python如何附加到zip存档中的文件 [英] python how to append to file in zip archive

问题描述

如果我做这样的事情:

from zipfile import ZipFile 

zip = ZipFile(archive, "a")  

for x in range(5):
    zip.writestr("file1.txt", "blabla")

它将创建一个包含5个文件的存档，所有文件均名为"file1.txt".我要实现的是有一个压缩文件，每个循环迭代都会在其中添加一些内容.没有某种辅助缓冲区是否可以解决?

It will create an archive with 5 files all named "file1.txt". What I want to achieve is having one compressed file to which every loop iteration appends some content. Is it possible without having some kind of auxiliary buffer and how to do this?

推荐答案

使用zipfile包是不可能的，但是

It's impossible with zipfile package but writing to compressed files is supported in gzip:

import gzip
content = "Lots of content here"
f = gzip.open('/home/joe/file.txt.gz', 'wb')
f.write(content)
f.close()
