Python program to find sum of elements in list

Given a list of numbers, write a Python program to find the sum of all the elements in the list.

Example:

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

Input: [17, 5, 3, 5]
Output: 33

Example #1:

# 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 variale total 
for ele in range(0, len(list1)): 
    total = total + list1[ele] 
  
# printing total value 
print("Sum of all elements in given list: ", total) 

Output:

Sum of all elements in given list:  74

Example #2 : Using while() loop

# 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 variale total 
while(ele < len(list1)): 
    total = total + list1[ele] 
    ele += 1
      
# printing total value 
print("Sum of all elements in given list: ", total) 

Output:

Sum of all elements in given list:  74

Example #3: Recursive way

# 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) 

Output:

Sum of all elements in given list:  74

Example #4: Using sum() method

# 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) 

Output:

Sum of all elements in given list:  74
