python - What do? __init__() takes exactly 3 arguments (1 given)? -

-

this question has answer here:

here's error gives me along code lines specified. apologies past post.

traceback (most recent call last):   file "h:\users\daniel\desktop\final project\gold hunter.py", line 352, in <module>     main()   file "h:\users\daniel\desktop\final project\gold hunter.py", line 346, in main     score = game()   file "h:\users\daniel\desktop\final project\gold hunter.py", line 195, in game     pirate = pirate() typeerror: __init__() takes 3 arguments (1 given)

actual code

  main() line 352   score = game() line 346   pirate = pirate() line 195

pirate constructor gives me error nameerror: global name 'dx' not defined

class pirate(pygame.sprite.sprite):      east = 0      def __init__(self, screen, dx):         self.screen = screen         pygame.sprite.sprite.__init__(self)         self.image = pygame.image.load("king_pirate/running e0000.bmp")         self.image = self.image.convert()         trancolor = self.image.get_at((1, 1))         self.image.set_colorkey(trancolor)         self.rect = self.image.get_rect()         self.rect.inflate_ip(-50, -30)         self.rect.center = (0, random.randrange(30,450))         self.img = []          self.loadpics()         self.frame = 0         self.delay = 4         self.pause = self.delay         self.dx = dx

i agree lee's comment. cannot see class pirate: constructor clear __init__ function taking 3 arguments when define it. these self, argument1, argument2, when call pirate = pirate() on line 195, must provide 2 arguments (it self on own). need give argument1 , argument2 defined in constructor. post constructor more help. line 195 should pirate = pirate(argument1, argument2)

good luck!

i've been using 2 methods render data. the first one: function name($id,$name){ return '<div id="'.$id.'">'.$name.'</div>'; } echo implode($pdo->query("select id,name user")->fetchall(pdo::fetch_func,'name')); the second one: $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); foreach($users $user){ echo name($user->id,$user->name); } i don't understand how pdo::fetch_func works. tried figure out. however, not well-documented. could please explain fetch mode? , also, 1 performs better? thank you. both methods wrong , have learn how use templates , how separate business logic presentation logic. $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); tpl::assign('users', $users); is code business logic part. then in template <?php foreach $users $row): ?> <div id="<?=$...
