How to unzip all folders/files that end in .zip and extract “file.txt” file from each zipped folder

Question

My code currently unzips one zip folder and finds the file called file.txt and extracts it. Now I need to unzip multiple folders that have the extension .zip. I have tried to use code similar to what I need it to do but the problem is that now I have to find a file called file.txt in each of those .zip folders and extract that file only . Also to store file.txt into a separate folder that has the same name where it came from. Thank you in advance for your time.

            if fileName.endswith('.txt'):
                zipObj.extract(fileName, 'storage')

#THIS WORKS 

Answer 1

import glob
import os
from zipfile import ZipFile

def main():
    for fname in glob.glob("*.zip"):  # get all the zip files
        with ZipFile(fname) as archive:
            # if there's no file.txt, ignore and go on to the next zip file
            if 'file.txt' not in archive.namelist(): continue

            # make a new directory named after the zip file
            dirname = fname.rsplit('.',1)[0]
            os.mkdir(dirname)

            extract file.txt into the directory you just created
            archive.extract('file.txt', path=dirname)
