Newbie help with simple script written for v3.3 and used on vs2.7, please?

[PaulMorrey]

Hi
Im a complete newbie to any sort of programming so sorry if this is a stupid question - working my way through the python for absolute beginers on you tube and Im on Video2. Have got python running from cmd and using notepad++ for editor.  Code reads    

print("hello world")     
myName = input("what is your name?")     
print(myName)

above runs fine outputting

Output:
hello world
what is your name?

Video shows typing your name after the ?  (no space)  pressing enter key and then name should print  however I get an error message basically saying Name error Name Paul is not defined. 
I think video uses v3.3 and Im on 2.7 dont know if that makes a difference but any help welcome.  Thanks for reading.
Thanks
Paul
