Continue to get indexing out of range error

Here is my code: *Student_IDs is a dictionary

def avg_GPAwork(work_choice):

    work = []
    work = list((Student_IDs.values()))
    print(work)

    for hours in range(len(work)):
        student_hours = work([hours][6])
        print(student_hours)

Here is what work is:

[
    ['Childs, Julia', '9939456', '12/12/1993', 'Computer Science', '3.89', '8'],
    ['Gaga, Lady', '7733469', '10/10/1980', 'Computer Science', '1.20', '40'],
    ['Joe, Billy', '80978632', '01/10/1992', 'Undeclared', '2.4', '25'],
    ['Armstrong, Lance', '0034728', '07/21/1993', 'Computer Science', '3.47', '10'],
    ['Cronkite, Walter', '4357349', '10/02/1992', 'Math', '3.21', '0'],
    ['Williams, Serena', '8453392', '02/14/1994', 'Math', '3.09', '5'],
    ['Harmond, Josh', '30145692', '12/03/1994', 'Biology', '3.9', '0'],
    ['Pawlakos, Eric', '1234567', '05/23/1993', 'Statistics', '3.8', '8']
]

I continue to get an indexing out of range error. What am I doing wrong/how can i fix it?

work([hours][6])

I don't know what you think that does, but it doesn't do what you're thinking. You probably wanted the following:

work[hours][5]

The first problem is that your parentheses cause the expression to be parsed as "Call the object work as if it were a function. The argument should be determined by creating a 1-element list [hours], then getting the element at position 6".

The second problem is that indexing starts from 0, so if you want the 6th element, that's at index 5.

Note: range-len iteration is almost never a good idea. If you want to iterate over the elements of a list, do so directly:

for item in work:
    student_hours = item[5]
    print(student_hours)

or better yet, scrap the first half of the function and iterate over Student_IDs.values() directly:

for item in Student_IDs.values():
    student_hours = item[5]
    print(student_hours)
