Read a file within an archived archive (without extracting)-CodePudding

What I am trying to do is to read a file located in an archived archive as shown below: I want to access a "document.txt" file

Code 1:

import zipfile

with zipfile.ZipFile("archive.zip", mode="r") as archive:
   with zipfile.ZipFile("archive2.zip", mode="r") as archive2:
      text = archive2.read("document.txt")
      print(text) #FileNotFountError: [Errno 2] No such file or directory: 'archive2.zip'

Code 2:

import zipfile

with zipfile.ZipFile("archive.zip/archive2.zip", mode="r") as archive:
   text = archive.read("document.txt")
   print(text) #FileNotFountError: [Errno 2] No such file or directory: 'archive.zip/archive2.zip'

None of the above works. How can I read a "document.txt" file that is located in an "archive2.zip", which in turn is located in an "archive.zip" file without extracting anything? Thank you very much.

You need to open first then read it. Ex:-

import zipfile
with zipfile.ZipFile("archive.zip/archive2.zip", mode="r") as archive:
   text = archive.open("document.txt").read().decode()
   print(text)

You first need to open archive.zip, then read the raw archive2.zip file and finally read the document within that zip file.

import zipfile

with zipfile.ZipFile(r"archive.zip", "r") as archive:
    with zipfile.ZipFile(archive.open(r"archive/archive2.zip", "r")) as archive2:
        doc = archive2.open("archive2/document.txt")
        content = doc.readlines()
        print(content)
