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: Frank 9 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 "<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 "<encoding error>", line 16, in <module>
TypeError: %d format: a number is required, not str
