Python getting back to the first function

I am doing a Photobooth with printing (and uploading) option. This project presents itself like this: Start screen with instructions --> preview results screen --> user chooses either to print or restart (or the timeout chooses restart for the user)

If the user chooses print then, printing is done, and a message is displayed (sleep method) before going back to the start screen.

Now, i have one main issue: Getting back to the start screen...

The simplified code is here:

def PreviewMontage(MontageFile):
    global LastTap
    LastTap = time.time()
    print("Session ID:", SessionID)
    print("Show something.")
    preview = pygame.image.load(MontageFile)
    PILpreview = Image.open(MontageFile)
    previewSize = PILpreview.size # returns (width, height) tuple
    #added /1.5
    ScaleW = AspectRatioCalc(previewSize[0]/1.5, previewSize[1]/1.5, SCREEN_HEIGHT)
    preview = pygame.transform.scale(preview, (ScaleW, SCREEN_HEIGHT))
    SetBlankScreen()
    background.blit(preview, (SCREEN_WIDTH/2-ScaleW/2, 0))
    PrintScreen()
    #inserting conditions here - get mouse
    camera.stop_preview()
    UpdateDisplay()
    Wait()
    return

def Wait():
    clock = pygame.time.Clock()
    waiting = True

    while waiting:
        time = 60
        time = time -1 
        for event in pygame.event.get():
        if event.type == pygame.MOUSEBUTTONDOWN and event.button == LEFTMOUSEBUTTON:
            x, y = event.pos
            print("You pressed the left mouse button at (%d, %d)" % event.pos)
            LeftMouseButtonDown(x, y)
        if time == 0:
           waiting = False
return

I encounter the problem of getting back to the main screen, it seems that the Wait() function never ends...

You are setting the time to 59 on every iteration of your while loop. It means time never reaches 0 and the loop is infinite.

Fix it by declaring time = 60 outside the while()
