PROGRAM A: APROGRAM.py This program should use a main function and two other functions named playlist and savelist as follows: The main function: The main function should create an empty list and then use a loop to add ten integers to the list, each in the range from 10-90. These integers will represent angles measured in degrees. main should then call playlist and savelist, in that order. Both of these functions take the list as a sole argument. The playlist function: playlist should use a loop to display the elements of the list, all on one line separated by a single space. playlist should also determine and print the number and sum of the even numbers and the number and sum of the odd numbers. The savelist function: save list should sort the list and write each element to a text file named AB.txt, each element on its own line. PROGRAM B: BPROGRAM.py This program should read the angles from AB.txt and generate a table showing the trigonometric ratios sine, cosine, and tangent of the angles. The ratios should be displayed in formatted columns accurate to 5 decimal places as shown in the sample output below. SAMPLE OUTPUT: Here are the angles in degrees: 23 85 31 55 42 85 72 33 39 20 3 even angles total to 134 7 odd angles total to 351 List of angles was written to file. End of program A.
