Newbie question - input doesn't work in Emacs python-mode

[K. Fleming]

I just started fooling around with Python and so far have enjoyed it
immensely.  However, I came across a problem when using Emacss
python-mode.  The following line

answer = input("Will this work?")

will not work.  It generates the error

EOFError: EOF when reading a line

It works fine when I try to run it in IDLE however.  Can anyone help
me?  Thanks to all who respond.
