在python中从zip加载音频文件时出错 [英] Error when loading audio file from zip in python
问题描述
我正在制作一个游戏,我需要从 .zip 文件中加载一些受密码保护的音频文件,但出现此错误:
I am making a game, and I need to load some password protected audio files from a .zip file, but I get this error:
io.UnsupportedOperation: seek
io.UnsupportedOperation: seek
io.UnsupportedOperation: seek
b'hey you did it!' #THIS IS FROM THE PROGRAM
Traceback (most recent call last):
File "C:\Python36\lib\zipfile.py", line 849, in read
data = self._read1(n)
File "C:\Python36\lib\zipfile.py", line 917, in _read1
data += self._read2(n - len(data))
File "C:\Python36\lib\zipfile.py", line 949, in _read2
data = self._fileobj.read(n)
File "C:\Python36\lib\zipfile.py", line 705, in read
self._file.seek(self._pos)
AttributeError: 'NoneType' object has no attribute 'seek'
这是我下面的代码:
from zipfile import ZipFile
from PIL import Image
from io import BytesIO
import pygame
from pygame.locals import *
import pyganim
import sys
pygame.init()
root = pygame.display.set_mode((320, 240), 0, 32)
pygame.display.set_caption('image load test')
#THIS IS HOW TO LOAD IMAGES (WORKS)
with ZipFile("spam.zip", 'r') as archive:
mcimg = archive.read('a.png', pwd=b'onlyforthedev')
mc = pygame.image.load(BytesIO(mcimg))
anime = pyganim.PygAnimation([(mc, 100),
(mc, 100)])
anime.play()
#THIS IS HOW TO LOAD MUSIC (DOES NOT WORK)
with ZipFile('spam.zip') as zippie:
with zippie.open('zora.mp3', pwd=b'onlyforthedev') as zora:
pygame.mixer.music.load(zora)
pygame.mixer.music.play(-1)
#THIS IS HOW TO LOAD TEXT (WORKS)
with ZipFile('spam.zip') as myzip:
with myzip.open('eggs.txt', pwd=b'onlyforthedev') as myfile:
print(myfile.read())
while True:
for event in pygame.event.get():
if event.type == QUIT:
pygame.quit()
sys.exit()
root.fill((100, 50, 50))
anime.blit(root, (100, 50))
pygame.display.update()
如何加载声音文件而不引发此类错误?什么是寻求"?
What can I do to load sound files without raising such an error? And what is 'seek'?
推荐答案
我在 python 3.6 上也遇到这个错误.
I also get this error on python 3.6.
我猜pygame.mixer.music.load
调用zippie
上的seek
方法,这是一个ZipExtFile
.
I am going to guess that pygame.mixer.music.load
calls the seek
method on zippie
, which is a ZipExtFile
.
从 python 3.7 ZipExtFile
对象现在有一个 seek 方法.我认为如果您升级到 python 3.7.2 或更新版本,那么您的错误应该会消失.
From python 3.7 ZipExtFile
objects now have a seek method. I think that if you upgrade to python 3.7.2 or newer, then your error should go away.
