The use of Noneis cumbersome and unintuitive. It requires defining additional functions for
addition and substation.
Describe the solution you'd like
Use math.nan
Describe alternatives you've considered
If numpy is installed you can also use the NaN from numpy and the manipulation functions from
there. You can use a try-catch in the import statement to replace the nan and the methods from math and statistics with the ones from numpy.
