The numpy.array function is used to create a NumPy array. Here we just have to pass in a list of lists, it will automatically generate a NumPy array with the same number of rows and columns. Because for easy computation, we want all the elements in the array to be float elements, so, we’ll leave off the header row and column, which contains strings. This is the limitations of NumPy. As in ...
