Syntax: sum(iterable, start) iterable : iterable can be anything list , tuples or dictionaries , but most importantly it should be numbers. start : this start is added to the sum of numbers in the iterable. If start is not given in the syntax , it is assumed to be 0. Possible two syntaxes: sum(a) a is the list , it adds up all the numbers in the list a and takes start to be 0, so returning only the sum of the numbers in the list. sum(a, start) this returns the sum of the list + start Below is the Python implementation of the sum() Python3
