What does can't assign to function call mean (python) [closed]

Answer 1

I'm guessing that you want to pass a list of grades to your average() function.

You have the syntax a bit mixed up in grades.sum() = total and total.float() = total

You (probably) want something like this:

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

And you'd call that function like this:

avg = average(alice["homework"])

total = sum(grades) says calculate the sum of the values in grades and store the result in a variable named total. The function call sum(grades) asks a question, and in Python (like most other programming languages) we write the question on the right side of the = sign, and the place to put the answer goes on the left side of the = sign. But your code has that backwards.
