slide 2-44: squares() is not called

[arturtamborski]

Thank you very very much for this material. It's amazing! I'm super grateful for it.

I think I spotted a small error in the code on slide 2-44:

-for n in squares:
+for n in squares([1, 2, 3, 4, 5]):

I think the squares should be called to be effective.

Thank you again for sharing your knowledge.

Good catch! I've corrected the source material. Will appear in the PDF the next time I update it.
