Spot the error for the Newbie

Hello!!

Ok here is a code example i copied from a guide on Pygame.
It worked when i used IDLE and typed in line by line
But it doesnt work if I try running the code from a .py file

--error--
File "bouncyball.py", line 19
ballrect = ballrect.move(speed)
^
SyntaxError: invalid syntax

--code--
import pygame ,sys

pygame.init()

size = width, height = 320, 240
speed = [2, 2]
black = 0,0,0

screen = pygame.display.set_mode(size)
ball = pygame.image.load("e:\\ball.bmp")
ballrect = ball.get_rect()


while 1:

..for event in pygame.event.get():
.....if event.type == pygame.QUIT: sys.exit()

..ballrect = ballrect.move(speed)

..if ballrect.left < 0 or ballrect.right > width:
....speed[0] = -speed[0]

..if ballrect.top < 0 or ballrect.bottom >height:
....speed[1] = -speed[1]

..screen.fill(black)
..screen.blit(ball, ballrect)
..pygame.display.flip()


pygame.QUIT()




any ideas???????

p.s. ".." means tab,

I cant see anything from what the code but maybe it was lost when you posted it? Try posting the code again using Code-tags as discribed the sticky at the top of this forum .

Also, you may want to try changing...



to..



Just to see if that helps,

Mark.

error:
File "bouncyball.py", line 20
ballrect = ballrect.move(speed)

SyntaxError: invalid syntax

Much better.


Don't do this.
Do:

if you must.


ballrect.move() returns something? A new ballrect? Weird.

Not sure if this is your problem, but..

I have had similar problems with "syntax errors" which were entirely due to files mixing tab characters and spaces or just because one line has 3 spaces for indentation when 4 spaces are used in other places..

This often happens when pasting code from other sources (e.g. off a web-page). You can also cause problems if you switch editors and the editors are not configured the same way. (the use of tabs character/ number of spaces for tab).

Try loading the file into Idle then select the whole text (CTRL-A) the use the Format-"Untabify Region" menu option. Then save the file and try again. If you still get errors then search for odd indentation depths around the line reported.

I have also had indentation errors like this that only show up when a module has been included by another module.

Try to be consistent with other modules which typically use 4 spaces for each tab. You will save yourself problems in the future.
