How do you find the sum of certain elements in a list in Python?Syntax. Example: sum(list) sum(list, start). Code Example: # Python code to explain working on sum() method # Declare list of numbers numlist = [2,4,2,5,7,9,23,4,5] numsum = sum(numlist) print('Sum of List: ',numsum) # Example with start numsum = sum(numlist, 5) print('Sum of List: ',numsum).
