Learn the Bisection Method by Finding the Square Root of a Number - Step 2

Python
1

Hi all! :blush:

I’m trying to write a function to calculate square roots. The requirements are:

  • It should take square_target, tolerance = 1e-7, and max_iterations = 100 as parameters.
  • It should stop when the approximation is within the tolerance or when the max iterations are reached.

Here’s what I have so far:

def square_root_bisection(square_target, tolerance = 1e-7, max_iterations = 100):
    pass

Any tips or examples to help me complete this? Thanks in advance! :pray:

Hello @wolli

I have copied and pasted the same Code like yours and it passes the Test. To complete the function you will go trough small steps.

I’m struggling with the same issue ;(

i just did it!!
all you need to do is simply add “pass” after the function definition.
the 1’st function before the one you are declearing, which is the same one, idk why it’s auto duplicated,
i hope this was useful.

Hi @wolli , I will give it a try for you.
You can define the function using your params instead of pass.
You can run loops to max_iterations and should approach to the result using binary search. Plz let me know if you need any help. :slight_smile:
