I only need help with the second problem just posting the first one cause that's what it referring to. The language is python.

Exercise: (2 points) The Taylor series approximation to pi is given by the formula 4* (1/1 - 1/3 + 1/5 - 1/7 + 1/9 - 1/11 ...). In the following code cell, create a class with an _init_ and an _iter_function, similar to the above, that, when invoked for the kth time, returns 4 times the sum of the first k values in this sequence, along with examples that demonstrate its operation. Exercise: (2 points) In the following code cell, repeat the Taylor series example, but with a class with an init ,an_iter__, and a __next__ function, similar to the above. #
