Run 2 pygame windows with 2 different processes [duplicate]

I need to to build an application that has multiple windows. In one of these windows, I need to be able to play a simple game and another window has to display questions and get response from a user that influences the game.
(1) I was wanting to use pygame in order to make the game. Is there a simple way to have pygame operate with multiple windows?
(2) If there is no easy way to solve (1), is there a simple way to use some other python GUI structure that would allow for me to run pygame and another window simultaneously?

The short answer is no, creating two pygame windows in the same process is not possible (as of April 2015). If you want to run two windows with one process, you should look into pyglet or cocos2d.
An alternative, if you must use pygame, is to use inter-process communication. You can have two processes, each with a window. They will relay messages to each other using sockets. If you want to go this route, check out the socket tutorial here.

Internally set_mode() probably sets a pointer that represents the memory of a unique display. So if we write:
screenA = pygame.display.set_mode((500,480), 0, 32)
screenB = pygame.display.set_mode((500,480), 0, 32)
For instance we can do something like that later:
screenA.blit(background, (0,0))
screenB.blit(player, (100,100))
both blit() calls will blit on the same surface. screenA and screenB are pointing to the same memory address. Working with 2 windows is quite hard to achieve in pygame.

Yes, that is possible. SDL2 is able to open multiple windows. In the example folder you can take a look at "video.py".
https://github.com/pygame/pygame/blob/main/examples/video.py
"This example requires pygame 2 and SDL2. _sdl2 is experimental and will change."

I've been trying to do this for a few days now, and I'm finally making progress. Does this count as simple? Or even as "being in" pygame. In this exampe I never even call pygame.init() That just seems to get in the way. The event pump is running (for mouse and keyboard) but not all the normal events seem to be coming thru (FOCUSGAINED and LOST in particular). In this example each window renders it status (size, position, etc) to it's self. I also have versions where I mix SDL windows with the pygame display. But those involve encapsulating a Window rather than extending it.
In order to draw on these windows you can draw on a vanilla surface as usually and then use the Renderer associated with the window to create a texture that will update the the window. (texture.draw(), renderer.present). You dont't use display.update() or flip() because you you aren't using the pygame display surface.
The X11 package is just my experimental windowing stuff and has nothing to do with X11. I think all my imports are explicit so it should be easy to figure out what the missing pieces are.

Referencing an event variable before assignment error and I dont know how to fix it

In the help() method:
def help(self):
...
if event.type == MOUSEBUTTONDOWN:
...
while True:
...
for event in pygame.event.get():
event is defined in the for loop, but you're referring to it before that.
One way to fix it is to move the if event.type == MOUSEBUTTONDOWN statement inside the for loop.
Or, since .help() is only called from the bottom event loop where the event is already known to be MOUSEBUTTONDOWN, perhaps you could remove the if statement altogether?
(BTW, I thought the error message was pretty clear; did you not understand it?)

I'm building a game using PyGame and Python 3.4. I am having an issue with what appears to be the module itself and not the actual code I have because the full error is:

Thanks in advance for the help!

It is the wrong way around for a start. playerhit = pygame.sprite.spritecollide(ebullet, psprite, True) - the function definition is spritecollide(sprite, group, dokill, collided = None) so the player should be first, and then the bullet group.
Also please post the Sprite.py code.

Main game loop ends here and sends me back to my menu just like I want. However, when I try to import grab again from my menu then nothing happens. I went and searched for "Python import cycle" from Google and I discovered a few things but i'm still stuck. There must be an easier way to make Grab.py loop from this:
def run_game():
import Grab
Any help is very much appreciated.
Regards HJ.

