【学习笔记】python2和python3的input()

python2中的input()只接受变量作为传入值，非变量内容会报错。

 >>> user=input("Enter your name:")
 Enter your name:Kaito
 Traceback (most recent call last):
   File "<stdin>", line 1, in <module>
   File "<string>", line 1, in <module>
 NameError: name 'Kaito' is not defined
 >>>
 >>> name="Kaito"
 >>> user=input("Enter your name:")
 Enter your name:name
 >>> print(user)
 Kaito

所以在python2中，我们用raw_input()来代替input()的功能来键入内容。

 >>> user=raw_input("Enter your name:")
 Enter your name:Kaito
 >>> print(user)
 Kaito

而python3的input()可以说是取代了python2的raw_input()。

 >>> user=input("Enter your name:")
 Enter your name:Kaito
 >>> print(user)
 Kaito
