python使用os模块的os.walk遍历文件夹示例

import os

if __name__ == ‘__main__‘:
    try:
    ‘‘‘traval and list all files and all dirs‘‘‘
    for root, dirs, files in os.walk(‘D:‘ + os.sep + ‘Python27‘):
        print ‘-------------------directory < ‘ + root + ‘ > --------------------------‘

        for d in dirs:
        print d
        for f in files:
        print f
    except OSError, e:
    print os.strerror(e.errno)
