I would have added them as functions in the math module instead. perhaps supported by dunder methods (asintegerratio, isinteger). But that's not what happened, and whether or not they have double underscores on each end doesn't really make all that much difference except to dedicated pedants ;-)

Yes, this was my point. In spite of the fact that the pronouncement has already been made, there may still be an opportunity to influence this decision. I do not think that this is only a matter of choice, how this functionality will be accessed through a method or function, in fact these highly specialized methods heavily pollute the API and open the door for persistent questions. Given the frequency and activity of using this .is_integer method the deprecation of this method is unlikely to greatly affect someone. (for as_integer_ratio I think the bar is higher). Summarizing this thread it seems to me that with deprecation of is_integer method and with addition of is_integer function in math module will make everyone happy:

PROS:

  1. Those who do not like this method, and do not want to see it as a redundant part of int, ... will be happy
  2. Those who need it will have this functionality through math module
  3. Compatible packages do not have to quack louder
  4. Cleaner API (no need to add this through numeric tower)
  5. Make everyone happy and stop this thread :)

CONS:

  1. Backward incompatible change

I do not want to restart this topic, but I think that there is an opportunity for improvement that can be missed.
