#82514 — How to use the .isalpha() function correctly

Here a very small program that I wrote for Codecademy. When I finished, Codecademy acted like it was correct, but testing of this code revealed otherwise.
--------------------------------------------------
print 'Welcome to the Pig Latin Translator!'

# Start coding here!
raw_input("Enter a word:")
original = str(raw_input)
if len(original) > 0 and original.isalpha():
    print original
else:
    print "empty"
--------------------------------------------------
No matter what I type in, the result is "empty." What do I need to do in order for it to accept words?

That’s not where the error is, actually.  You are:

1. taking input with "Enter a word: " and NOT SAVING IT
2. setting original to a string representation of the function
`raw_input`, which is something like

>>> str(raw_input)
'<built-in function raw_input>'

The correct way to do this is:

original = raw_input("Enter a word: ")

as raw_input already outputs a string.

Thanks very much. I'm not sure how I missed that, since I've used the exact same method you mentioned before. You've been very helpful.
