python - 查找列表的平均值(Finding the average of a list)

Question

I have to find the average of a list in Python.

(我必须在Python中找到列表的平均值。)

This is my code so far

(到目前为止，这是我的代码)

l = [15, 18, 2, 36, 12, 78, 5, 6, 9]
print reduce(lambda x, y: x + y, l)

I've got it so it adds together the values in the list, but I don't know how to make it divide into them?

(我已经知道了，所以它可以将列表中的值相加，但是我不知道如何将其划分为它们？)

Answer 1

l = [15, 18, 2, 36, 12, 78, 5, 6, 9]
sum(l) / len(l)
