Python：How to convert .7z to .rar or .zip？

Question

如何使用Python将.7z文件转换为.rar或.zip文件？

Answer 1

您可以分两步进行。首先，解压缩.7z文件，然后将内容压缩到zip文件。

解压缩.7z压缩文件

from lib7zip import Archive, formats 

with Archive('filename.7z') as archive: 
    # extract all items to the directory 
    # directory will be created if it doesn't exist 
    archive.extract('directory')

压缩到压缩文件

#!/usr/bin/env python 
import os 
import zipfile 

def zipdir(path, ziph): 
    # ziph is zipfile handle 
    for root, dirs, files in os.walk(path): 
     for file in files: 
      ziph.write(os.path.join(root, file)) 

if __name__ == '__main__': 
    zipf = zipfile.ZipFile('file.zip', 'w', zipfile.ZIP_DEFLATED) 
    zipdir('tmp/', zipf) 
    zipf.close()
