定义一个数字列表,并计算列表元素之和。
例如:输入 : [12, 15, 3, 10]输出 : 40实例 1
total = 0
list1 = [11, 5, 17, 18, 23]
for ele in range(0, len(list1)):
total = total + list1[ele]
print("列表元素之和为: ", total)
list1 = [11, 5, 17, 18, 23]
for ele in range(0, len(list1)):
total = total + list1[ele]
print("列表元素之和为: ", total)
以上实例输出结果为:
列表元素之和为: 74
实例 2: 使用 while() 循环
total = 0
ele = 0
list1 = [11, 5, 17, 18, 23]
while(ele < len(list1)):
total = total + list1[ele]
ele += 1
print("列表元素之和为: ", total)
ele = 0
list1 = [11, 5, 17, 18, 23]
while(ele < len(list1)):
total = total + list1[ele]
ele += 1
print("列表元素之和为: ", total)
以上实例输出结果为:
列表元素之和为: 74
实例 3: 使用递归
list1 = [11, 5, 17, 18, 23]
def sumOfList(list, size):
if (size == 0):
return 0
else:
return list[size - 1] + sumOfList(list, size - 1)
total = sumOfList(list1, len(list1))
print("列表元素之和为: ", total)
def sumOfList(list, size):
if (size == 0):
return 0
else:
return list[size - 1] + sumOfList(list, size - 1)
total = sumOfList(list1, len(list1))
print("列表元素之和为: ", total)
以上实例输出结果为:
列表元素之和为: 74
