002_009 Python 从Zip中读取数据 直接检查一个zip格式的归档文件部分或所有文件而且不用解压

代码如下：

#encoding=utf-8

print '中国'

#直接检查一个zip格式的归档文件部分或所有文件而且不用解压

import zipfile

zp = zipfile.ZipFile(r'D:\program files\ROMasterLab\Driver.zip','r')

for filename in zp.namelist():
print 'File:',filename
bytes = zp.read(filename, None)
print 'has',len(bytes),'bytes'

#创建ZipFile
import zipfile,tempfile,os,sys

filename = r'd:\1237.zip'
z = zipfile.ZipFile(filename,'w')
z.writestr('hello.py', 'def f(): return "hello world from"+__file__\n')
z.close()
sys.path.insert(0, filename)
import hello
print hello.f()
print sys.path
os.unlink(filename)

打印结果如下：
