Max Function

Statistical function is of many categories. One of them is a MAX function. The MAX function returns the largest value from the list of arguments passed to it. MAX function always ignores the empty cells when performing the calculation.

Power Function

A power function is a type of single-term function. Its definition states that it is a variable containing a base value raised to a constant value acting as an exponent. This variable may also have a coefficient. For instance, the area of a circle can be given as:

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…

check_game_over(): as the name suggests, this function should check to see if the game is over (if one side has no stones left in all of its pockets). It takes as an argument the game board and should return True if the game is over and False otherwise.
*Coding language is Python Write a program that opens the productsales.txt file and reads the sales into a list. The program should output the following information, in this order: The total of all sales in the list The average of all sales in the list The lowest sale in the list The highest sale in the list NOTE: Your program should include at least one user-defined function, in addition to the main function. 4147 1594 2235 8433 10000 129 5555 7030 9764 7465 1111 4444 8954 2243 2895 1436 4978 5486 1436 9846 4789 8456 2497 2280 6375
6. sum_highest_five This function takes a list of numbers, finds the five largest numbers in the list, and returns their sum. If the list of numbers contains fewer than five elements, raise a ValueError with whatever error message you like. Sample calls should look like: >>> sum_highest_five([10, 10, 10, 10, 10, 5, -17, 2, 3.1])50>>> sum_highest_five([5])Traceback (most recent call last): File "/usr/lib/python3.8/idlelib/run.py", line 559, in runcode exec(code, self.locals) File "<pyshell#44>", line 1, in <module> File "/homework/final.py", line 102, in sum_highest_five raise ValueError("need at least 5 numbers")ValueError: need at least 5 numbers
my_round(number, integer): Based on the built-in round(...) function. Takes an integer or float and returns a rounded float value that is the number rounded to the second argument's decimal place. First argument can be any float or integer. Second argument must be an integer. Examples: my_round(1234.5678, 2) and round(1234.5678, 2) should return 1234.57. my_round(1234.5678, -2) and round(1234.5678, -2) should return 1200.0.
In Python, grades_dict = {'Wally': [87,96,70], 'Eva': [100,87,90], 'Sam': [94,77,90], 'Katie': [100,81,82], 'Bob': [83, 65, 85]} Ask user to enter the names of the rows, i.e., indices. You can use: len(grades) to get the number of rows of the DataFrame. In addition, using the sort_index() method, ask user whether they wish to sort by rows or by columns and whether to sort in ascending or descending order (do not use any if-else statements)
