Input undefined | python2.7

Question

I am making a simple program that repeats what I input. The current code is this:

print("Please enter your username.")
n = str(input(">> "))
print("Welcome, ",n)

However, when I run it and input, say, John, it would print the error: John is undefined, or something very similar to that. Any ideas why? Solutions?

Use raw_input() instead. Using input() requires the use of "" when you enter the name and want it to be interpreted as a string.

>>> n = input(">> ")
>> "john"
>>> print n
john

When using raw_input() you can do the following:

>>> n = raw_input(">> ")
>> john
>>> print n
john

input() interprets an unquoted string input as a variable, i.e you can do something like

>>> x = 5
>>> y = input()
>> x
>>> print y
5
