def DiagnolSum(self, array1): self.array1 = array1 print(array1) for i in range(len(array1)): pass
This is a method i have made by making a class called Array and when i run the above code it gives me an error of object of Array has no len() function, can somebody help me with it?? Actually i am performing the sum of diagnol of a matrix but just for printing the matrix in list form, i have to run this code.
Furthermore, I am using it without numpy!!
