This a problem set for you to work through ^[1]

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]

This is example problem set. In this example we are learning about lists and conditionals.

The Problem[edit]

Please consult the image of a leaderboard below

You must design an algorithm which creates the total number of points. The algorithm accepts as input a comma delimited list:

USER ID, BADGES, CHALLENGES, VIDEOS, QUIZZES

For QUIZZES, the input is passed as a 2 dimensional list indicated the quiz number and the number of attempts. Please see below for two different examples of inputs:

1234, 3, 12, 13, [[1,1],[2,5],[3,1],[4,2]]

In the example above, user 1234 has 3 badges, 12 challenges, 13 videos and has the following quiz data:

for quiz 1, there was 1 attempt
for quiz 2, there was 5 attempts
for quiz 3, there was 1 attempt
for quiz 4 there were 2 attempts.

Your program should output the user ID and the number of points that user has earned. You will need to decide how the points are calculated (cool, math!). An example of out should look like:

1234, 340

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?

user1 = [123, 4, 13, 6, [[1,1],[2,5],[3,1],[4,2]]]
user2 = [842, 7, 20, 7, [[1,8],[2,4],[3,9],[4,20]]]
user3 = [945, 9, 12, 25, [[1,3],[2,1],[3,4],[4,34]]]

def find_total_points(user):
    for i in range (0, len(user[4])):
        quiz_points = 0
        quiz_points = quiz_points + user[4][i][-1]
    total_points = user[1]*287 + user[2]*31 +user[3]*2 +quiz_points
    return user[0], total_points

print("User with ID:", find_total_points(user1)[0] , "has" , find_total_points(user1)[1] , "total points.")
print("User with ID:", find_total_points(user2)[0] , "has" , find_total_points(user2)[1] , "total points.")
print("User with ID:", find_total_points(user3)[0] , "has" , find_total_points(user3)[1] , "total points.")
