Exercise Solution Blocks in Chapter 1 Jupyter Notebook

[juanalbglz]

Hi! I've just started following your amazing book, Think Python, and I'm really enjoying it—thanks for making it accessible!

I noticed in the Chapter 1 Jupyter notebook that the code cells for solving the exercises are located far below the actual exercises. This makes it a bit inconvenient, as I find myself scrolling up and down constantly to read the exercise and then code the solution.

Improvement Suggestion:
Could each exercise be followed immediately by a blank code cell for writing the solution? This would encourage readers to engage with each exercise in place and make the learning flow smoother.

Thanks again for the great resource!
