How to import a method or use that from another class in python?


How to import a method or use that from another class in python?

seems to work fine I'm not sure what you are asking, but you need to import that class in the file that has the Root class:
code :
# twisted.py file
from ldapConnector import MyClass

class Root():
    def __init__(self):
        MyClass().getConnections()

like below fixes the issue
You probably made a typo in your example; the correct spelling would be @staticmethod, not @staticclass. Since the latter would produce a name error I'm sure you knew that already. :-)

I wish this help you You created a circular import; when importing MainWindow from TopWindow, the TopWindow class is not yet defined, so the TopWindow module as seen by MainWindow doesn't have that attribute.
Postpone importing in the TopWindow class:
code :
class TopWindow:
    def import(self):
        ....
        import MainWindow
        MainWindow.MainWindow().addtolistbox()
class TopWindow:
    def import(self):
        ....
        import MainWindow
        MainWindow.run.addtolistbox()

I wish did fix the issue. Because the whole class sched cannot be serialized in Database, class MUST be defined as static. So I changed the class to static class.
code :
from datetime import datetime
from time import sleep
from apscheduler.schedulers.background import BackgroundScheduler
from apscheduler.jobstores.sqlalchemy import SQLAlchemyJobStore


class sched:
    jobstores = {
        'default': SQLAlchemyJobStore(url='sqlite:///test.db')
    }
    scheduler = BackgroundScheduler(jobstores=jobstores)
    @classmethod
    def add_func(cls, some_func, args={}, kwargs={}):
        cls.scheduler.add_job(
            some_func, 'interval', args=args, kwargs=kwargs, seconds=5, replace_existing=True)

    @classmethod
    def start(cls):
        cls.scheduler.start()

    @classmethod
    def tick(cls, i, j, **kwargs):
        print("hello{} {}".format(i, j))
        for k in kwargs:
            print(k, ":", kwargs[k])

if __name__ == '__main__':
    schedule = sched()
    schedule.start()
    schedule.add_func(schedule.tick, args=[1, 2], kwargs=dict(a=1, b=2))
    while True:
        sleep(.1)

wish help you to fix your issue Python's import is nothing like C or PHP style includes. Python has no global namespace, each module (or script) is it's own namespace, so each module must explicitely import the libs it depends on.
In your case, the solution is simple: move (or copy) the needed imports in your CCState.py module.
