DO NOT use numpy at any point. 1A) Give the class an __init__ method Make sure that the variable array is a valid input. This means you should a) Make sure that array is a list of lists. and b) Make sure that each of the inner lists has the same length. You do not need to check for anything else. Rise the appropriate error(s) if these conditions are not met. It is up…
