Python help: I am very confused on what to do. It needs to be a while loop but i have no clue how to go about this! All the info is below!

Write a function called addmax(list, threshold) that adds up as many elements as possible from a list starting from the first item with sum less than a given threshold.(hint: use while loop)

For example,

print addmax([2,3,5,7],6) will get 5

print addmax([2,3,5,7],11) will get 10#because 2+3+5=10< 112+3+5+7=17>11

define your function below:
