# Do these numbers add up?

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

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

## The Problem

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

In the hacker version:

Can you do this in one pass?

## How you will be assessed

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?

```#Filip
list = [10, 15, 3, 7]
k = 22

def add_up(list, k):
fit = False
for a in list:
for x in range(len(list)):
if a+list[x] == k:
fit = True
return fit

print(add_up(list, k))
```
