[Tutor] Error Using exec to Run Module Files

[mesrod at juno.com]

I'm a rank beginner in Python.  Took advantage of the O'Reilly one-day sale of 'Learning Python' announced on the tutor, and starting to work my way through it.  When I tried out an example from pg57, on Using exec to Run Module Files, I get the following result:
>>> exec(open('script1.py').read())
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<string>", line 1

SyntaxError: invalid syntax
