python学习笔记8

主要讲了python的输入和输出
python通过[python2.x]raw_input和[python3.x]input来实现输入输出。
input可以加参数，表示为提示符，返回值为你的输入。

比如:

age = input("How old are you?")
print ("your age is %s", age)

How old are you?12

your age is %s 12

print可以通过end参数去除输出末尾的回车，换上end="??"中赋的末尾符号
比如：

print ("How old are you?", end=": ")
age = input();
print ("your age is %s", age)

How old are you?: 23

your age is %s 23
