celery doesn't work with global variable

Question

from celery import Celery

app = Celery(\'tasks\', backend=\'amqp://guest@localhost//\', broker=\'amqp://guest@localhost//\')

a_num = 0

@app.task
def addone():
            


        

Answer 1

The tasks will run asynchronously so every time it starts a new task a_num will be set to 0. They are run as separate instances.

If you want to work with values I suggest a value store or database of some sort.
