[Tutor] Printing a list count - Help

[Derek Jenkins]

Hi everybody,

I have a list that I want to go through and finally print a total
count of particular items. In this case, I want to print the result of
how many A's and B's are in the list.

honor_roll_count = 0
student_grades = ["A", "C", "B", "B", "C", "A", "F", "B", "B", "B", "C", "A"]

for grades in student_grades:
    honor_roll_count = honor_roll_count + 1
    if grades == "A" or grades == "B":
        print honor_roll_count

The above code prints 8 lines, each being an entry for which item in
the list was either A or B. Again, I'm looking for the result to be
the number 8 itself - the total number of instances that A or B occurs
in the list.

I'm sure there are a handful of easy solutions for this, I just
haven't hit the right combo yet and I thought I'd reach out to the
tutor list for a bit of advice.

Please and thank you!
