Error while using input() function

 Error while using input() function :---

#!/usr/bin/python
print ('Hello! What is your name?')
myName = input()

 Output:-
 Hello world!
What is your name?
Aman
Traceback (most recent call last):
File "C:/Python24/game.py", line 3, in <module>
myName = input()
File "<string>", line 1, in <module>
NameError: name 'Aman' is not defined


...then this means you are running the program with Python 2, instead of Python 3.

The input() and raw_input() Functions
In Python 2, the function to get input from the keyboard is raw_input(). In Python 3, the input() function does this. You can simply rename the function wherever it appears in your code.
>>> # Python 2
>>> name = raw_input()
>>> # Python 3
>>> name = input()

#!/usr/bin/python
print ('Hello! What is your name?')
myName = raw_input()
