5. (20 points) Asume that we have three types of classes in a gym that repeat every week. Whenever a student attends a class, we add their names to a list. If a student attends a class multiple weeks, we add their names multiple times, At the end of a month, the lists might look like these (your program should work for any combination of these lists): yoga_1ist = ['Anne', 'Any', 'Bob', 'Amy', 'Zach', 'Ali', 'David', 'Al1', 'Ayla', 'Bahar', 'Ayla'] pilates,list = ['Ayla', 'Amy', 'Bob', 'Any', 'Ali', 'David', 'Ali', 'Ayla', 'Eliz', 'Bahar', 'Ayla'] spin_1ist = ['Amy', 'Bob', 'Amy', 'Zach', 'Ali', 'David', 'Ali', 'Ayla', 'Eliz', 'Anne', "Ayla', 'Janess'] a) (7 pts) Write a program that finds and prints the total mamber of dasses Ayla has attended. (For the lists above, the answer should be 7.) b) (7 pts) Write a program that prints names of the students who attended all three claves at least once in a month. c) (6 pts) Write a program that prints names of the students who attended both spin and yoga chasses at least once, but did not attend pilates at all. Hint: For soune of the questions, couverting lists to sets might help you
