.math.Vector2(0, 0)
        self.speed = 8
        self.gravity = 0.8
        self.jump_speed = -16

    def import_character(self):
        character_path = '../graphics/character/'
        self.animations = {'idle':['idle'], 'run':[], 'jump':[], 'fall':[]}

        for animation in self.animations.keys():
            full_path = character_path + animation
            self.animations[animation] = import_folder(full_path)

@Rabbid76 what do I put in the part that says walk(path)? I tried putting os.chdir(os.path.dirname(os.path.abspath(__file__))) but it said NoneType object is not callable. — Daniel, Feb 27 '22 at 19:30

The frame_index becomes too large compared to the number of images for the "run" animation.

Try something like:

self.image = self.animations['run'][self.frame_index % len(self.animations['run'])]

if len(self.animations['run'])>0:
   self.animations['run'][self.frame_index]
else:

Your image files are not loaded properly. If the file path is not correct wrong, walk(path) returns nothing.
It is not enough to put the files in the same directory or sub directory of the project. You also need to set the working directory. The image file path has to be relative to the current working directory. The working directory is possibly different to the directory of the python script.
The name and path of the file can be retrieved with __file__ and the current working directory can be changed with os.chdir(path).

Add the following at the beginning of the main code to set the working directory to the same as the main script's directory:

import os
os.chdir(os.path.dirname(os.path.abspath(__file__)))
