But you have seen writestr(), haven't you?

ZipFile.writestr(zinfo_or_arcname, data, compress_type=None,

    Write a file into the archive. The contents is data, which may be
    either a str or a bytes instance;

No your're not. writestr() and ZipInfo are your friends, unless I
haven't understood what you're trying to do.