Generally speaking, use import to load the definition of constants, functions or classes. Do not use it to run a bunch of statements. Call a function to run a bunch of statements.
For efficiency, Python only imports modules once. After it is loaded the first time, the module is cached in sys.modules. Every time Python encounters an import statement it check if the module is in sys.modules and uses the cached module if it exists. Only if the module is not in sys.modules does Python execute the code in the module. Thus the code in the module is never executed more than once. That is why import Grab does not execute the code in Grab.py the second time the import statement is reached.
So, instead, refactor Grab.py to put all the code you wish to run multiple times inside a function:
import pygame, time, math, sys, random, os
from pygame.locals import *
pygame.init() #make pygame ready
pygame.joystick.init() # <-- Note you need parentheses to *call* the init function

and then change
import Grab
to
import Grab
Grab.main()
You could move import Grab to the top of Menu.py; generally speaking it is recommended to put all the import statements at the top of any Python script or module.

Why aren't sprites in Pygame blitting to the screen in Windows 7?

I've been working on a Space Invaders-type game for the past week or so, and it's coming along really well, but for some reason when I run the game on my Windows computer (the one I prefer to code on), most of the sprites don't show up, or only show up when they're moving in a certain direction on the screen. When I run the exact same code on my Mac, everything blits and updates perfectly. Is this a known issue that pygame just doesn't get along with Windows? The fact that everything works on my Mac makes me think that it's not an issue with my code, but just in case, here's my main loop:
dirty = []
score_label = font.render("Score: " + str(score), 1, (255,215,0))
level_label = font.render("Level: " + str(level), 1, (255,215,0))
screen.blit(background,(10,10),(10,10,330,30))
screen.blit(score_label,(10,10))
screen.blit(level_label,(200,10))
dirty.append((10,10,330,30))
# New level
if isEmpty(enemies):
dirty.append((400,300,150,30))
for i in bullets:
dirty.append(i.pos)
screen.blit(background,(i.pos[0],i.pos[1]),i.pos)
bullets.remove(i)
if pauseCounter == 40:
screen.blit(background,(400,300),(400,300,150,30))
pauseCounter = 0
jump = 30
level+=1
for x in range(1,6):
for y in range(11):
enemies[x-1].append(Sprites.Enemy(enemy_values[6-x],(60*y,40*x),6-x))
for x in range(len(enemies)):
for e in enemies[x]:
dirty.append(e.pos)
else:
upLevelLabel = levelFont.render("Next Level!",1,(255,215,0))
screen.blit(upLevelLabel,(400,300))
pauseCounter += 1
# Player input
dirty.append(o.pos)
screen.blit(background,(o.pos[0],o.pos[1]),o.pos)
keys = pygame.key.get_pressed()
if keys[K_a] and o.pos[0]-10 >= 0:
o.speed = -10
o.move()
if keys[K_d] and o.pos[0] <= 907-o.pos[3]-10:
o.speed = 10
o.move()
dirty.append(o.pos)
screen.blit(o.image,o.pos)
# Add bullets
for event in pygame.event.get():
if event.type == pygame.QUIT: sys.exit()
if event.type == pygame.KEYDOWN:
if event.key == K_SPACE:
bullets.append(Sprites.Bullet(bullet,(o.pos[0]+28,o.pos[1])))

if isEmpty(enemies) == False:
for x in range(len(enemies)):
if len(enemies[x]) > 0:
temp = enemies[x][0]
if b.pos[1] in range(temp.pos[1],temp.pos[1]+temp.pos[3]):
for e in enemies[x]:
if b.pos.colliderect(e.pos):
score += e.val*10
screen.blit(background,(b.pos[0],b.pos[1]),b.pos)
screen.blit(background,(e.pos[0],e.pos[1]),e.pos)
dirty.append(e.pos)
dirty.append(b.pos)

# Moves enemy at appropriate pace, drops bombs
if enemyMoves == jump:

Thanks in advance!

Maybe you should try:
dirty.append(Rect(x,y,width,height))
or
dirty.append(pygame.Rect(x,y,width,height))
Remember, you are passing a rectangle list to pygame.display.update(dirty) and so try and stick to pygame rectangles
instead of:
dirty.append((x,y,width,height))

Thank you to furas, it was the partial update that was causing the error!
