The list returned has all the values in the parameter list that are larger than the element immediately to their right, that is, larger than their right neighbor. If the parameter list is empty or there are no values larger than their right neighbor, then the function returns an empty list. Note that the last element in the list will never be included in the list returned since it does not have a right neighbor. The function should not change the parameter list in any way. Note that a correct solution to this problem must use an indexed loop That is, one that makes a call to the range() function to generate indices into the list which are used to solve the problem (Review lecture notes 8-1). A solution that does not use an indexed loop will not be accepted. Note in particular that you…arrow_forward
- Lottery number generator: Write a program that generates aseven-digit lottery number. The program should have a loopto generate seven random numbers, each in the range 0through 9 and assign each number to a list element.2. Write another loop to display the contents of the list.3. Tip: You will need to create/initialize your list before you canassign numbers to it.4. Use program 7-1 sales_list as an example. You will start witha seven-digit lottery number that contains all zeros. Then inyour loop, you will assign a random number instead ofgetting the data from the user.Turn in your program to the practice assignment link in coursecontent.arrow_forwardLargest Value. Create a program that uses a list to store input values, and outputs the largest value entered at its location in the list. The program shall accept input values until the user enters -1. And Next Movie Time. Create a program that shows the user when the next showing for a movie is. The program first reads the different showing times (only hours) in a 24-hour clock format (that is, 1PM is 13, 6PM is 18, etc.). The program then asks when a customer wants to go to the movies. The program replies with the time for the next showing. If the next showing matches the hour input by the customer, show the next showing after that. If the next showing is past the last one, the program shall output, “There are no more showings.”, Here is a sample execution: I am trying to use these programs as practice for practicing lists, strings and inputs.
