The python sum() function is used to sum all items in an iterable. Actually, this function adds the items of an iterable and returns the sum.
Example sum function in Python
Simple example code sum of a given integer list.
a = [1, 2, 3, 4, 5] res = sum(a, 7) print(res) print(type(res))
To add floating-point numbers with exact precision, then you should use math.fsum(iterable) instead.
Without start parameter
a = [1, 2, 3, 4, 5] res = sum(a) print(res)
