Python input 使用

Python 3.0 中使用"input" , Python 2.0 中使用"raw_input"
Python 3.5：

 #！C:\Program Files\Python35/bin
 # -*- conding:utf-8 -*-
 # author: Frank
 user_input = input("please input your name:") #input 函数的使用
 print("User input Msg:", user_input)

 # 显示结果
  >>>please input your name: Frank
  User input Msg:  Frank

Python 2.7:

 Python 2.7.12 (v2.7.12:d33e0cf91556, Jun 27 2016, 15:24:40) [MSC v.1500 64 bit (AMD64)] on win32
 Type "help", "copyright", "credits" or "license" for more information.
 >>> user_input = input("your name:") # For python2.7 , 这是错误的写法
your name:is
Traceback (most recent call last):
   File "<stdin>", line 1, in <module>
   File "<string>", line 1
     is
     ^
 SyntaxError: unexpected EOF while parsing
 >>> user_input = raw_input("your name:")  # For python 2.7 , raw_input 是正确的.
 your name: Frank
>>> print user_input
  Frank

在python3.0 中， input 默认接受的都是 string

eg: 下面的代码将出错

# -*- conding:utf-8 -*-
# author: Frank
name = input("please input your name:")
age = input("please input your age:")
job = input("please input your job:")

# 这里用了一个变量Msg，多行模式
Msg = '''
Information of user Frank:%s
------------------------
Name : %s
Age : %d
Job ：%s
------------End---------
''' %(name,name, age, job)
print(Msg)

结果出错：

please input your name: frank bian
please input your age:34
please input your job:it
Traceback (most recent call last):
  File "<encoding error>", line 16, in <module>
TypeError: %d format: a number is required, not str
