- Sum of two squares def sum_of_two_squares(n): Some positive integers can be expressed as a sum of two squares of some positive integers greater than zero. For example, 74 = 49 + 25 = 7^2 + 5^2. This function should find and return a tuple of two positive integers whose squares together add up to n, or return None if the parameter n cannot be broken into a sum of two squares.To facilitate the automated testing, the returned tuple must present the larger of its two numbers first. Furthermore, if some integer can be broken down to a sum of squares in several ways, return the breakdown that maximizes the larger number. For example, the number 85 allows two such representations 7^2 + 6^2 and 9^2 + 2^2 , of which this function must return (9, 2).The technique of two approaching indices that start from the beginning and end of a sequence, respectively, and approach each other until they meet somewhere is directly applicable to this problem. In this problem, these indices crawl towards each…The function below does not work as expected: If sales is a negative number is returns 3 instead of returning 0.

Create the add func() function, which accepts two arguments. The function should use the + operator to add the two arguments and then return the result. For instance, 3 should be returned if the arguments' input values are 1 and 2. Likewise, "good day" should be returned if the input arguments are "good" and "day." # TODO 6.1 print(f"add_func output for 1 + 2: {add_func(1, 2)}") print(f"add_func output for good + day: {add_func('good',' day')}") todo_check([ (add_func(1,2) == 3,'add_func() did not return 3 when using input values 1 and 2.'), (add_func('good',' day') == "good day",'add_func() did not return "good day" when using input values "good" and " day"') ])

This function will receive an assignment then a grade should be calculated using the following formula: grade = 1 - (Student's current energy X Assignment difficulty level). The min grade a student may receive is 0% (0) After the grade is calculated the student's energy should be decreased by percentage difficulty. Example if the student has 80% (.8) energy and the assignment is a difficultly level .2 there final energy should be 64% (.64) = .8 - (.8 * .2). The min energy a student may have is 0% (0) Finally the grade calculated should be stored internally with in this class so it can be retrieved later.
