Write a Python package with sub$-$packages, modules, and functions using keyword arguments. Use the following directory outline and module names $($your first starting point should be a directory called $`$mathematics$`$ within your $`$lab$05-$username$`$ directory$)$:

$```$

mathematics$/$

$\_\_$init$\_\_.$py

whoami.py

numbers$/$

$\_\_$init$\_\_.$py

whoami.py

series.py

simple.py

geometry$/$

$\_\_$init$\_\_.$py

whoami.py

rectangle.py

circle.py

cube.py

$```$

$1.$ Create a $`$mathematics$`$ package.

$1.$ Initialize the $`\_\_$all$\_\_`$ variable to the $`$whoami$`$ module.

$1.$ Create a $`$whoami$`$ module.

$1.$ Create a function named $`$getname$`$ which returns the $`\_\_$name$\_\_`$ variable.

$1.$ Create a $`$numbers$`$ sub$-$package.

$1.$ Initialize the $`\_\_$all$\_\_`$ variable to the $`$whoami$`$ and $`$series$`$ modules.

$1.$ Create a $`$whoami$`$ module.

$1.$ Create a function named $`$getname$`$ which returns the $`\_\_$name$\_\_`$ variable.

$1.$ Create a $`$series$`$ module.

$1.$ Create a function named $`$sum$`$ which receives a keyword parameter $`$list$`$ and returns the sum of all the values in the list.

$1.$ Create a function named $`$average$`$ which receives a keyword parameter $`$list$`$ and returns the average of all the values in the list.

$1.$ Create a $`$simple$`$ module.

$1.$ Create a function named $`$addition$`$ which receives the keyword parameters $`$left$`$ and $`$right$`$ and returns left plus right.

$1.$ Create a function named $`$subtraction$`$ which receives the keyword parameters $`$left$`$ and $`$right$`$ and returns left minus right.

$1.$ Create a function named $`$multiplication$`$ which receives the keyword parameters $`$left$`$ and $`$right$`$ and returns left multiplied by right.

$1.$ Create a function name
