An addendum to previous comments solving the issue.  In 3.8.0b1, you 
would see the caret at the beginning of the word, rather than at the end.

This gives a better hint that the error is due to something before the 
'b', or rather that the parser was expecting something other than a 
letter (beginning of name character).  One should therefore imagine that 
there was no preceeding \n and that the initial character, in this case, 
was at the end of the previous line.  The error here is basically the 
same as

 >>> b b
   File "<stdin>", line 1
     b b
       ^
SyntaxError: invalid syntax
