This is a problem set. Some of these are easy, others are far more difficult. The purpose of these problems sets are:
- to build your skill applying computational thinking to a problem
- to assess your knowledge and skills of different programming practices
What is this problem set trying to do[edit]
If it has been a while since you have coded, these are the problem sets for you!
Problem 1[edit]
Consider the following list. Write a program that prints the very first item in the list and the very last item in the list. Each print statement should be on a different line.
[10, 15, 3, 7]
Your output should be:
10
7
You might want to review our wiki article on Lists (especially the parts on slicing).
When you get this, construct a function which accepts a list as a parameter and returns the first and last value of a list.
You might want to review our wiki article on Functions in Python if you need a reminder about functions.
Problem 2[edit]
Consider the following list. Write a program which iterates through the list, printing each item on the list on a different line.
[10, 15, 3, 7,12,33,65,45,24,9,8]
Your output should be:
10
15
3
7
33
65
45
24
9
8
You might want to review our wiki article on Iteration if you get stuck.
Problem 3[edit]
Consider the following list. Write a program which iterates through the list, and at each iteration, checks if the number is even or odd.
[10, 15, 3, 7,12,33,65,45,24,9,8]
Your output should be:
10 even
15 odd
3 odd
7 odd
12 even
33 odd
65 odd
45 odd
24 even
9 odd
8 even
You might want to review our wiki article on Modulo in Python and Conditionals if you get stuck.
Problem 4[edit]
Consider the following list.
["abb","vcv","qwe","kli","der","sae","ghf","ref","h1","h5p"]
Write a program which asks the user for input and then searches the list to see if what the user input is in the list.
Your output should be:
Enter a 3 letter code:
If the code is in the list the input should state:
that code is in the list
If the code is not in the list the input should state:
that code is not in the list
You might want to review our wiki article on Conditionals if you get stuck.
How you will be assessed[edit]
Your solution will be graded using the following axis:
Scope
- To what extent does your code implement the features required by our specification?
- To what extent is there evidence of effort?
Correctness
- To what extent did your code meet specifications?
- To what extent did your code meet unit tests?
- To what extent is your code free of bugs?
Design
- To what extent is your code written well (i.e. clearly, efficiently, elegantly, and/or logically)?
- To what extent is your code eliminating repetition?
- To what extent is your code using functions appropriately?
Style
- To what extent is your code readable?
- To what extent is your code commented?
- To what extent are your variables well named?
- To what extent do you adhere to style guide?

list = [1,2,3,4,5,6,7,8,9]
k = 28
def add(list , target):
if any(list) + any(list) == target:
print("True")
else:
print("False")
add(list, k)
