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

Python 3.5：

1 #！C:\Program Files\Python35/bin

2 #-*- conding:utf-8 -*-

3 #author: Frank

4 user_input = input("please input your name:") #input 函數的使用

5 print("User input Msg:", user_input)6

7 #顯示結果

8 >>>please input your name: Frank9 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 , 這是錯誤的寫法

your name:is

Traceback (most recent call last):

File "", line 1, in

File "", line 1

is

^

SyntaxError: unexpected EOF while parsing

>>> user_input = raw_input("your name:") # For python 2.7 , raw_input 是正確的.

your name: Frank

>>> print user_input

Frank

在python3.0 中， input 默認接受的都是 string

eg: 下面的代碼將出錯

# -*- conding:utf-8 -*-

# author: Frank

name = input("please input your name:")

age = input("please input your age:")

job = input("please input your job:")

# 這里用了一個變量Msg，多行模式

Msg = '''

Information of user Frank:%s

------------------------

Name : %s

Age : %d

Job ：%s

------------End---------

''' %(name,name, age, job)

print(Msg)

結果出錯：

please input your name: frank bian

please input your age:34

please input your job:it

Traceback (most recent call last):

File "", line 16, in

TypeError: %d format: a number is required, not str
