My Code is not working and I don’t know why.

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]
}

students= [tyler, lloyd, alice]
def average(student):
  total= float(sum(student))
  total= total/float(len(student))
  return total
def get_average(student):
  homework=average(student["homework"])
  quizzes=average(student["quizzes"])
  tests=average(student["tests"])
  weighted_total= homework*.1 + quizzes*.3 + tests*.6
  return weighted_total
#for student in students:
  #student["weighted average"]= get_average(student)
print average(tyler["homework"])
print get_average(alice)
print lloyd
def get_letter_grade(average):
  if average >= 90:
    return "A"
  elif average >= 80:
    return "B"
  elif average >= 70:
    return "C"
  elif average >= 60:
    return "D"
  elif average<60:
    return "F"
  else:
    return "Something's wrong"
 
print get_letter_grade(get_average(lloyd))
def get_class_average(class_list):
  results=[]
  for student in class_list:
    results.append(get_average(class_list)
  average(results)
  return results               
print get_class_average(students)

the exercise url is for myself, if i have to help you further, i can more quickly access the exercise

there are two problems in this line:

results.append(get_average(class_list)

first, count your parentheses.

second, get_average is designed to get the average of a student (lloyd for example), this is why we use a loop to get student from class_list
