Python implements calculating the sum of list elements

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
