```pythondef sum_of_evens(numbers): return sum(num for num in numbers if num % 2 == 0)``` 解决该问题的步骤如下:1. **问题分析**:需要计算一个整数列表中所有偶数的和。核心步骤是过滤偶数,然后求和。2. **判断条件**:判断一个数是否为偶数可通过 `num % 2 == 0` 实现。3.
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。 ```python def average_even(numbers): evens = [x for x in numbers if x % 2 == 0] if len(evens) == 0: return 0 return sum(evens) / len(evens) numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]...
Let's start writing a Python program using the above algorithm in a simple way. Python program to find the sum of all prime numbers # input the value of NN=int(input("Input the value of N: "))s=0# variable s will be used to find the sum of all prime.Primes=[Trueforkinrange(N...
Write a program to input an integer N and print the sum of all its even digits and sum of all its odd digits separately. Digits mean numbers, not the places! That is, if the given integer is "13245", even digits are 2 & 4 and odd digits are 1, 3 & 5. ...
Write a Python program to calculate the sum of the numbers in a list between the indices of a specified range. Sample Solution: Python Code: # Define a function 'sum_Range_list' that calculates the sum of a specified range within a listdefsum_Range_list(nums,m,n):# Initialize 'sum_ra...
def sum_even_numbers(numbers): return sum(num for num in numbers if num % 2 == 0) 要解决这个问题,需编写一个函数计算列表中所有偶数的和。步骤如下:1. **遍历列表元素**:使用生成器表达式逐个访问输入列表中的元素。2. **筛选偶数**:通过条件`num % 2 == 0`检查每个元素是否为偶数。3. **...
