On Problem Set 2 Question 1, I can't get the inter active mode to print out the function. If I input something like: poly = (0.0, 0.0, 5.0, 9.3, 7.0) x = -13 print evaluate_poly(poly, x) 180339.9 But instead it says something like Traceback (most recent call last): File "", line 1, in print evaluate_poly(poly, x) NameError: name 'evaluate_poly' is not defined Not sure what I'm doing wrong, any thoughts? Its probably something ridiculously simple!

Assuming that you posted the entire session, either evaluate_poly() will need to be typed in before those three lines, or it will need to imported from a file:
from whateverFile import evaluate_poly

Ok, well that is good to know.  Python is still a little weird to me with this whole interactive mode.  I wasn't importing or typing in the code for the evaluate_ploy().  Once I did that it worked like a charm!  Thanks!

During testing/debugging, trying something new, the interactive is great.  It's actually a shell environment, separate from writing a file and then executing it.
