Compilation error when submitted (Week1-Housing Prices)

[laksheenmendis]

When I run the code in Jupyter Notebook, I'm getting a prediction of 4.008... But when submitted it shows the below error in grader's output..

Can't compile the student's code. invalid syntax (student_solution.py, line 22)

I'm clueless.. Can you please look into it..

When I completed this exercise the other day, I used 10 examples. For example,

xs = 1.0 up to and including 10.0 ys = 1.0 up to and including 5.5. For example, 1.0, 1.5, and so on.

The predication should be close to 4.0 but not exactly 4.0. Finally, I learned through trial and error to do the following to create a good feeback loop:

1. Run all cells

2. Check the results

3. Save the Notebook

%%javascript
<!-- Save the notebook -->
IPython.notebook.save_checkpoint();

4. Submit the Notebook

5. In another window, refresh the submission page.
