I have two lists, one of which consists of x coordinates and the other consists of y coordinates. x_coordinates = [1, 2, 3, 4, 5] y_coordinates = [1, 2, 3, 4, 5] For example, point 1 is (1,1) I want to calculate the covariance of the two lists and I have programmed a code, but I think it's somewhat unnecessarily long and messy. WebPython List provides different methods to add items to a list. 1. Using append () The append () method adds an item at the end of the list.
