[Rehan11]

I am newbie here. I don't have knowledge of python program. after some reading I tried to write one program I just want to write simple program that will take input name from user and print the name on screen.

I have this program. when I enter my name I get error

>>> person = input('Enter your name: ')
print('Hello', person)
Enter your name: rehan

Traceback (most recent call last):
  File "<pyshell#0>", line 1, in <module>
    person = input('Enter your name: ')
  File "<string>", line 1, in <module>
NameError: name 'rehan' is not defined
