批量压缩和解压

python3.6

#coding=utf-8
import os,os.path
import zipfile

    for root, dirs, files in os.walk(dirname):
        return root,files

  filelist = []   
  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):]
    #print arcname
    zf.write(tar,arcname)
  zf.close()
def unzip_file(zipfilename, unziptodir):
  if not os.path.exists(unziptodir): os.mkdir(unziptodir, 0o777)
  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,0o777)
      outfile = open(ext_filename, 'wb')
      outfile.write(zfobj.read(name))
      outfile.close()
      
if __name__ == '__main__':
    dirname = r'E:/lsl/imageSpider/imageSpider/images'
    root,_ = get_files(dirname)
    
    for i in range(1,31128,500): #31128
        print(i)
        files=[]
        k=i+499 if i+499<31128 else 31128
        for j in range(i,i+500):
            if j > 31128:
                break
            files.append(r'__ ('+str(j)+r').jpg')
        #print(files)
        zip_dir(dirname,root,files,r'd:/images/images'+str(i)+"-"+str(k)+r'.zip')
    #unzip_file(r'E:/zip1-500.zip',r'E:/zip1-500')

文件夹中图片有30000多张，一次压缩还是很大。所以先统一命名图片，然后搞500张压一个包。
图片命名如下：
