if(sema.get_value!=1):
  #do something

i read this doc but i can't find my answer https://docs.python.org/3/library/threading.html

Answer 1

The other answers are correct but for whom reaches this page in order to actually know how to get the semaphore value you can do it like this:

>>> from threading import Semaphore
>>> sem = Semaphore(5)
>>> sem._Semaphore__value
5
>>> sem.acquire()
True
>>> sem._Semaphore__value
4

Be aware that the _Semaphore__ that prefixes the name of the variable value means that this is an implementation detail. Do not write production code based on this variable as it may change in the future. Moreover do not try to edit the value manually, otherwise.. any bad thing can happen.
