[PyGame] Input is not defined

[Forno_Gamer]

Hello, I'm having a problem. I'm trying to make the "A" key do the basic movement of moving my player to the side. This error occurs that says that 'K_a' is not defined. I'm basing this entirely on my understanding, on the pygame DOC, and on examples from the internet, so I'm not really understanding what happened because in the pygame doc, the A key is written 'K_a'. Could someone explain it to me?

this function is in the player

def _inputs(self, events):
		if events.type == pygame.key.get_pressed()[K_a]:
			self.posX -= speed

this function is in the game

def _events(self):
		for event in pygame.event.get():
			self.player._inputs(event) # player Input (Player is in a player variable)
			if event.type == pygame.QUIT:
				self.running = False

Error:
NameError: name 'K_a' is not defined

Without seeing all the code kind of hard to help. Here is a basic structure of moving objects in pygame.

import pygame

pygame.init()

window = pygame.display.set_mode((800,600))
clock = pygame.time.Clock()

running = True

class Player(pygame.sprite.Sprite):
    def __init__(self):
        pygame.sprite.Sprite.__init__(self)
        self.image = pygame.Surface((50,50))
        self.image.fill('red')
        self.rect = self.image.get_rect()
        self.rect.centerx = 400
        self.rect.centery = 570
        self.speed = 0

    def update(self):
        self.speed = 0
        key = pygame.key.get_pressed()
        if key[pygame.K_a] or key[pygame.K_LEFT]:
            self.speed = -10

        if key[pygame.K_d] or key[pygame.K_RIGHT]:
            self.speed = 10

        self.rect.centerx += self.speed

        if self.rect.left <= 0:
            self.rect.left = 0
        if self.rect.right >= 800:
            self.rect.right = 800

sprites = pygame.sprite.Group()

player = Player()

sprites.add(player)

while running:
    window.fill('black')

    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False


    sprites.update()
    sprites.draw(window)
    pygame.display.update()
    clock.tick(60)

pygame.quit()

You don't have a variable called K_a. Did you intend to write the string "K_a"?

Never mind. See below.

K_a is a variable in the pygame module, not your module.

import pygame

try:
    print(K_a)
except NameError as ex:
    print(ex)

print(pygame.K_a)

Output:
pygame 2.1.3.dev8 (SDL 2.0.22, Python 3.11.1)

Use pygame.K_a instead of K_a
