In the first iteration, i is set equal to 10. Then, before starting the
second iteration, i is incremented to 11; then the loop condition is
checked and results in false. So the loop terminates after the first
iteration.
So, the point is that in C you can influence the loop's behavior by
modifying the loop variable, while you cannot do that in Python (at
least not in a for-loop).
In other words, the point is that you can't translate loops literally
from C to Python. Which is nothing new, and I fail to see how that is
supposed to be a disadvantage.
