python编程input与raw_input

运行环境Python2.7.6

input和raw_input作为输入语句，其不同之处在于：

1、当输入的内容为字符串时，

用input语句必须加上“”号，否则报错，而用raw_input不用

<span style="font-size:14px;">>>> input("who are you:")
who are you:jack

Traceback (most recent call last):
  File "<pyshell#0>", line 1, in <module>
    input("who are you:")
  File "<string>", line 1, in <module>
NameError: name 'jack' is not defined
>>> input("who are you:")
who are you:"jack"
'jack'
>>> raw_input("who are you:")
who are you:jack
'jack'
>>> raw_input("who are you:")
who are you:"jack"
'"jack"'
>>> </span>

2、当输入内容为int型内容时，只能用input语句

<span style="font-size:14px;">>>> s = raw_input("who are you:")
who are you:123
>>> s
'123'
>>> type(s)
<type 'str'>
>>> s = input("who are you:")
who are you:12
>>> s
12
>>> type(12)
<type 'int'></span>
