USING PYTHON PLEASE
Transcribed Image Text:Write the following two functions and submit the program file in which you write them. Use appropriate lists and
dictionary methods. Test the functions before submitting.
1. Write a function addLists that takes two lists of numbers (assumed to be of equal length) and returns another list
which has each element as the sum of the corresponding elements of the two lists. For example, if the two lists are
[2,3,4] and [3,1,1] then the returned list should be [5,4,5]. The function should check that the two lists are of equal
length before proceeding otherwise should print a message if they are not equal.
2. Write a function makeDict that takes a list as an argument and returns a dictionary such that its keys are the
elements of the list and the values are the number of times the element is present. For example, if the list is [10, 5, 10,
4, 5, 10] then the returned dictionary should be {10:3, 4:1, 5:2} (the order does not matter).
