Question

我试图通过指定目录名来提取文件。但是我提取的目录由于某种原因没有提取的文件。输出显示已成功创建zipfile但未成功完成提取。

import os, shutil, send2trash, zipfile

with open('C:\\Users\\aryan\\os.walk_2.txt', 'a') as f:
    for folder, subfolder, file in os.walk(r'C:\Users\Public\Downloads\coding'):
        print('*' * 60,file=f)
        print('THE NAME OF THE FOLDER IS {0}'.format(folder), file=f)
        print('*' * 60,file=f)


        for subfolders in subfolder:
            print('SUBFOLDER {0} CONTAINS FOLLOWING FOLDERS {1}'.format(folder, subfolders), file=f)

        for filenames in file:
            print('FOLDER {0} CONTAINS FOLLOWING FILES {1}'.format(folder, filenames), file=f)
            if folder == r'C:\Users\Public\Downloads\coding\Python':
               if filenames == 'anti_vowel.py':
                  zip =zipfile.ZipFile(r'C:\Users\aryan\python_files.zip','w')


                 zip.write(r'C:\Users\Public\Downloads\coding\Python\anti_vowel.py', compress_type=zipfile.ZIP_DEFLATED)
                 print (zip.namelist())

                 zip.close()
                 print('LOOKS LIKE ZIP FILE IS CREATED')
                 extract_dir='C:\\Users\\aryan'
                 os.chdir('C:\\Users\\aryan')
                 if os.path.exists(extract_dir):
                    zip=zipfile.ZipFile('python_files.zip')
                    zip.extractall(extract_dir)
                    print(os.getcwd())
                    print(os.listdir())
                    for folder, sub, filename in os.walk(r'C:\Users\aryan'):
                        for file in filename:
                          if file == 'python_files.zip':
                              print ('ZIP FILE STILL PRESENT')
                              #os.remove('python_files.zip')
                              if file == 'anti_vowel.py':
                                  print('EXTRACTED FILE IS PRESENT')
                              else:
                                  print('EXTRACTED FILE IS MISSING')

                   zip.close()
                else:
                   print ('THE DIR TO WHICH FILE NEEDS TO BE EXTRACTED IS MISSING')

输出： -

 ZIP FILE STILL PRESENT
 EXTRACTED FILE IS MISSING

Answer 1

问题出在这里：

if file == 'python_files.zip':
    print ('ZIP FILE STILL PRESENT')
    #os.remove('python_files.zip')
    if file == 'anti_vowel.py':
         print('EXTRACTED FILE IS PRESENT')
    else:
        print('EXTRACTED FILE IS MISSING')

如果file等于'python_files.zip'，那么它也不能等于'anti_vowel.py'而不更改其值，因此它始终位于else 1}}部分

简而言之，我认为您无法读取超出容器范围的压缩文件内容。首先，我几乎没有开始软件开发指导，也不了解任何事情，但是我确实了解您要完成的工作。同样，当我加载音乐软件程序FL Studio时，音频文件处于压缩状态（以zip文件压缩），DAW看到的是文件对象。拖动时，压缩文件图标将与之交互并触发响应。设置并在悬停时产生视觉变化（例如），但是当加载状态指示器完成时，音序器中没有轨道。我认为也许正在发生的事情是IDE无法看到压缩文件内容容器以及部分或全部元数据，但是看不到您定义的实际数据文本，因此无法生成预期的文件。我知道可以从某些想法（如VS代码）和某些扩展包中读取压缩文件。另外，正在使用什么终端工具？

文件extractall无法在python中工作
