8/9 - Part of the whole: get_class_average([alice]) resulted in an error: maximum recursion depth exceeded[SOLVED]


#1

Hi everyone, the problem with my code seems to be very specific, I'm getting this error:

"get_class_average([alice]) resulted in an error: maximum recursion depth exceeded"

And I can't see were the recursion's depth is coming from.

Here's the code:

lloyd = {
"name": "Lloyd",
"homework": [90.0, 97.0, 75.0, 92.0],
"quizzes": [88.0, 40.0, 94.0],
"tests": [75.0, 90.0]
}
alice = {
"name": "Alice",
"homework": [100.0, 92.0, 98.0, 100.0],
"quizzes": [82.0, 83.0, 91.0],
"tests": [89.0, 97.0]
}
tyler = {
"name": "Tyler",
"homework": [0.0, 87.0, 75.0, 22.0],
"quizzes": [0.0, 75.0, 78.0],
"tests": [100.0, 100.0]
}

Add your function below!

def average(numbers):
total = float(sum(numbers))/len(numbers)
return total

def get_average(student):
homework = student["homework"]
quizzes = student["quizzes"]
tests = student["tests"]
return (0.1 * average(student["homework"]) + 0.3 * average(student["quizzes"]) + 0.6 * average(student["tests"]) )

def get_letter_grade(score):
    if score >= 90:
        return "A"
    elif score >= 80:
        return "B"
    elif score >= 70:
        return "C"
    elif score >= 60:
        return "D"
    else:
        return "F"


def get_average(lloyd):
    print get_letter_grade(get_average(lloyd))


def get_class_average(students):
    for student in students:
        re=get_average(student)
    print student 
    results.append(re)
    return average(results)

Can Anyone help? :smile:

Do not call the function its' self in the function.

EXAMPLE OF RECURSIVE FUNCTION

def a_function():
    return a_function()
a_function()

See here,

def get_average(lloyd):
    print get_letter_grade(get_average(lloyd))

That is your issue!

EDIT:

Recursion is only bad if you did not intend to do it!

@zeziba you are absolutely right!

Thanks for the observation :smile:

Looks like no empty list is defined before the 'for' loop
