如何解压缩所有以.zip结尾的文件夹/文件，并从每个压缩的文件夹中提取“ file.txt”文件

Question

我的代码当前将一个zip文件夹解压缩，并找到名为file.txt的文件并将其解压缩。 现在，我需要解压缩多个扩展名为.zip的文件夹。 我试图使用类似于我需要执行的代码，但问题是现在我必须在每个.zip文件夹中找到一个名为file.txt文件，然后仅提取该文件。 也可以将file.txt存储到一个单独的具有相同名称的文件夹中。 预先感谢您的宝贵时间。

#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)
