【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。

 1 >>> user=input("Enter your name:")
 2 Enter your name:Kaito
 3 Traceback (most recent call last):
 4   File "<stdin>", line 1, in <module>
 5   File "<string>", line 1, in <module>
 6 NameError: name ‘Kaito‘ is not defined
 7 >>>
 8 >>> name="Kaito"
 9 >>> user=input("Enter your name:")
10 Enter your name:name
11 >>> print(user)
12 Kaito

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

1 >>> user=raw_input("Enter your name:")
2 Enter your name:Kaito
3 >>> print(user)
4 Kaito

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

1 >>> user=input("Enter your name:")
2 Enter your name:Kaito
3 >>> print(user)
4 Kaito
