How can I get the number of lives change (pygame)?
Question: I'm new to python and pygame and so far ive managed to get everything working,
but cant work out how to make my lives go down.

If you haven't worked out its a simple fruit catching game.

I've managed to make my score go up. I've tried saying if the fruit is below a
certain x co ordinate take away a life but it doesn't work.

    
    
    import time
    import random
    import pygame
    from pygame import*
    pygame.init()
    myname=input('What is your name')
    #set the window size
    window= pygame.display.set_mode((800,600) ,0,24)
    pygame.display.set_caption("Fruit Catch")
    #game variables
    myscore=0
    mylives=3
    mouth_x=300
    fruit_x=250
    fruit_y=75
    fruitlist=['broccoli.gif','chicken.gif']
    #prepare for screen
    myfont=pygame.font.SysFont("Britannic Bold", 55)
    label1=myfont.render(myname, 1, (240, 0, 0))
    label3=myfont.render(str(mylives), 1, (20, 255, 0))
    #grapchics
    fruit=pygame.image.load('data/chicken.png')
    mouth=pygame.image.load('data/v.gif')
    backGr=pygame.image.load('data/kfc.jpg')
    #endless loop
    running=True
    while running:
        if fruit_y>=460:#check if at bottom, if so prepare new fruit
           fruit_x=random.randrange(50,530,1)
           fruit_y=75
           fruit=pygame.image.load('data/'+fruitlist[random.randrange(0,2,1)])
        else:fruit_y+=5
       #check collision
        if fruit_y>=440:
                if fruit_x>=mouth_x and fruit_x<=mouth_x+300 :
                        myscore+=1
                        fruit_y=600#move it off screen
                        pygame.mixer.music.load('data/eating.wav')
    
    
    
        #detect key events
        for event in pygame.event.get():
                if (event.type==pygame.KEYDOWN):
                    if (event.key==pygame.K_LEFT):
                            mouth_x-=55
                    if (event.key==pygame.K_RIGHT):
                            mouth_x+=55
    
        label2=myfont.render(str(myscore), 1, (20, 255, 0))
        window.blit(backGr,(0,0))
        window.blit(mouth, (mouth_x,440))
        window.blit(fruit,(fruit_x, fruit_y))
        window.blit(label1, (174, 537))
        window.blit(label2, (700, 157))
        window.blit(label3, (700, 400))
        pygame.display.update()
    


Answer: When checking for the collision, use `else`.

    
    
    #check collision
    if fruit_y>=440:
             if fruit_x>=mouth_x and fruit_x<=mouth_x+300 :
                 myscore+=1
                 fruit_y=600#move it off screen
                 pygame.mixer.music.load('data/eating.wav')
             else:
                 mylives-= 1
    

That should work.
