Learn the Bisection Method by Finding the Square Root of a Number - Step 17

Tell us what’s happening:

Hello, I am not sure what I have done wrong here? The error keeps saying I have to create an if statement which I have done, but not letting me pass the test?

``````def square_root_bisection(square_target, tolerance=1e-7, max_iterations=100):
if square_target < 0:
raise ValueError('Square root of negative number is not defined in real numbers')
if square_target == 1:
root = 1
print(f'The square root of {square_target} is 1')
elif square_target == 0:
root = 0
print(f'The square root of {square_target} is 0')

else:
low = 0
high = max(1, square_target)
root = None

for _ in range(max_iterations):
mid = (low + high) / 2
square_mid = mid**2

if abs(square_mid - square_target) < tolerance:
root = mid
break

elif square_mid < square_target:
low = mid
else:
high = mid

if root is None:

Outside the for loop,

Sounds like it should be outside the for loop, but still within the `else:`

Thanks so much that was it!
