Python: Three integers are read from input into variables age$1,$ age$2,$ and age$3.$ Assign avg$\_$age$\_$per$\_$beaver with the average age per beaver. Then, convert avg$\_$age$\_$per$\_$beaver to an integer.

Ex: If the input is:

$15$

$19$

$16$

then the output is:

$16$

Note: The average is the sum of all values divided by the number of values.
