Goal: Define a list of numbers and calculate the sum of the list elements.
For example: Input: [12, 15, 3, 10] Output: 40
Method 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)Result:
列表元素之和为: 74
Method 2: Use while() loop
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)The output result of the above example is:
列表元素之和为: 74
Method 3: Use recursion
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)The result:
列表元素之和为: 74
