Raymond Hettinger added the comment:

The wording can perhaps be made more precise.  However, this needs to be the 
end of this series of tracker items which are turning into time wasters.

[issue29023] Results of random.seed() call with integer argument should be claimed deterministic.

[Jakub Mateusz Kowalski]

New submission from Jakub Mateusz Kowalski:

In https://docs.python.org/2/library/random.html#random.seed I can find that 
"If a hashable object is given, deterministic results are only assured when 
PYTHONHASHSEED is disabled."

Both int and long are hashable. However, tests on the random module as well as 
C source code of random_seed (as indicated in 
http://stackoverflow.com/a/41228062/4879688) suggest that behaviour of the 
module is deterministic when seeded with an integer.
