I'm pretty sure this is an eclipse console issue.  Since you have it,
try stepping through the program in the debugger and inspect the
answer variable after raw_input returns.  On my setup, at that point
answer is 'no\r', but raw_input() is supposed to strip line endings.
I'm guessing the console supplied 'no\r\n' and only the \n was
stripped.  Could be that python does not recognize that eclipse's
console uses CRLF line endings.

As a workaround you can do raw_input().strip().

You might check the eclipse issue tracker to see if this a known
issue.
