Please help me understand.

Question

#example 1

counter = 0
while counter < 8:
counter += 10
print("#")

#example 2

counter = 0
while counter < 8:
print("#")
counter += 10

Why does example 1 and 2 have the same output. Shouldn’t there be no # printed for example 1. Because the first loop add 10 before meeting the condition. However example 2 makes more sense.

Answer 1

The condition is checked before an iteration. The fact that during the iteration the value changes so the condition is no longer fulfilled plays no role for that iteration. The condition is not checked during an iteration.
