python替换jar包（zip）中的文件

import zipfile
import os
import shutil
import time

filename = "C:\Users\ssb\Desktop\yufabu_tmp\ibt-1.1.0-REALEASE.jar"  # 待解压文件，zip解压同样适用于jar！！！划重点
path2 = "C:\Users\ssb\Desktop\yufabu_tmp\ibt-1.1.0-REALEASE"  # 解压路径

fz = zipfile.ZipFile(filename, 'r')
for file in fz.namelist():
  fz.extract(file, path2)

# 删除删除main.ftl文件
delete_filename = 'C:\Users\ssb\Desktop\yufabu_tmp\ibt-1.1.0-REALEASE\\freemarker\main.ftl'
if os.path.exists(delete_filename):
  os.remove(delete_filename)
# time.sleep(60)
# shutil.copy(文件的路径，另一个目录);拷贝main.ftl到准备压缩的目录下
shutil.copy('C:\Users\ssb\Desktop\yufabu_tmp\main.ftl', 'C:\Users\ssb\Desktop\yufabu_tmp\ibt-1.1.0-REALEASE\\freemarker\\')
print time.ctime(os.stat('C:\Users\ssb\Desktop\yufabu_tmp\ibt-1.1.0-REALEASE\\freemarker\main.ftl').st_mtime)

# 压缩回去
startdir = "C:\Users\ssb\Desktop\yufabu_tmp\ibt-1.1.0-REALEASE"  # 要压缩的文件夹路径
file_news = startdir+'.jar'  # 压缩后文件夹的名字
z = zipfile.ZipFile(file_news, 'w', zipfile.ZIP_DEFLATED)  # 参数一：文件夹名
for dirpath, dirnames, filenames in os.walk(startdir):  # os.walk 遍历目录
    fpath = dirpath.replace(startdir, '')   # 这一句很重要，不replace的话，就从根目录开始复制
    fpath = fpath and fpath + os.sep or ''  # os.sep路径分隔符
    for filename in filenames:
        z.write(os.path.join(dirpath, filename), fpath+filename)
        # os.path.join()函数用于路径拼接文件路径。
        # os.path.split(path)把path分为目录和文件两个部分，以列表返回
        print '压缩成功'

z.close()
