Had been working on something else, came back to course, and am having trouble finding the lessons where it is covered.
Please give us an example (perhaps a screenshot) of how they use @. The one use of it that I can think of offhand is that it is a shorthand for dot product style matrix multiplication. In python and numpy, we have the following “overloaded” operators:
A*B is equivalent to np.multiply(A,B)
A@B is equivalent to np.dot(A,B)
