python编程问题！ 有一个txt文件，每一行有两个数据，之间用制表符隔开，怎么实现只读每一行的

#!/usr/bin/env python# coding: utf-8## filename: baidu_wordpyimport repatt = recompile(r"^[a-z]{6,}$")def wordinput(): """input a word word length at least 6, no space, no digit and no symbol """ while 1: word = raw_input("Input a word: ") if pattmatch(word): return worddef specialshow(word): """prints the first three characters, followed by three periods（), and then the last three characters """ print "%s%s" % (word[:3], word[-3:])def main(): specialshow(wordinput())if __name__ == "__main__": main()
