Function Details: sum

Description

Returns the sum of a 'start' value (default: 0) plus an iterable of numbers.

Extended Description

The sum() function adds the items of an iterable from left to right and returns the total. It starts with the optional 'start' value (which defaults to 0) and adds each item from the iterable to it. For numbers, it's equivalent to using the + operator in a loop. However, sum() is preferred for better performance and readability. Note that sum() is not recommended for concatenating strings; it's better to use ''.join(sequence) for that purpose.
