Consider this #Python code: x = 100 for i in range(10): x = i ** 2 print(x) What is printed? Answer: 81. Wait, isn't x local, inside of the loop? Shouldn't it be 100? Nope — indentation ≠ scope. Inside of a loop, without a function, you're still in the global scope. Questions?

The fact that the same indentation is used for blocks such as loops but also functions often confuses beginners

Just add “Do you think…” at the start and “…?” at the end
