Terry J. Reedy added the comment: Peter Otten thought the first clause should instead be ""Data attributes and method attributes share the same namespace.", which is also true for a given object. This is a different intepretation of what the original author was getting at. The convention remar

Terry J. Reedy added the comment: Small int caching saves both time and space. On a nearly fresh IDLE session: >>> sys.getrefcount(0) 772 >>> sys.getrefcount(1) 854 >>> sum(sys.getrefcount(i) for i in range(-5, 257)) 4878 While an interesting idea, I do not see the same gain here, and agree with
