Question

If I do something like this:

from zipfile import ZipFile 

zip = ZipFile(archive, "a")  

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

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?

Answer 1

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()
