Here are some function exercises for you to apply what you have just learnt.

Templates for the answers have been given so just add on to it! If you don't want to use it that fine too. There are many ways you can write a function to do the same thing.

Have fun!

Write a recursive function that will return the nth term of the Fibonacci sequence.

The sequence has a relationship of `Fn = Fn-1 + Fn-2`

with `F0 = 0`

and `F1 = 1`

, where `n=0,1,2,3,4,5,...`

The sequence looks like: `0,1,1,2,3,5,8,13,...`

def fibonaci(n): """return the full fibonaci sequence""" if n == 0: return 0 elif n == 1: return 1

Write a function that will count how many odd numbers is present in a given list of integers.

Fill in the function below.

Hint: Use this list to check your function

[1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20]

[1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20]

def count_odd_numbers(numbers): count = 0 for i in ____: if ____ % 2 == _____: count += ____ return ____
