Write a pytest and a function get$\_$odd$\_$numbers$($values$).$ The test should validate that the function returns all odd numbers from a list.

Write the test and the function that implements the logic. For example if values $=[2,5,8,1]$ then it should return $[5,1]$

Write a pytest and a function get$\_$courses$($major$,$ values$)$ where major is two character word and values is a list of course numbers.

For example, get$\_$courses$(\text{'}$cs$\text{'},$ values$=[\text{'}$hi$24\text{'},\text{'}$cs$504$B$\text{'},\text{'}$cs $604$B$\text{'},\text{'}$CS $512$ B$\text{'},\text{'}$Ma $3434\text{'}]$ returns $[\text{'}$cs$504$B$\text{'},\text{'}$cs $604$B$\text{'},\text{'}$CS $512$ B$\text{'}]$
