Why does the input function HAVE to be inside the while loop?

Question

i = 0
y = 100
while i < 4:
x = input()
if x == "hit":
y = y + 10
i = i + 1
else:
y = y - 20
i = i + 1

print(y)

Answer 1

Because the code will ask you for 4 inputs. As you probably had learned, a loop is a convenient way to deal with repetitive tasks. Exactly like this where 4 inputs will be read in, which decide what changes should happen to <y> value (increased or decreased)

Without placing the input() in a loop, you'd be copy-pasting the code block manually, which is rather dull and boring.

Answer 2

Having the input inside the loop means that input is taken in every iteration, not just once.
According to this code, the value of i is increased in every iteration too. So the loop will execute exactly 4 times.
