编写一个Python函数,接收一个整数列表作为参数,返回列表中所有偶数的平均值。```pythondef average_even(numbers):evens = [x for x in numbers if x % 2 == 0]if len(evens) == 0:return 0return sum(evens) / len(evens)numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]print(a
A mean is defined as the mathematical average of two or more values. There are different ways to calculate the average of all the number elements in the list. for example, you can use the sum() built-in function along with len(). Besides this, there are several other ways to get the...
