【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
