Nobody in their right mind wants to receive an email from Mr. Otten.  ;)

In your code, include:

   import math
   eleven = math.sqrt(121)

You also said statistics.  If you are looking for the basic tools, 
then you can find them here:

   https://docs.python.org/3/library/statistics.html#module-statistics

Thggere are other, richer tools in third-party libraries if you are 
looking for more advanced tools.  But, perhaps you only need to 
start with the above.

Good luck,

-Martin
