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
lists have a count() method.
try this:
honor_roll_count = student_grades.count('A') + student_grades.count('B')
For more complex data sets you could use the itertools groupby function too.
