# Python program to find the sum of items in a list

|

Example :

`  Input:  [12, 15, 3, 10]  Output:  40  Input:  [17, 5, 3, 5]  Output:  33 `

Example # 1:

` `

` < / code> Exit : Sum of all elements in given list: 74 Example # 2. Using a while () loop # Python program for finding the sum of items in a list total = 0    # create a list list1 = [ 11 , 5 , 17 , 18 , 23 ]     # Iterate each item in the list # and add them in total for ele in range ( 0 , len (list1)):   total = total + list1 [ele]    # print total cost print ( "Sum of all elements in given list:" , total) # Python program for finding the sum of items in a list total = 0 ele = 0    # create a list list1 = [ 11 , 5 , 17 , 18 , 23 ]    # Iterate each item in the list # and add them in total while (ele & lt;  len (list1)): total = total + list1 [ele] ele + = 1   # print total cost print ( "Sum of all elements in given list:" , total) `

Output:

` Sum of all elements in given list: 74 `

Example # 3: recursive way

` `

` < td class = "code"> # Python program to find the sum of all # items in the list using recursion   # create a list list1 = [ 11 , 5 , 17 , 18 , 23 ]   # creating the 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) `

` `

Exit :

` Sum of all elements in a given list: 74 `

Example # 4: Using the

` # Python program for finding the sum of items in a list `

` `
` # create a list `

` list1 ` ` = ` ` [` 11 `, ` ` 5 ` `, ` ` 17 ` `, ` ` 18 ` `, ` ` 23 ` `] `

` # using the sum () function `

` total ` ` = ` ` sum ` ` (list1) `

` # print total cost `

` print ` ` (` ` "Sum of all elements in given list:" ` `, total) `

Exit:

` Sum of all elements in given list: 74 `
