Python sum()
The sum() function adds the items of an iterable and returns the sum.
Example
marks = [65, 71, 68, 74, 61]
# find sum of all marks
total_marks = sum(marks)
print(total_marks)
# Output: 339
sum() Syntax
The syntax of the sum() function is:
sum(iterable, start)
The sum() function adds start and items of the given iterable from left to right.
sum() Parameters
- iterable - iterable (list, tuple, dict, etc). The items of the iterable should be numbers.
- start (optional) - this value is added to the sum of items of the iterable. The default value of start is 0 (if omitted)
sum() Return Value
sum() returns the sum of start and items of the given iterable.
Example: Working of Python sum()
numbers = [2.5, 3, 4, -5]
# start parameter is not provided
numbers_sum = sum(numbers)
print(numbers_sum)
# start = 10
numbers_sum = sum(numbers, 10)
print(numbers_sum)
Output
4.5 14.5
If you need to add floating-point numbers with exact precision, then you should use math.fsum(iterable) instead.
If you need to concatenate items of the given iterable (items must be strings), then you can use the join() method.
'string'.join(sequence)
