Python codes are required, one code per item:

$1.$ Implement a function which accepts as input a list of tuples and returns a new list oftuples, where each tuple includes the sum of the elements of the corresponding positions ofthe original tuples.

$2.$ Implement a function which accepts as input a tuple of integers and returns a new tuple whose every element is the product of all the elements of the original tuple, excluding the element of the current position $($e$.$g$.$ For $(2,3,4)$ the output will be $(12,8,6)).$

$3.$ Implement a function which accepts as input a list of tuples and returns a new list of tuples, arranged based on the $2$ nd element of the given tuple in descending order.

$4.$ Implement a function which accepts two tuples as input and returns a new tuple that includes all the common elements of the original tuples.

$5.$ Implement a program which combines two dictionaries by adding the individual values only when there are common keys.
