Python - sort lists based on their sum

Question

I want to sort a list that contains lists based on the sum of each inner list.

here\'s the current snippet I\'ve got

vectors = []
for i in range(0, 1         


        

Answer 1

vectors = []
for i in range(0, 10):
    vectors.append(generate_vector()) # generate_vector() works, creates a list

for vector in vectors:
    coin_list = findbest(vector) # findbest(vector) outputs a list
    print sorted(fitness(coin_list), key=sum)
