# Learn the Bisection Method by Finding the Square Root of a Number - Step 18

``````            print(f"Failed to converge within {max_iterations} iterations.")
else:
root is not None
print(f'The square root of {square_target} is approximately {root}')`````````

Learning to describe problems is hard, but it is an important part of learning how to code.

Also, the more you say, the more we can help!

Sorry I tried posting but it just posted the code not the description. I am trying to figure out what i need to do to pass the code I tried indenting and moving things around but doesnt seem to pass still?

I donâ€™t know what the code is supposed to do, as you deleted the link to the step

### Tell us whatâ€™s happening:

Tried to move code around but still encountering problem somewhere, I think indentation but not sure. Code wont pass.

``````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

The response I keep getting is â€śyou should create an else clauseâ€ť?

`else:` handles all other cases, so it doesnâ€™t take a condition. But you have a random condition on the next line

Not understanding whay you mean by random condition the request is to say is not None?

I just got what you meant by random condition got rid of it now it passes.
