Code Cell UNQ\_C2: Unexpected error (TypeError(“‘NoneType’ object is not callable”)) occurred during function check. We expected function `sq_dist` to return type \<class ‘bool’\>. Please check that this function is defined properly.  
If you see many functions being marked as incorrect, try to trace back your steps & identify if there is an incorrect function that is being used in other steps.  
This dependency may be the cause of the errors.  
What can I do

Hello Lavanya,

What Tom is trying to ask you is if you have recalled all the codes or missed any of the None object which needs to recalled with the correct code.

Your error log tells you have recalled your function with incorrect steps or missed calling the points and/or centroids that would create new centroids.

So go back again to your UNQC2 and see if you have recalled your codes correctly.

if you still cannot find, then send notebook/code for UNQC2 via personal DM. Click on my name and then message.

Regards
