[Python] TypeError: __init__() got an unexpected keyword argument 'size [duplicate]

How do I fix this unexpected keyword argument 'size'?


Traceback (most recent call last):
File "H:\Documents\Astro game\astro games6.py", line 73, in <module>
main()
File "H:\Documents\Astro game\astro games6.py", line 61, in main
new_asteroid = Asteroid(x = x, y = y,size = size)
TypeError: __init__() got an unexpected keyword argument 'size'


The full code:

import random
from superwires import games

games.init(screen_width = 640, screen_height = 480, fps = 50)

class Asteroid(games.Sprite):
""" An asteroid which floats across the screen"""
SMALL = 1
MEDIUM = 2
LARGE = 3
images = {SMALL : games.load_image("asteroid_small.bmp"),
MEDIUM : games.load_image("asteroid_med.bmp"),
LARGE : games.load_image("asteroid_big.bmp")}
speed = 2

def _init_(self, x, y, size):
"""Initialize asteroid sprite"""
super(Asteroid, self)._init_(
image = Asteroid.images[size],
x = x, y = y,
dx = random.choice([1, -1]) *Asteroid.SPEED* random.random()/size,
dy = random.choice([1, -1]) *Asteroid.SPEED* random.random()/size)

self.size = size


def update (self):
""" Warp around screen"""
if self.top>games.screen.height:
self.bottom = 0

if self.bottom < 0:
self.top=games.screen.height

if self.left > games.screen.width:
self.right = 0

if self.left < 0:
self.left = games.screen.width

class Ship(games.Sprite):
"""The player's ship"""
image = games.load_image("ship.bmp")
ROTATION_STEP = 3

def update(self):
if games.keyboard.is_pressed(games.K_LEFT):
self.angle -= Ship.ROTATION_STEP
if games.keyboard.is_pressed(games.K_RIGHT):
self.angle += Ship.ROTATION_STEP


def main():
nebula_image = games.load_image("nebula.jpg")
games.screen.background = nebula_image

for i in range(8):
x = random.randrange(games.screen.width)
y = random.randrange(games.screen.height)
size = random.choice([Asteroid.SMALL, Asteroid.MEDIUM, Asteroid.LARGE])
new_asteroid = Asteroid(x = x, y = y,size = size)
games.screen.add(new_asteroid)


the_ship = Ship(image = Ship.image,
x = games.screen.width/2,
y = games.screen.height/2)

games.screen.add(the_ship)

games.screen.mainloop()

main()


I have tried removing the size argument, but it caused more errors in the code. We also tried changing the size tag to something else to see if that helps and it didn't work either. So I'm stuck for what I need to do to make this code work. I am working on it for a class project in school. English is not my first language so I have had a classmate write this up.

Thank you.
