#coding=gbk'''os.walk(dir) 是三列的数组'''import osdir = os.getcwd()for cons in os.walk(dir):    print cons#根目录、所有目录、目录下的文件for root, dirs, files in os.walk(dir):    for name in files:        print os.path.join(root, name)

file.read()  读全部
file.read(N) N个字节
file.readline() 
file.readlines() return a list

file.write(...)

file.seek(0)
file.next()
file.close()
