Module 07 Graded Assignment
Basic list operations, methods, use of functions, and good programming style
Part 1. Write a program 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
returns
how_many( [12, 15, 16, 4, 10, 3, 5, 7, 9, 15], 15 )
2
And
returns
how_many( [12, 15, 16, 4, 10, 3, 5, 7, 9, 15], 11 )
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
returns
find_bigger( [12, 15, 16, 4, 10, 3, 5, 7, 9, 15], 11 )
[12, 15, 16, 15]
And
returns
find_bigger( [12, 15, 16, 4, 10, 3, 5, 7, 9, 15], 15 )
[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.
