Average in a stream

Python Program

Given a stream of incoming numbers, find average or mean of the stream at every point.

Example 1:

Input:
n = 5
l = [10, 20, 30, 40, 50]
Output: 10.00 15.00 20.00 25.00 30.00 
Explanation: 
10 / 1 = 10.00
(10 + 20) / 2 = 15.00
(10 + 20 + 30) / 3 = 20.00
And so on.
