Python程序查找列表中元素的总和

给定一个数字列表，编写一个Python程序来查找列表中所有元素的总和。
例子：

Input: [12, 15, 3, 10]
Output: 40

Input: [17, 5, 3, 5]
Output: 30

示例 #1：

Python3

# Python program to find sum of elements in list
total = 0
 
# creating a list
list1 = [11, 5, 17, 18, 23]
 
# Iterate each element in list
# and add them in variable total
for ele in range(0, len(list1)):
    total = total + list1[ele]
 
# printing total value
print("Sum of all elements in given list: ", total)

输出：

Sum of all elements in given list:  74

示例 #2：使用 while() 循环

Python3

# Python program to find sum of elements in list
total = 0
ele = 0
 
# creating a list
list1 = [11, 5, 17, 18, 23]
 
# Iterate each element in list
# and add them in variable total
while(ele < len(list1)):
    total = total + list1[ele]
    ele += 1
     
# printing total value
print("Sum of all elements in given list: ", total)

输出：

Sum of all elements in given list:  74

示例#3：递归方式

Python3

# Python program to find sum of all
# elements in list using recursion
 
# creating a list
list1 = [11, 5, 17, 18, 23]
 
# creating sum_list function
def sumOfList(list, size):
   if (size == 0):
     return 0
   else:
     return list[size - 1] + sumOfList(list, size - 1)
  
# Driver code    
total = sumOfList(list1, len(list1))
 
print("Sum of all elements in given list: ", total)

输出：

Sum of all elements in given list:  74

示例 #4：使用 sum() 方法

Python3

# Python program to find sum of elements in list
 
# creating a list
list1 = [11, 5, 17, 18, 23]
 
# using sum() function
total = sum(list1)
 
# printing total value
print("Sum of all elements in given list: ", total)

输出：

Sum of all elements in given list:  74
