Just use `from statistics import mean as avg` (see https://docs.python.org/3/library/statistics.html#statistics.mean).

Please provide some justification on why do you think it's desirable to make `avg` a builtin, considering, that doing so is a backwards incompatible change due to the more than likely name clash.

Hello,

I think it would be nice to introduce an avg method for lists as a built-in function in python3.
To get average of the list, I need to use some libs (eg numpy). 
In my opinion, if I can get sum of the list, I should get avg also in a same way.

For ex [python3]: 

>>> l = [5, 9, 7,]
...
... import numpy as np
... print(np.mean(l))
7.0
>>> sum(l) / len(l)
7.0
>>> avg(l)
Traceback (most recent call last):
  File "<input>", line 1, in <module>
NameError: name 'avg' is not defined

Cordialement/Regards
