Python has a set of built-in methods that you can use on lists/arrays. Add the elements of a list (or any iterable), to the end of the current list. Returns the index of the first element with the specified value. Note: Python does not have built-in support for Arrays, but Python Lists can be used instead. Until Python 3.5 the only disadvantage of using the array type was that you had to use dot instead of * to multiply (reduce) two tensors (scalar product, matrix vector multiplication etc.). Since Python 3.5 you can use the matrix multiplication @ operator. Given the above, we intend to deprecate matrix eventually. Docs.
