Determine the terminal value of y using a while loop

Question

Rolling summation.

Determine the terminal value of y . While y is less than the threshold, add 0.01*(−2) to the old value of y .

y = 0.1 
threshold = .11

I tried this.

while  y < threshold:
    if True: 
        print(y+ 0.01*(y-y**2))
    else:
        break

Why did nothing run when i tried this?

Answer 1

If your intent is to start with y = 0.1 , and then continuously update y by adding the value of 0.01*(yy**2) to the current value of y until it equals or exceeds the value of threshold = 0.11 , the following code accomplishes this. If your intent is otherwise, please specify.

y = 0.1
threshold = .11

while y < threshold:
    y += 0.01*(y-y**2)

print(y)
