python如何压缩新文件到已有ZIP文件

from zipfile import ZipFilefrom os import listdirfrom os.path import isfile, isdir, joindef 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')
