Python while loops

Question

x = int(input("Type in a number"))
while x > 0:
y = x
while y > 0:
y -= 1
print(y)
x -= 1
print("stop")

After I input 3, the output is:
2
1
0
1
0
0
stop

I understand where 2, 1, 0 come from, but what's happening afterwards is unclear to me.
Could you explain, please?

Answer 1

It's because the while y > 0 is executed three time. After the first one (2, 1, 0)

x = 2
x > 0 true
y = 2
y > 0 true
y -= 1 -> y = 1
print(y) -> 1
y -= 1 -> y = 0
print(y) -> 0

After that
x = 1
x > 0 true
y = 1
y > 0 true
y -= 1 -> y = 0
print(y) -> 0
x -= 1 -> x = 0
x > 0 false
print("stop")

Thanks, bruh. Have a nice day.

Answer 3

It's really all clear now. Great thanks.
