python - 需要帮助在我的pygame代码上切换音乐背景

Question

图片正在尝试切换背景音乐
触底，当触顶时回到第一个。什么时候
我尝试将其放在while #formula中，然后每次都会重置
它下降了一点，那不是我想要的。
您能帮我弄清楚如何放置此代码:

pygame.mixer.music.load('song1')
pygame.mixer.music.play(-1, 0.0)

pygame.mixer.music.load('song2')
pygame.mixer.music.play(-1, 0.0)

在下面的代码中，并按照我在此处的说明进行切换？
如果我忘了解释你需要知道的事情
请告诉我。

import pygame, sys
from pygame.locals import *

pygame.init()

FPS = 200
fpsClock = pygame.time.Clock()

DISPLAYSURF = pygame.display.set_mode((400, 400), 0, 0)
pygame.display.set_caption('Verkefni 21')

WHITE = (255, 255, 255)
clownx = 10
clowny = 10
direction = 'right'
stefna = 'niður'

while True:
DISPLAYSURF.fill(WHITE)
if stefna == 'niður':
    if direction == 'right':
        clownImg = pygame.image.load('sarah.jpg')
        clownx += 5
        if clownx == 320:
            clowny += 10
            direction = 'left'
            clownImg = pygame.image.load('john.jpg')
        if clowny == 300:
            stefna = 'up'
            soundObj = pygame.mixer.Sound('bomb.wav')
            soundObj.play()
            import time
            time.sleep(2) # wait and let the sound play for 1 second
            soundObj.stop()

    elif direction == 'left':
        clownImg = pygame.image.load('john.jpg')
        clownx -= 5

            clowny -= 10
            direction = 'left'
            clownImg = pygame.image.load('terminator.jpg')
        if clowny == 0:
            stefna = 'niður'
            soundObj = pygame.mixer.Sound('bomb.wav')
            soundObj.play()
            import time
            time.sleep(2) # wait and let the sound play for 1 second
            soundObj.stop()
    elif direction == 'left':
        clownImg = pygame.image.load('terminator.jpg')

            stefna = 'niður'
            soundObj = pygame.mixer.Sound('bomb.wav')
            soundObj.play()
            import time
            time.sleep(2) # wait and let the sound play for 1 second
            soundObj.stop()

DISPLAYSURF.blit(clownImg, (clownx, clowny))

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

pygame.display.update()
fpsClock.tick(FPS)

切换歌曲时，请输入pygame.mixer.music.stop()。
