笨办法学Python习题14 提示和传递

这个习题只要是raw_input与参数变量的结合使用！

前面的西体重raw_input（）内可以写一些“XXX”提问的内容。那么raw_input（）括号内可以填写替他的内容吗？

先上代码：

from sys import argvscript, user_name = argvprompt = '>'print "Hi %s, I'm the %s script."%(user_name,script)print"I'd like ask you a few questions."print "Do you like me, %s?" % user_namelikes = raw_input(prompt)print"Where do you live, %s?" %user_namelives = raw_input(prompt)print"What kind of computer do you have?"computer = raw_input(prompt)print"""Alright,so you said %r about liking me.you live in %r .Not sure where that is.And you have a %r computer .Nice."""%(likes,lives,computer)

运行结果如下：

Hi simengred, I'm the ex14.py script.I'd like ask you a few questions.Do you like me, simengred?>yesWhere do you live, simengred?>shenzhenWhat kind of computer do you have?>macbookAlright,so you said 'yes' about liking me.you live in 'shenzhen' .Not sure where that is.And you have a 'macbook' computer .Nice.

1，从代码中可知raw_input(),括号中也可以填写变量，变量的内容为“>”在运行程序时，>起到一个提示输入的作用。

2，代码的参数变量argv部分，算是对习题13的复习。

从terminal中输入的参数ex14.py 和simengred传递给argv.

再有argv解包将ex14.py赋值给script，simengred赋值给user_name

再通过格式化控制符，将这些值“镶嵌”到句子中。
