Python's sum(~) method adds the items of an iterable from left to right and returns the total.

Parameters

1. iterable | iterable

The iterable whose items are to be added. The elements of the iterable should be numbers.

2. startlink | number | optional

This value to add to the total. Default is 0.

Return value

Returns the total sum of items of the provided iterable plus the start if applicable.

Examples

Basic usage

To return the sum of elements in the list numbers:

numbers = [12, 3, 6, 4, 8]
sum(numbers)
33

Start parameter

To specify a start of 10 when summing the numbers list:

numbers = [12, 3, 6, 4, 8]
sum(numbers,10)
43

Note that 10 is added to the sum of the elements in numbers (33) giving us a return value of 43.
