Python 计算数组元素之和
Python3 实例
定义一个整型数组,并计算元素之和。
实现要求:
输入 : arr[] = {1, 2, 3}
输出 : 6
计算: 1 + 2 + 3 = 6
实例
# 定义函数,arr 为数组,n 为数组长度,可作为备用参数,这里没有用到
def _sum( arr, n) :
# 使用内置的 sum 函数计算
return ( sum ( arr) )
# 调用函数
arr= [ ]
# 数组元素
arr = [ 12 , 3 , 4 , 15 ]
# 计算数组元素的长度
n = len ( arr)
ans = _sum( arr, n)
# 输出结果
print ( '数组元素之和为' , ans)
以上实例输出结果为:
数组元素之和为 34

用for循环实现:
list=[1,3,5,7,9,34] sum=0 for i in range(0,len(list)): sum+=list[i] print(sum)学习者
