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
Learn how to calculate the average of a set of numbers in Python. This program demonstrates how to iterate through a list of numbers, calculate the sum, and divide by the total number of elements to find the average. Follow along with the code and try it
How to find the average or mean of elements in the list in Python? 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 alon...
A weighted average is an average in which some of the items to be averaged are 'more important' or 'less important' than some of the others. The weights are (non-negative) numbers which measure the relative importance For example, the weighted average of a list of numbers x1,…,xnwith ...

我们可以将该类加载到 Python 3 解释器中,这样我们就可以交互式地使用它。为了做到这一点,将前面提到的类定义保存在一个名为first_class.py的文件中,然后运行python -i first_class.py命令。-i参数告诉 Python运行代码然后转到交互式解释器。以下解释器会话演示了与这个类的基本交互:...
