How to know reactor is running or not in python?

python, python-2.7, reactor, twisted, twisted.internet

Solution

You do not state which reactor you are using, but this page says `ReactorBase` is the base class for Reactors.

Also on the same page, it mentions an instance variable `running` that is further explained here.

It says

running = A bool which is True from during startup to during shutdown and False the rest of the time.

With that information we can change your code to:

if reactor.running:
    # do some work

Problem

How to know reactor status (running or not) ? I tried this(searched from google): ``` from twisted.internet import reactor if reactor.callWhenRunning(lambda: None) is not None: # do some work ``` It worked, but this seems like weird way. What can be other ways of doing this ?
