I am trying to complete the 'Sending a letter' excercise where you compute the letter grades for the three students.
I expect to see grades, but instead keep getting an error message saying that the function is not 'iterable':
Traceback (most recent call last):
File "python", line 44, in <-- line 44 is the last 'Print' statement
File "python", line 33, in get_letter_grade <-- line 33 is "for z in get_letter_grade:"
TypeError: 'function' object is not iterable
I did not expect the last line to return a syntax error, as the 'hint' shows the same line.
MY CODE (minus the student dictionaries):
def average(numbers): total = sum(numbers) total = float(total) return total / len(numbers) student = [lloyd, alice, tyler] def get_average(student): return 0.10 * average(student["homework"]) + \ 0.30 * average(student["quizzes"]) + \ 0.60 * average(student["tests"]) def get_letter_grade(score): for z in get_letter_grade: if score >= 90: return "A" elif score >= 80: return "B" elif score >= 70: return "C" elif score >= 60: return "D" else: return "F" print get_letter_grade(get_average(lloyd))
