python压缩新文件到已有ZIP文件 python怎样压缩新文件到已有ZIP文件

from zipfile import ZipFile
from os import listdir
from os.path import isfile, isdir, join

def addFileIntoZipfile(srcDir, fp):
 #遍历该文件夹中所有文件
 for subpath in listdir(srcDir):
 subpath = join(srcDir, subpath)
 if isfile(subpath):
  #如果是文件就直接压缩到ZIP文件
  fp.write(subpath)
 elif isdir(subpath):
  #如果是子文件夹就先写入子文件夹名
  #然后再递归调用函数
  #把所有文件都压缩进入ZIP文件
  fp.write(subpath)
  addFileIntoZipfile(subpath, fp)

def zipCompress(srcDir, desZipfile):
 with ZipFile(desZipfile, mode='a') as fp:
 addFileIntoZipfile(srcDir, fp)

#测试函数功能
paths = [r'C:\python34\Scripts', r'C:\python34\Dlls', r'c:\eclipse']
for path in paths:
 zipCompress(path, 'test.zip')
