Python attributeError on __del__

Question

I have a python class object and I want to assign the value of one class variable

class Groupclass(Workerclass):
    \"\"\"worker class\"\"\"
    count = 0

         


        

Answer 1

When __del__() method called, the Groupclass may be recovered by the garbage collection mechanism, so using Groupclass.xxx may failed. But you can access the count variable through self.__class__.count. Code likes below:

def __del__(self):
    self.__class__.count -= 1
