#2

get_average is a function and it is surrounded by parentheses not square brackets!

#3

here:

``print(get_average[student])``

get_average() is a function call, so it should have parentheses. Also, supply an actual student (lloyd, tyler or alice) as argument

#4

get_average(alice) raised the following error: string indices must be integers, not str

#5

tyler inside a square brackets `[]` ,you can directly pass it get_avaerage()?

hint**
when we pass a variable to a function, we don't use `[]`

also..
You dont need for loop and
these i's.
