用户交互

例:

name = input("Input your name:")

print(name)

结果:

input your name :hongwei
hongwei

 

PYTHON2.7里

name = input("Input your name :")

print(name)

结果：直接输入hongwei  会报错NameError:name'jack' is not defined

需要输入:"hongwei"  #如果不加引号会被当作变量处理。

改:

n = "hongwei"

name = input("Input your name:")

print(name)

结果：直接输入n

输出的结果为：

Input your name:n

hongwei
