[PyGame] Terrible Sprite controls, need help.

[michael1789]

I did all your changes and it runs, but nothing happens and game window freezes. It keeps running even after the window freezes, but I don't think it's taking input.

import pygame
import math
pygame.init()

window = pygame.display.set_mode((800, 800))
clock = pygame.time.Clock()
black = (0, 0, 0)

class Ship(pygame.sprite.Sprite):
    def __init__(self, position, anchor="center"):
        
        self.original_image = pygame.Surface((10, 20), pygame.SRCALPHA)
        self.original_image.fill((100, 200, 200))
        self.original_image.set_colorkey(black)
        self.image = self.original_image.copy()
        self.rect = self.image.get_rect(**{anchor: position})
        self.position = pygame.Vector2(self.rect.center)
        self.start_position = pygame.Vector2(position)
        self.angle_change = False
        self.angle = 180

        self.max_speed = 0.1
        self.thrust = 0.00005

        self.friction = 0.999

                self.speed = 0
 
        if keys[pygame.K_LEFT] or keys[pygame.K_a]:
            self.angle = (self.angle + self.rotate_speed * delta) % 360
            self.update_rotation()
        elif keys[pygame.K_RIGHT] or keys[pygame.K_d]:
            self.angle = (self.angle - self.rotate_speed * delta) % 360
