python removes files with specified suffixes from zip (recommended)

import shutil
import zipfile
import os
from shutil import *
def UnZipFile(zip_src, dst_dir):# decompression function to decompress zip_src to dst_dir
  r = zipfile.is_zipfile(zip_src)
  if r:   
    fz = (zip_src, 'r')
    for file in ():
      (file, dst_dir)    
  else:
    print('This is not zip......')
def DelFileInZip(path,suffix):
  pathName=path[:('.')]
  pathName=()
  if not (pathName):
    (pathName,0o777)
  else:
    print pathName+' Already exist......'
  print("UnZip:"+path)
  UnZipFile(path,pathName)#Unpack the file to pathName,python3 can use shutil.unpack_archive(path, pathName, 'zip')
  for root,dirs,files in (pathName):# Traverse the pathName folder
    for f in files:
      fileName=(root,f)
      if((suffix)):#Find the file with the suffix suffix
        if (fileName):
          (fileName)# Delete the target file
          print('del:'+fileName)
        else:
          print fileName+" not file......"
  print('Zip:'+path)
  shutil.make_archive(pathName,'zip',pathName)# Compression
  (pathName)# Delete temporary files
  print('=======Finish!======')
  return ''
DelFileInZip('D:\\','log')
