I am trying to make a game in pygame and want to add apples at random places but the random module is not working. I tried looking online but the guy there was able to use this without any problem
My code and The output is down below

but the error is:
Next time write your code and errors directly in your question body, not as a screenshot.
You must have assigned random to a tuple somewhere between import random to the lines you posted.

I'm new to python and I'm trying following along with a tutorial that uses PyGame to create a snake like game. For some reason my boundaries are not working. It may be something simple but I can't see any reason why it wouldn't work. I don't get any errors, the snake just goes past the boundaries and the game doesn't end.

I was trying to add 'apples' in my snake game. However I was troubled in doing so. Any help debugging code would be very much appreciated! I'm getting some error on lines; 94,42 and 218 something has gone horribly wrong with the randrange stuff.
http://i63.tinypic.com/1h4ggj.png <----- To See
the error happens in
randAppleY = random.randrange(display_height-block_size, 0)
As the error stack trace indicates that randrange function got parameters start=580, stop=0. From inspecting the source file for this function shows that the default value for step is 1.
This is causing the problem as 0 is less than 580 and connot be reached by adding 1 (step parameter) any number of times.
What you can do to fix this is either pass step parameter as -1
randAppleY = random.randrange(display_height-block_size, 0, -1)
Or pass the smaller value as start and larger value as stop parameter
randAppleY = random.randrange(0, display_height-block_size)

I'm using 2.7.10 on pygame and I can't understand why the right keeps going down instead of right. The left works perfect. I can't find any issues relating, so does anyone know what is wrong with this?
import pygame
pygame.init()
GameDisplay = pygame.display.set_mode((800, 600))
White = (255,255,255)
Black = (0,0,0)
Red = (255,0,0)
pygame.display.set_caption('Test')
PyQuit = False
lead_x = 300
lead_y = 300
while not PyQuit:
for event in pygame.event.get():
if event.type == pygame.QUIT:
PyQuit = True
if event.type == pygame.KEYDOWN:
if event.key == pygame.K_LEFT:
lead_x -= 10
if event.key == pygame.K_RIGHT:
lead_y += 10
GameDisplay.fill(White)
pygame.draw.rect(GameDisplay, Black, [lead_x,lead_y,10,10])
pygame.display.update()
pygame.quit()
quit()
Instead of:
lead_y += 10
Try:
lead_x += 10
Use lead_x for horizontal and lead_y for vertical.
if event.key == pygame.K_RIGHT:
lead_y += 10'
You are making the lead_y += 10 when you should be adding 10 to the x coordinate
if event.key == pygame.K_RIGHT:
lead_x += 10'

I checked the problem a couple of times and focused mostly on the quit loops, but still nothing.
Remove one indent from your quit() call. This will ensure it is called only after the loop exits.
Best of luck, and happy coding!
So I'm trying to print "you lose" to the screen when the user moves a box off the playable screen, however this doesn't seem to work unless I call it from outside my main while loop. I have defined a function to handle the creation of the text, the rendering and 'blit'ing of it, although this has no effect when it is called from inside the while loop however it does when it is called from outside it at the bottom. I have checked and the function is executed from both locations, though it only seems to work from one.

From AirThomas comment, this is working. Outside of the while loop, put this statement.
For score board:
text = pygame.font.SysFont("None", 30)
score=0
text1=text.render("{}".format(score), True,(255,255,255))
while running:
screen.fill((0, 0, 0))
#codes
#codes
#codes
if sneakeatssomething:
score += 1
text1=text.render("{}".format(score), True,(255,255,255)) #rendering the score again
#codes
#codes
screen.blit(text1,(275,6))#showing the score
pygame.display.flip()
clock.tick(150)
This is updating the score when sneak eats and printing it to the pygame screen
