这是题目,只有英文的:Write a function average that takes a list of numbers and returns the average.1. Define a function called average that has one argument, numbers.2. Inside that function, call the built-in sum() function with the numbers list as a parameter. Store the result in 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
odd_numbers = [num for num in numbers if num % 2 != 0] average = sum(odd_numbers) / len(odd_numbers) print("奇数的平均值为:", average) ``` 查看本题试卷 python列表平均数怎么求_Python中输入一个数值列表,并求出其平均值 112阅读 1 python从键盘输入一个列表计算输出元素的平均值_pytho...

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
numbers = [1, 2, 3] print(numbers[3]) # IndexError: list index out of range2.1.2 自定义异常类 除了使用内置异常,我们还可以根据项目需求创建自定义异常类。这样做有助于提高代码可读性和异常处理的针对性。自定义异常通常继承自Exception类或其他合适的内置异常。

因此,我们的猜测是正确的:如果我们没有user_rating_count,那么我们也没有average_user_rating(如果是这种情况,那么我们将不得不分别处理这两列的缺失值)。回到列的描述(介绍数据集部分)中,对于用户评分计数,我们发现“null 表示低于 5”,因此如果少于 5 个人对游戏进行评分,那么我们根本没有评分。
