Do these numbers add up?

From Computer Science Wiki
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:

  1. to build your skill applying computational thinking to a problem
  2. to assess your knowledge and skills of different programming practices


What is this problem set trying to do[edit]

In this example we are learning about lists, iteration, and conditionals.

The Problem[edit]

I found this problem on Daily Coding Problem, a site you should sign up for so you can practice your problem sets[2]

Given a list of numbers and a number k, return whether any two numbers from the list add up to k.

For example, given [10, 15, 3, 7] and k of 17, return true since 10 + 7 is 17.

Hacker edition[edit]

In the hacker version:

Can you do this in one pass?

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)
