Focus on: Basic list operations, methods, use of functions, and good programming style Part 1. Write a program in python that does the following: 1. Create a list of length N where N is a randomly selected integer between 10 and 20 and whose elements are randomly selected integers between 0 and 19. 2. Print out the list. 3. Create a copy of the list. Sort the copy into decreasing order and print it. 4. Report the distinct elements in the list Before continuing with the next two parts, add a function user_input(lo, hi) to your program. It should ask the user for an integer between lo and hi and return the value. Use appropriate error handling and input validation. (You should already have one of these from back in Module 05) Part 2. Write a function named how_many(a_list, a_num) that that expects a list of numbers and a number as arguments. It returns how many times the number is found in the list. If the number is not in the list, return 0. For example how_many( [12, 15, 16, 4, 10, 3, 5, 7, 9, 15], 15 ) returns 2 And how_many( [12, 15, 16, 4, 10, 3, 5, 7, 9, 15], 11 ) returns 0 Ask the user for an integer between 0 and 19. If the number is in the list, report how many times it occurs. Part 3. Write a function named find_bigger(a_list, a_num) that expects as arguments a list of numbers and a number. It should return a new list consisting of all the numbers in the list that are greater than the number. For example find_bigger( [12, 15, 16, 4, 10, 3, 5, 7, 9, 15], 11 ) returns [12, 15, 16, 15] And find_bigger( [12, 15, 16, 4, 10, 3, 5, 7, 9, 15], 15 ) returns [16] Ask the user for an integer between 0 and 19 and then report how many of the items in the list are greater than that number.
Types of Linked List
A sequence of data elements connected through links is called a linked list (LL). The elements of a linked list are nodes containing data and a reference to the next node in the list. In a linked list, the elements are stored in a non-contiguous manner and the linear order in maintained by means of a pointer associated with each node in the list which is used to point to the subsequent node in the list.
Linked List
When a set of items is organized sequentially, it is termed as list. Linked list is a list whose order is given by links from one item to the next. It contains a link to the structure containing the next item so we can say that it is a completely different way to represent a list. In linked list, each structure of the list is known as node and it consists of two fields (one for containing the item and other one is for containing the next item address).

how_many( [12, 15, 16, 4, 10, 3, 5, 7, 9, 15], 15 )
returns 2
And how_many( [12, 15, 16, 4, 10, 3, 5, 7, 9, 15], 11 )
returns 0
Ask the user for an integer between 0 and 19. If the number is in the list, report how many times it occurs.
Part 3. Write a function named find_bigger(a_list, a_num) that expects as arguments a list of numbers and a number. It should return a new list consisting of all the numbers in the list that are greater than the number. For example
find_bigger( [12, 15, 16, 4, 10, 3, 5, 7, 9, 15], 11 )
returns [12, 15, 16, 15]
And find_bigger( [12, 15, 16, 4, 10, 3, 5, 7, 9, 15], 15 )
returns [16]
Ask the user for an integer between 0 and 19 and then report how many of the items in the list are greater than that number.
