[Python知识库]python_zip压缩和解压缩

代码：

def zip_dir(dirname,zipfilename):
  filelist = []
  if os.path.isfile(dirname):
    filelist.append(dirname)
  else :
    for root, dirs, files in os.walk(dirname):
      for name in files:
        filelist.append(os.path.join(root, name))
  zf = zipfile.ZipFile(zipfilename, "w", zipfile.zlib.DEFLATED)
  for tar in filelist:
    arcname = tar[len(dirname):]
    zf.write(tar,arcname)
  zf.close()

def unzip_file(zipfilename, unziptodir):
  if not os.path.exists(unziptodir): os.mkdir(unziptodir)
  zfobj = zipfile.ZipFile(zipfilename)
  for name in zfobj.namelist():
    name = name.replace('\\','/')
    if name.endswith('/'):
      os.mkdir(os.path.join(unziptodir, name))
    else:
      ext_filename = os.path.join(unziptodir, name)
      ext_dir= os.path.dirname(ext_filename)
      if not os.path.exists(ext_dir) : os.mkdir(ext_dir)
      outfile = open(ext_filename, 'wb')
      outfile.write(zfobj.read(name))
      outfile.close()

使用-压缩：

if __name__ == '__main__':
    zip_dir(r'E:/temp077/target_dir',r'E:/temp055/temp.zip')
    # unzip_file(r'E:/temp077/temp.zip',r'E:/temp066')
    print('---------------------- ending file_tools.py')
    pass

?使用-解压缩：

if __name__ == '__main__':
    # zip_dir(r'E:/temp077/target_dir',r'E:/temp055/temp.zip')
    unzip_file(r'E:/temp055/temp.zip',r'E:/temp066')
    print('---------------------- ending file_tools.py')
    pass

注意：如果压缩包中的文件夹为空，解压缩后不会把该文件夹解压出来?
