2.9 从zip文件中读取数据

可以通过Python标准库提供的zipfile模块访问zip压缩文件

>>> import zipfile
>>> z = zipfile.ZipFile('test.zip','r')
>>> for filename in z.namelist():
    print 'File:', filename

File: wex.txt
File: 1.txt
File: a.txt

2.16 遍历目录树

使用os.walk可以便利目录树

>>> for root, dirs, files in os.walk("E:\PythonCookbook\\"):
    print root,dirs,files
    
E:\PythonCookbook\ ['CHA2', 'CHA3'] []
E:\PythonCookbook\CHA2 [] ['abinfile', 'thefile.txt']
E:\PythonCookbook\CHA3 [] ['1.py', 'countWorkdays.py', 'findlastFriday.PY', 'test.zip']
