List of lists- how to call it?


#1




Traceback (most recent call last):
File "python", line 21, in
TypeError: list indices must be integers, not dict


The names of the sub-lists will be printed


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 = [lloyd, alice, tyler]
for item in students:
    print students[item]["name"]


#2

item will be assigned the list values, let me show you:

for item in students:
    print item

so item will now hold the dictionary, so if yo want the name you can simply do:

print item["name"]
