文件extractall不能在Python中工作

-1

我想通過指定目錄名稱來提取文件。但我提取的目錄沒有出於某種原因提取的文件。輸出顯示zipfile已成功創建，但提取未成功完成。文件extractall不能在Python中工作

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')

OUTPUT： -

ZIP FILE STILL PRESENT

問題是在這裏：

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等於'python_files.zip'，那麼就不能也等於'anti_vowel.py'而不改變它的值，因此它總是在else部分

是的，你是對的。合併這些更改後，我仍然看不到目標目錄中的提取文件。如果文件== 'python_files.zip'：打印（ 'ZIP文件仍然存在'）如果文件== 'anti_vowel.py'：打印（ '提取的文件存在'）打印（'萃取後： - '，'\ n'，os.listdir（'C：\\ Users \\ aryan'）） – Ary

解壓後的文件應該出現在'C：\\ Users \\ aryan'中，但它不存在。 – Ary
