Python input 使用

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 函数的使用 5 print("User input Msg:", user_input) 6 7 # 显示结果 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 , 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: Frankname = 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 : %sAge : %dJob ：%s------------End---------''' %(name,name, age, job)print(Msg)

 结果出错：

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