# Week 6

## 0 Finish last weeks stuff!

There were a lot of exercises last week, try and finish the for/while loop exercises before attempting this weeks material on functions (don't worry about completing the challenge problems though).

## 1 Fun with Functions

#### 1.1 Maximal entertainment <a href="#maximal-entertainment" id="maximal-entertainment"></a>

Create a function which takes in a list and prints out the biggest value in the list (**don't** use pythons max() function!)

**Extension**

Instead, **return** the maximum value and print it outside of the function

#### 1.2 Sum thing to do <a href="#sum-thing-to-do" id="sum-thing-to-do"></a>

Create a function which accepts a **list** of numbers and prints the **sum** of all the numbers

**Extension**

Get your function to return the **average** value in the list (You'll want to use len())

**1.3 Developing a range of skills**

Create a function which mimics the function of range(), by returning a list of integers from the minimum value to the maximum value - 1 (i.e. my\_range(min, max))

**Extension 1**

Use **default arguments** such that if the "min" argument is not given, the function starts counting from zero

**Extension 2**&#x20;

Try and implement the range function using recursion (you can use another function to do the actual list creation, if you like, so long as it uses recursion!)
