sum function in python

# Recursive Algorithm
def sum(items):
    head, *tail = items 
    return head + sum(tail) if tail else head 

sum in python

x = int(10)
y = int(5)
print(x + y)
#you need to define integer extra otherwise
# python will count this as a str and won't work.
#copy the code to your py script to see the accurate result.

sum function python

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
