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
在Python中，可以使用内置的sum()和len()函数来计算平均数。sum()函数可以对一个列表进行求和，而len()函数可以计算列表中元素的数量。将这两个函数的结果相除即可得到平均数。具体代码如下：numbers = [1, 2, 3, 4, 5]average = sum(numbers) / len(numbers)print("The average is:", averag...
Python Average program In this python program we will learn to calculate the average of number for N numbers. Average is the sum of items divided by the number of items. Here, we’ll calculate the sum and average of a natural number as listed by the user. Algorithm: Declare variables n...

在Python中,可以使用如下的方法来求一个列表中所有元素的平均值:```pythondef calculate_average(numbers): total = sum(number...
# Average Score: 273.6 5. Using reduce with Lambda Expression Here, we will uselambda expressionas a mathematical expression that will return the average of elements present in the python list. We will first add numbers and then divide this sum by the total number of elements present in the...
def calculate_average(numbers): total = sum(numbers) average = total / len(numbers) return average # 调用函数 scores = [85, 92, 78, 90, 88] average_score = calculate_average(scores) print("平均分数是:", average_score) 这个函数calculate_average接受一个数字列表作为参数,计算出平均值并返回...
Python,又有不懂了。 这是题目,只有英文的: Write a function average that takes a list of numbers an
print("\nAverage value of the numbers of the said tuple of tuples:\n", average_tuple(nums)) Sample Output: Original Tuple: ((10, 10, 10, 12), (30, 45, 56, 45), (81, 80, 39, 32), (1, 2, 3, 4)) Average value of the numbers of the said tuple of tuples: [30.5, ...
print(“平均数:”, average) “` 输出结果: “` 平均数: 15 “` 在以上代码中,首先导入了statistics库,并使用statistics.mean()函数计算numbers列表中的平均数。最后,将结果打印出来。 总结一下,在Python中,有多种方式可以计算平均数,包括使用内置的sum()和len()函数、使用numpy库中的mean()函数,以及使用统...
