for python 3

Write a recursive function that takes a positive integer, say n, and RETURNS the sum of the integers from 1 to n. Call your function with an argument of your choice and print the results.

Sample Run with argument 123:

The sum from 1 to 123 is 7626.

NOTE: We can add the following two lines to increase Python's recursion depth (1500 can be changed).

import sys sys.setrecursionlimit(1500)
